Polymorphism in Java 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 […]

Abstraction in Java 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.

OOPs Concepts in Java 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,

Constructor in Java 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

Classes and Objects in Java 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

String in Java 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

Array in Java (With Examples) 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

Jump statement in java 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

Loops in Java Loops are programming constructs that allow a block of code to be executed repeatedly until a certain condition is met. They help automate repetitive tasks and facilitate efficient processing of data.The main types of loops in Java are: For Loop While Loop Do-While Loop In the below PDF we discuss about Loops in

Conditional Statements in Java Conditional Statements, also known as decision-making statements, are used to execute certain blocks of code based on specified conditions. These conditions are typically expressed as boolean expressions, which evaluate to either true or false. In Java, there are three main types of conditional statements: if statements, if-else statements, and Nested if-else
