At a time one thread is allowed to operate on a map object. Singleton classes can be used as a method parameter. The two aspects of the modern operating system are multiprogramming and multitasking. Boot Block in Operating System; Microkernel in Operating Systems; Difference between BFS and DFS; Class method vs Static method in Python; Difference between comparing String using == and .equals() method in Java; Differences between TCP It can access the static members of the class only. The condition here is also a boolean expression, which is true for all non-zero value. This means that you can call a static Duplicates keys are not allowed, but values can be duplicated. Popular Articles serialVersionUID in Java Serialization Java Serialization At a time multiple threads are allowed to operate on map objects safely. In general, these are used to initialize the static members. Memory is allocated once the object is created. It is not possible to call non-static method within static method. What are the differences between a HashMap and a Hashtable in Java? Every method in java defaults to a non-static method without static keyword preceding it.Non-static methods can access any static method and static variable, without creating an instance How do I generate random integers within a specific range in Java? We do not currently allow content pasted from ChatGPT on Stack Overflow; read our policy here. Conversely, the alternate name for the do-while loop is the exit-controlled and post-checking loop, the reason behind this is that the checking of the loop condition is followed by the execution of the body of the loop. Change the static method to a non-static. Static variables in a Function: When a variable is declared as static, space for it gets allocated for the lifetime of the program.Even if the function is called multiple times, space for the static variable is allocated only once and the value of variable in the previous call gets carried through the next function call. Received a 'behavior reminder' from manager. It sounds like the method really should be static (i.e. Java supports Static Instance Variables, Static Methods, Static Block, and Static Classes. 3. In this article, I am going to discuss the Static vs Non-Static Members in C# with Examples. In 'do-while' loop the controlling condition appears at the end of the loop. Static block is also known as a static initialization block whereas instance block is also known as instance initialization block or non-static block. They can be simply invoked using the name of the class that holds the static method. It is not possible to call non-static method within static method. In FSX's Learning Center, PP, Lesson 4 (Taught by Rod Machado), how does Rod calculate the figures, "24" and "48" seconds in the Downwind Leg section? We apologize for any inconvenience and are here to help you find similar resources. Difference between static class and singleton pattern? Difference between static and non-static variable> 2) Static method static methods are also known as class methods. The main difference between a static and final keyword is that static is keyword is used to define the class member that can be used independently of any object of that class.Final keyword is used to declare, a constant variable, a method which can not be overridden and a class that can not be inherited.. Another definition could be that AI is basically the study of training your machine(computers) to mimic a human brain and its thinking capabilities. Static classes can contain static members only. Scheduler works independently. Portableh. Deep Learning: Deep Learning is basically a sub-part of the broader family of Machine Learning which makes use of Neural Networks(similar to the neurons working in our brain) to mimic human brain-like behavior. Syntax static { //some statements } Example ; 1. The only way to call a non-static method from a static method is to have an instance of the class containing the non-static method. A static java inner class cannot have instances. Time taken by scheduler is usually negligible.Hence we neglect it. A static class cannot be instantiated and can only contain static members. Static Variables. The aim is to increase accuracy not caring much about the success ratio. Difference between static and non-static java inner class. Other alternatives are private, protected, package and package-private.See here for more details.. static means that the method is associated with the class, not a specific instance (object) of that class. Does integrating PDOS give total charge of a system? This is just fantasy, unless the method you want to call is defined in. On the contrary, there is no use of the semi-colon in the while loop syntax. There are no different types in dispatcher.It is just a code segment. In the static method, the method can only access only static data members and static methods of another class or same class but cannot access non-static methods and variables. Defining the related or helper classes is possible inside the class by making it static. Working of dispatcher is dependent on scheduler.Means dispatcher have to wait until scheduler selects a process. The entire process makes observations on data to identify the possible patterns being formed and make better future decisions as per the examples provided to them. Distributedd. It supports Dependency Injection (DI) implementation as Singleton follows OOPS concepts. Where K is key and V is the value of a hashtable. The static class provides a nice namespace for the nested class. How to Check the Accessibility