Encapsulation can be defined as the bundling of data and methods that operate on the data into a single unit, known as a class. It allows for the hiding of the internal state of an object and restricting access to it from outside the class. In simpler terms, encapsulation enables us to control the access […]

Inheritance is a mechanism in Java that allows a new class to inherit properties and behaviors (methods) from an existing class, known as the superclass or parent class. The class that inherits these properties is called the subclass or child class. This relationship between classes forms an “is-a” hierarchy, where a subclass is essentially a

Polymorphism, derived from the Greek words “poly” meaning many and “morph” meaning form .Polymorphism in Java refers to the ability of objects to take on multiple forms or the ability of methods to behave differently based on the object that calls them. It allows objects of different classes to be treated as objects of a

Abstraction is the process of hiding the implementation details while showcasing only the essential features of an object. In Java, abstraction is achieved through two primary mechanisms: Abstract classes and Interfaces. In the below PDF we discuss about String in Java  in detail in simple language, Hope this will help in better understanding. Implementing Abstraction in

Object-Oriented Programming is a programming paradigm that revolves around the concept of objects. Objects are instances of classes, which serve as blueprints for creating these objects. Each object encapsulates data (attributes) and behaviors (methods), allowing for a modular and organized approach to software development. OOP emphasizes principles such as encapsulation, inheritance, polymorphism, and abstraction to

In Java, a constructor is a special type of method that is invoked when an object is created. Its primary purpose is to initialize the newly created object. Constructors are called automatically when an object of a class is created, and they typically set initial values for the object’s attributes or perform other necessary setup

In Java, A Class is a blueprint or template for creating objects. It defines the properties (attributes) and behaviors (methods) that objects of that class will have.On the other hand, An object is an instance of a class, created using the new keyword followed by the class name. Each object has its own set of

In Java, A String is an object that represents a sequence of characters. Unlike some other programming languages where strings are treated as primitive data types, in Java, strings are objects of the String class. Strings in Java are immutable, meaning their values cannot be changed after they are created. This means that operations such

An Array is a linear data structure used to store a fixed-size collection of elements of the same type. It allows you to store multiple values of the same data type under a single variable name. Arrays are commonly used for grouping related data items together, such as a list of numbers, strings, or objects.

Jump Statements in Java are control flow statements that alter the normal flow of execution within a program. They allow you to transfer control to another part of the program, such as jumping out of a loop prematurely, skipping iterations, or branching to a different section of code based on certain conditions. Java provides three
