Abstract Classes and Interfaces are two key concepts in Java that enable abstraction and define contracts for classes. They are used to achieve abstraction, one of the four pillars of….
Polymorphism (Method Overloading & Overriding)
Polymorphism is one of the core concepts of Object-Oriented Programming (OOP) in Java. It allows objects to take on multiple forms and enables a single method or class to have….
Inheritance in Java
Inheritance in Java is a mechanism that allows one class to inherit the properties (fields) and behaviors (methods) of another class. It promotes code reusability and establishes a relationship between….
Constructors in Java