of the Static and Non-Static Variables by a Static Method? This continues in the same way for P3, and then P4. Calling Non-Static Method In Static Method In Java [duplicate], Cannot make a static reference to the non-static method. Here we will be discussing out one by one individually then rolling onto the difference after having an adequate understanding of all three of them. DL is a ML algorithm that uses deep(more than one layer) neural networks to analyze data and provide output accordingly. Static is a language feature and not an Architectural pattern. So non-static method will not get object for its instantiation inside static method, thus making it incapable for being instantiated. Static It can be applied to nested static class, variables, methods and block. Scheduler performs three task. With his example he creates an instance of the class and only uses it for one method, only to have it dispose of it later. Method overriding is one of the way by which java achieve Run Time Polymorphism.The version of a method that is executed will be determined by the object that is used to invoke it.If an object of a parent class is used to invoke the method, then the version in the parent class will be executed, but if an object of the subclass is used to invoke the method, A class needs to be instantiated first to invoke a non static method, but static methods do not have this requirement. From Java 8, it can have default and static methods also. Difference Between Recursion and Iteration, Difference Between For and Foreach in PHP, Difference Between while and do-while Loop, Difference Between Guided and Unguided Media, Difference Between Preemptive and Non-Preemptive Scheduling in OS, Difference Between dispose() and finalize() in C#, Difference Between View and Materialized View, Difference Between Server-side Scripting and Client-side Scripting, Difference Between Assembler and Interpreter, Difference Between Actual and Formal Parameters, Difference Between Cache Memory and Register. This function involves the following: The Difference between the Scheduler and Dispatcher Consider a situation, where various processes are residing in the ready queue waiting to be executed. but (StaticMethod=new Static method()) we are calling method one (sm.methodOne()). (The Java Language Specification mentions this in section 9.4: "Note that a method declared in an interface must not be declared static, or a compile-time error occurs, because static methods cannot be abstract."). This static method cannot hide the instance method from xInterface. Similarities: Both SJF and SRJF are practically not feasible as it is not possible to predict the burst time of the processes. non-static method cannot be referenced from a static context. Comparison Chart The class in which the nested class is defined is known as the Outer Class. JAVA Programming Foundation- Self Paced Course, Data Structures & Algorithms- Self Paced Course, Difference Between Hashtable and Synchronized Map in Java, Getting Synchronized Map from Java HashMap, Getting Synchronized Map from Java TreeMap, Difference Between Atomic, Volatile and Synchronized in Java, Difference Between Synchronized ArrayList and CopyOnWriteArrayList in Java Collection, Java Program to Copy the Map Content to Another Hashtable. Browse other questions tagged, Where developers & technologists share private knowledge with coworkers, Reach developers & technologists worldwide. The logic behind it is we do not create an object to instantiate static method, but we must create an object to instantiate non-static method. Since you used the term "static class", I understand that the whole class is probably dedicated to utility-like methods that could be static. While one thread iterating map objects the other thread is allowed to modify the map and wont get ConcurrentModificationException. Job scheduling (Long-term scheduler), Jumping to the proper location in the user program to restart that program. Implement 2 methods in your class: an instance method (as defined in. The iterations do not occur if, the condition at the first iteration, appears false. Multiprogramming Multiprogramming is known as keeping multiple programs in the main memory at the same time ready for execution. Because here we are creating reference which nothing but "sm" by using that reference of that class which is nothing As a rule I rarely create public fields and similarly I rarely create non-public properties. In cooperative multitasking, the operating system never initiates context switching from the running process to another process.A context switch occurs only when the processes voluntarily yield control periodically or when idle or logically blocked to allow multiple applications to execute simultaneously. Lastly, discussing out Synchronized Map before landing upon conclusive differences between all three of them. Compare static and non-static methods through their relation to variables and classes in Java. Is like when you try to invoke the non-static method startsWith of class String without an instance: What you need is to have an instance and then invoke the non-static method: So you need to create and instance to invoke it. Let us start with ConcurrentHashMap first. It cannot dispose of the static class as there is no instance created. The efficiency Of AI is basically the efficiency provided by ML and DL respectively. Unlike top-level classes, Inner classes can be Static. Is it appropriate to ignore emails from a student asking obvious questions? A non-static variable is declared as a regular variable. If you have a