![]() Garbage collector thread is what kind of a thread?ġ3. Whereas under preemptive scheduling, the task with the highest priority is executed either until it enters dead or warning states or if another higher priority task comes along. ![]() The scheduler then picks the next task to be executed based on the priority and other factors. After that, it enters the ready queue - a pool of ‘ready’ tasks. In case of time slicing, a task executes for a specified time frame – also known as a slice. Explain the differences between time slicing and preemptive scheduling? Compile server implementation with RMI compilerġ1.Compile the interface and their implementations with the java compiler.The following steps can be taken to develop an RMI object: They break the referential transparency.They create collisions in the namespace.This is primarily because of two reasons: No, Java doesn’t support global variables. Does Java support global variables? Why/Why not? We call this method before the start() method, else we get IllegalThreadStateException. We use the class setDaemon(true) to create this thread. Neither can we instantiate this class since it doesn’t provide any public constructors. Since the class is final, we cannot override its behavior through inheritance. Our learners also read: Java free online courses! Inner classes are associated with the objects of the class and they can access all methods and variables of the outer class. It always either extends a class or implements an interface, and is defined and instantiated in a single statement.Ī non-static nested class is called an inner class. ![]() Since it doesn’t have any name, it is impossible to create its constructor. What is an anonymous inner class? How is it different from an inner class?Īny local inner class which has no name is known as an anonymous inner class. It is generally overridden to release system resources when garbage value is collected from the object.Ħ. In contrast, finalize() is a special method in the object class. Used with the try-catch block, the ‘finally’ block is used to ensure that a particular piece of code is always executed, even if the execution is thrown by the try-catch block. Explain the difference between ‘finally’ and ‘finalize’ in Java? All different non-primitive are inherited directly or indirectly from this class.ĥ. But, there is ownership in this, and the child object cannot belong to any other parent object in any manner. What do you understand by Aggregation in context of Java?Īggregation is a form of association in which each object is assigned its own lifecycle. Since Java utilizes 8 primitive datatypes - boolean, byte, char, int, float, long, short, double - which are not objects, Java cannot be considered a 100% object-oriented language.ģ. Following that logic, an object-oriented language is a language that works on objects and procedure. Simply put, objects are containers – they contain data in the form of fields and code in the form of procedures. What is object-oriented programming? Is Java an object-oriented language?Įssentially, object-oriented programming is a programming paradigm that works on the concept of objects.
