Classes and Objects in Java
Classes in Java Classes are considered blueprints for an object. It consists of the behavior, and attributes of an object. Classes and objects are the basis of all object-oriented programming concepts. Class doesn't occupy any memory until it is instantiated. The class contains different methods and different variables in it.
Stack vs Heap Memory: Key Differences
Introduction Stack A stack is a type of memory area in a computer that stores temporary variables created by a function. Variables are declared, stored, and initialized on the stack during runtime. It is a type of temporary memory. When the computing task is finished, the variable's memory is automatically
Learn about Java List
Introduction We will study the Java List interface and its methods in this tutorial. The List interface in Java is a sequentially accessed ordered collection that lets us store elements. The Collection interface is expanded by it.. Classes that Implement List * List is an interface, so we are unable to
Java Vs Javascript: What's The Difference?
Introduction What is Java? Java is a general-purpose programming language that was created with a single guiding principle. Java is most frequently used in web development as a server-side language and as the preferred programming language for mobile apps. It still has a respectable front-end presence as a Java applet,
Introduction to Round-Robin Scheduling
What is Round-Robin Scheduling? This algorithm takes its name from the round-robin principle, which distributes something equally among all participants. This is the oldest, most straightforward scheduling algorithm used for multitasking. During round-robin scheduling, each ready task runs cyclically for a limited period. As a result of this algorithm, processes
Dynamic Method Dispatch in Run-Time Polymorphism
What is Polymorphism? As part of Object-Oriented Programming, polymorphism is considered one of the most important features. The concept of polymorphism enables us to perform the same action differently. In other words, polymorphism allows you to specify one interface but implement multiple methods. As "poly" means many, and "morphs" means
Types of Variables in Java
Introduction The definition of a variable is to set aside memory for the values to be stored. Depending on the kind of variable, they can either be initialized at the time of definition or afterward. In Java, there are primarily three types of variables: static variables, instance variables, and local
Checked vs Unchecked Exceptions in Java
Checked Exceptions Generally, a checked exception (also called a logical exception) in Java occurs when your code goes wrong and is potentially recoverable. Suppose we get a client error when calling another API; then, we could retry from that exception and see if it runs again. The compiler catches checked
Learn to Create an Array of Objects in Java
Introduction Object-oriented programming is a fundamental feature of Java, which is why so much of the work gets done with objects. As we know, arrays can contain elements of primitive types and dynamically create objects of the same type. An array is a container for objects in Java. A class
Understanding Anonymous Inner Class in JAVA
Introduction In Java, an anonymous inner class does not have a name and only creates a single object for that class. Anonymous inner classes can be helpful when creating objects with a few extras, such as overloading methods of classes or interfaces, without actually subclassing them. Simply put, an anonymous