class A, a 'normal' (usually called instance) method b, and a static method c, and you make an instance a of your class A, the calls to A.c() and a.b() are valid. Different objects trying to invoke an object instantiated as singleton. Multitasking Multitasking is nothing but multiprogramming with a Round-robin scheduling algorithm. acknowledge that you have read and understood our, Data Structure & Algorithm Classes (Live), Full Stack Development with React & Node JS (Live), Fundamentals of Java Collection Framework, Full Stack Development with React & Node JS(Live), GATE CS Original Papers and Official Keys, ISRO CS Original Papers and Official Keys, ISRO CS Syllabus for Scientist/Engineer Exam, Process Table and Process Control Block (PCB), Threads and its types in Operating System, First Come, First Serve CPU Scheduling | (Non-preemptive), Program for FCFS CPU Scheduling | Set 2 (Processes with different arrival times), Shortest Remaining Time First (Preemptive SJF) Scheduling Algorithm, Longest Job First (LJF) CPU Scheduling Algorithm, Longest Remaining Time First (LRTF) or Preemptive Longest Job First CPU Scheduling Algorithm, Longest Remaining Time First (LRTF) CPU Scheduling Program, Round Robin Scheduling with different arrival times, Program for Round Robin Scheduling for the same Arrival time, Multilevel Feedback Queue Scheduling (MLFQ) CPU Scheduling, Program for Preemptive Priority CPU Scheduling, Highest Response Ratio Next (HRRN) CPU Scheduling, Difference between FCFS and Priority CPU scheduling, Comparison of Different CPU Scheduling Algorithms in OS, Difference between Preemptive and Non-preemptive CPU scheduling algorithms, Difference between Turn Around Time (TAT) and Waiting Time (WT) in CPU Scheduling, Difference between LJF and LRJF CPU scheduling algorithms, Difference between SJF and SRJF CPU scheduling algorithms, Difference between Arrival Time and Burst Time in CPU Scheduling, Difference between EDF and LST CPU scheduling algorithms, Difference between First Come First Served (FCFS) and Round Robin (RR) Scheduling Algorithm, Difference between Multilevel Queue (MLQ) and Multi Level Feedback Queue (MLFQ) CPU scheduling algorithms, Difference between Long-Term and Short-Term Scheduler, Difference between Preemptive and Cooperative Multitasking, Multiple-Processor Scheduling in Operating System, Earliest Deadline First (EDF) CPU scheduling algorithm, Advantages and Disadvantages of various CPU scheduling algorithms, Producer Consumer Problem using Semaphores | Set 1, Dining Philosopher Problem Using Semaphores, Sleeping Barber problem in Process Synchronization, Readers-Writers Problem | Set 1 (Introduction and Readers Preference Solution), Introduction of Deadlock in Operating System, Deadlock Detection Algorithm in Operating System, Resource Allocation Graph (RAG) in Operating System, Memory Hierarchy Design and its Characteristics, Buddy System Memory allocation technique, Fixed (or static) Partitioning in Operating System, Variable (or dynamic) Partitioning in Operating System, Non-Contiguous Allocation in Operating System, Logical and Physical Address in Operating System, Page Replacement Algorithms in Operating Systems, Structures of Directory in Operating System, Free space management in Operating System, Program for SSTF disk scheduling algorithm, SCAN (Elevator) Disk Scheduling Algorithms. How to prevent Singleton Pattern from Reflection, Serialization and Cloning? Java. By using our site, you Static class cannot be used as a method parameter. Dispatcher allocates the CPU to the process selected by the short-time scheduler. Difference Between Static and Non Static Nested Class in Java, Difference between static and non-static method in Java, Difference between static and non-static variables in Java, Class Loading and Static Blocks Execution Using Static Modifier in Java, Difference between Static-1 and Static-0 hazard. 2) Abstract class doesn't support multiple inheritance. Static variables reduce the memory footprint of the program. Thus instance of a class is an object. I use an interface and create an anonymous instance of it like so: Not as elegant as creating an instance of that class and calling its own method, but accomplishes the same thing, essentially. Object contains instance members (non-static members). In general, these are used to initialize the static members. Examples of ML applications include: Virtual Personal Assistants: Siri, Alexa, Google, etc., Email Spam and Malware Filtering. static methods and static blocks Static methods belong to the class and they will be loaded into the memory along with the class, you can invoke them without creating an object. Java Keywords Non-static method: Any method whose definition doesnt contain the static keyword is a non-static method. This is because after the processes are added in the ready queue, no preemption is carried out. This type of situation is very common in android app development eg:- An Activity has at-least one instance. Static classes are able to access only the static members of their enclosing class. Call the non-static method from an instance within the static method. Their main task is to select the jobs to be submitted into the system and to decide which process to run. it doesn't access any data members and it doesn't need an instance to be invoked on). This way you'll be invoking the method on an instance, but at least you won't be creating new instances each time you need to call the method. Boot Block in Operating System; Microkernel in Operating Systems; Difference between BFS and DFS; Class method vs Static method in Python; Difference between comparing String using == and .equals() method in Java; Differences between TCP At a time only one thread is allowed to perform any operation on a map object. How Artificial Intelligence (AI) and Machine Learning(ML) Transforming Endpoint Security? Static Class . AI stands for Artificial Intelligence, and is basically the study/process which enables machines to mimic human behaviour through particular algorithm. Debian/Ubuntu - Is there a man page listing all the version codenames/numbers? The syntax of a do-while loop includes a semi-colon to terminate the loop. The easiest way to use a non-static method/field within a a static method or vice versa is (To work this there must be at least one instance of this class). The above constructor creates an empty hashtable object with an initial default capacity of 11 and a default fill ratio of 0.75. It can implement any other interface or base class is required. The above constructor creates an empty ConcurrentHashMap with. We will get thread safety without locking the total map object just with a bucket level lock. So as long as the method is present in xInterface, and your class implements xInterface, you won't be able to make the method static. You need an instance of the class containing the non static method. That is why a static class is also known as a static inner class or static nested class. Find centralized, trusted content and collaborate around the technologies you use most. e.g. In Java, Static classes are a convenient way of grouping classes together. Static nested classes are nested classes that are declared static. There would only be one copy of each class variable per class, regardless of how many objects are created from it. If we want any logic that needs to be executed at the time of class loading that logic needs to placed inside the static block so that it will be executed at the time of class loading.

Static. Java doesnt allow you to create top-level static classes; only nested (inner) classes. A-143, 9th Floor, Sovereign Corporate Tower, We use cookies to ensure you have the best browsing experience on our website. Machine Learning: Machine Learning is basically the study/process which provides the system(computer) to learn automatically on its own through experiences it had and improve accordingly without being explicitly programmed. Difference between HashMap and ConcurrentHashMap, Difference Between ConcurrentHashMap and SynchronizedHashMap, Getting Synchronized Set from Java HashSet. By definition, a non-static method is one that is called ON an instance of some class, whereas a static method belongs to the class itself. For example, you could just "new up" an instance of your class in the static method, then call the non-static method. Classname.class.method(), Site design / logo 2022 Stack Exchange Inc; user contributions licensed under CC BY-SA. Actually as per my understanding, calling non static method with instance is beyond the scope of this question. These variable are created when the block in entered or the function is called and destroyed after exiting from the block or when the call returns from the function. Default concurrency level 16 where K is key and V is the value of ConcurrentHashMap. Read operation can be performed without lock but write operation can be performed with bucket level lock. Thus, when an initialization cycle happens, the temporary object containing only constants and non-static methods which are dynamically initialized through dependency injection can be safely loaded and discarded as needed. static block 1 static block 2 Main Method. AI is a combination of two words: Artificial meaning something made by humans or non-natural things and Intelligence meaning the ability to understand or think accordingly. Unique paths covering every non-obstacle block exactly once in a grid; Depth First Search or DFS for a Graph; Breadth First Search or BFS for a Graph; Level Order Binary Tree Traversal; Tree Traversals (Inorder, Preorder and Postorder) Class method vs Static method in Python; Difference between comparing String using == and .equals() method in Java Let us finally conclude out the differences between them to get a tight grip to understand the minute difference between them. An XSL stylesheet processor accepts a document or data in XML and an XSL stylesheet and produces the presentation of that XML source content that was intended by the designer of that stylesheet. A-143, 9th Floor, Sovereign Corporate Tower, We use cookies to ensure you have the best browsing experience on our website. If you have a clear idea about the logic(math) involved in behind and you can visualize the complex functionalities like K-Mean, Support Vector Machines, etc., then it defines the ML aspect. By using our site, you Static Method in Java. Now dwelling on the second concept that is HashTable. In Java, Static classes are a convenient way of grouping classes together. Connect and share knowledge within a single location that is structured and easy to search. Dispatcher is also responsible for:Context Switching, Switch to user mode, Jumping to proper location when process again restarted. But you might get even better suggestions if you post your class(es) -- or a slimmed-down version of them. Please read our previous article before proceeding to this article where we discussed the Data Types in C# with Examples. Static methods can access all static variables, but cannot access non-static (instance variables) Important points about overriding static methods > Multithreading is an extension of multitasking. Multi Out of scope for Garbage Collector as it uses stack memory. Singleton design pattern is used when we need to ensure that only one object of a particular class is Instantiated. calling a move() method on a Player object most likely changes its position. Memory is allocated immediately after any of the class members is accessed. Measure the time spent in context switch? ML is an application or subset of AI. They also have side effects e.g. Singleton implementation can either have static members or instance members. In this scheduling algorithm, the process with the smallest amount of time remaining until completion is selected to execute. The only work of scheduler is selection of processes. @EJP For security purposes, and this is what I do with my project, in the case of dependency injection, it is useful to only have initialization code be instantiated for initialization, and not at the arbitrary discretion of code using my API. HashTable is the best choice if our frequent operation is search operation. Examples of AI applications include: Googles AI-Powered Predictions, Ridesharing Apps Like Uber and Lyft, Commercial Flights Use an AI Autopilot, etc. The while loop is also known as the entry-controlled and pre-checking loop because in this loop, the body of the loop is executed prior to checking the condition. Read more about modifiers in our Java Modifiers Tutorial. Static and non-static methods are elementary to comprehend. Individual subscriptions and access to Questia are no longer available. Is Java "pass-by-reference" or "pass-by-value"? I'm getting an error when I try to call a non-static method in a static class. Is energy "equal" to the curvature of spacetime? By far we have discussed enough the concepts along with internal working through implementation in the programs. AI focuses on 3 major aspects(skills): learning, reasoning and self-correction to obtain maximum efficiency possible. The major aim of ML is to allow the systems to learn by themselves through the experience without any kind of human intervention or assistance. Cannot make a static reference to the non-static method methodName() from the type playback. You could create an instance of the class you want to call the method on, e.g. How do I call a method into the public static class to be used? Guidelines for Singleton Pattern are as follows: Static nested classes are nested classes that are declared static. We need not to create instance of class for accessing static methods. As the name suggests, the creational design type deals with object creation mechanisms. else its not allowed. The underlying data structure for HashTable is HashTable. 5. It can be applied to nested static class, variables, methods and block. Simplec. In general, these are used to initialize the static members. This variable can be re-initialized. Just another way to do it. Now lets wrap it up by illustrating all differences in a tabular format which is as follows: JAVA Programming Foundation- Self Paced Course, Data Structures & Algorithms- Self Paced Course. Make the class a singleton: make the constructor private, and have a static data member in the class to hold the only existing instance. Both SJF and SRJF may lead to process starvation as long processes may be held off indefinitely if short processes are continually added. CGAC2022 Day 10: Help Santa sort presents! Example There are 4 processes in the ready queue, P1, P2, P3, P4; Their arrival times are t0, t1, t2, t3 respectively. Interface has only static and final variables. Root: This account is the main user account of a Linux system, it has the highest privilege to work administrative A non-static variable is accessible to its instance (where it is defined). Firstly create a class Instance and call the non-static method using that instance. In this post, we will understand the difference between static and final keywords in Java. However, each time a new object is created new memory space is allotted which can lead to wastage of memory. An abstract class may contain non-final variables. The static blocks don't have any name in its prototype. 2. A-143, 9th Floor, Sovereign Corporate Tower, We use cookies to ensure you have the best browsing experience on our website. It implements Serializable and cloneable interfaces but not RandomAccess. If you are clear about the math involved in it but dont have idea about the features, so you break the complex functionalities into linear/lower dimension features by adding more layers, then it defines the DL aspect. Class variables also known as static variables are declared with the static keyword in a class, but outside a method, constructor or a block. ML stands for Machine Learning, and is the study that uses statistical methods enabling machines to improve with experience. An object is something that can adhere to encapsulation, polymorphism, abstraction principles of object oriented programming and the real thing a program interacts with to consume the instance members defined in class. DL stands for Deep Learning, and is the study that makes use of Neural Networks(similar to neurons present in human brain) to imitate functionality just like a human brain. Not sure if it was just me or something she sent to the whole team, Connecting three parallel LED strips to the same power supply, Concentration bounds for martingales with adaptive Gaussian steps. How do I read / convert an InputStream into a String in Java? Multiprocessing A computer using more than one CPU at a time. Singleton Pattern belongs to Creational type pattern. When the scheduler completes its job of selecting a process, it is the dispatcher which takes that process to the desired state/queue. Provide global instance to that access by declaring all constructors of the class to be private, providing a static method that returns a reference to the instance, and the instance is stored as a private static variable. So, this procedure of selecting a process among various processes is done by the scheduler. How Machine Learning and Artificial Intelligence Will Impact Global Industries in 2020? They execute before the instance block whereas instance block executes after the static blocks. Constructor is a special method which in theory is the "only" non-static method called by any static method. Both SJF and SRJF are considered same once all the processes are available in the ready queue. Why can't I define a static method in a Java interface? In contrast, if the condition in do-while loop is false, then also the body of the loop is executed at least once then the condition is tested. It can access the private member of the enclosing class through the object reference. A static method is a method that belongs to a class, but it does not belong to an instance of that class and this method can be called without the instance or object of that class. I can't make the method static as this gives me an error too. Null is not allowed for both keys and values. 1.1 Processing a Stylesheet. In the United States, must state courts follow rulings by federal courts of appeals? This is because the memory is allocated only once for a static variable during the time of class loading, while for a non-static variable, memory is allocated every time an instance of the class is created. Non-static method cannot be referenced from a static context (Java). Shortest Job First (SJF) :The Shortest Job First (SJF) is a scheduling policy that selects the waiting process with the smallest execution time to execute next. Let's see an example to understand how a static and non-static method It attains the highest rank in terms of accuracy when it is trained with large amount of data. ConcurrentHashMap allows concurrent read and thread-safe update operations. The purpose of static methods is more like the purpose of "pure" functions such as in functional programming languages. The static blocks are executed before running the main () method. This method is present in java.util.Collections. If the condition in a while loop is false, not a single statement inside the loop is executed. The solution for you is It can be called only by other static methods. Artificial Intelligence: Artificial Intelligence is basically the mechanism to incorporate human intelligence into machines through a set of rules(algorithm). 1. A non-static java inner class can have instances that belong to the outer class. Java is a Object Oriented Programming(OOP) language, which means we need objects to access methods and variables inside of a class.However this is not always true. rev2022.12.11.43106. More powerful than ML as it can easily work for larger sets of data. By using our site, you See fabien's answer for an oneliner sample although I would strongly recommend against it. There are two aspects of this presentation process: first, constructing a result tree from the XML source tree and second, interpreting the result tree Japanese girlfriend visiting me in Canada - questions at border control? Basically, to simplify this, creational pattern explains to us the creation of objects in a manner suitable to a given situation. ML focuses on the development of programs so that it can access data to use it for themselves. Conclusion. Dispatcher A dispatcher is a special program which comes into play after the scheduler. It is not required to initialize the static variable when it is declared. thanks, approach is clearer, help me lot ! the above code not executed because static method must have that class reference. Preemptive and Non-Preemptive Scheduling; Difference between BFS and DFS; Class method vs Static method in Python; Difference between comparing String using == and .equals() method in Java; Differences between TCP and UDP; Stack vs Heap Memory Allocation; Write an Article. Static class can only be an inner class or a nested class. We will get thread safety by locking the whole map object. 2. Difference between dispatcher and scheduler, Monolithic Kernel and key differences from Microkernel, Privileged and Non-Privileged Instructions in Operating System, Difference between comparing String using == and .equals() method in Java, Differences between Black Box Testing vs White Box Testing, Differences between Procedural and Object Oriented Programming, Difference between Structure and Union in C, Difference between Primary Key and Foreign Key, Difference between Clustered and Non-clustered index, Dispatcher is a module that gives control of CPU to the process selected by short term scheduler, Scheduler is something which selects a process among various processes. It ensures there is only one object available across the application in a controlled state. Help us identify new roles for community members, Proposing a Community-Specific Closure Reason for non-English content, calling another method from the main method in java, why you can call a non-static method in the main method by creating an object? 4) Abstract class can provide the implementation of interface. Both SJF and SRJF are practically not feasible as it is not possible to predict the burst time of the processes. Java doesnt allow you to create top-level static classes; only nested (inner) classes.
