How Inheritance Works In Java?

In Java, inheritance is a mechanism by which a class can inherit properties and behaviors (methods and fields) from another class. The class that is being inherited from is called the superclass or base class, and the class that inherits from it is called the subclass or derived class. Internally, when a subclass inherits from a superclass, it gains access to all the public and protected members of the superclass. This is achieved through a process called subclassing, where the subclass maintains a reference to its superclass.  When an object of a subclass is created, memory is allocated for both the subclass and the superclass. The superclass portion of the object is initialized first, followed by the subclass portion. This ensures that all the fields and methods from the superclass are available to the subclass object. Additionally, Java uses the concept of method overriding to allow a subclass to provide its own implementation of a method that is already defined in its superclas...

Introduction To Inheritance in OOPS

Introduction Inheritance is a fundamental concept in object-oriented programming (OOP) where classes can inherit properties and behaviors from other classes. It enables code reuse and establishes an "is-a" relationship between classes, allowing you to create more specialized classes based on existing ones. Inheritance promotes code reusability by allowing you to define a base class, also known as a superclass or parent class, which contains common attributes and methods. The derived classes, also known as subclasses or child classes, can inherit these characteristics and extend or modify them as needed. This avoids duplicating code and makes it easier to maintain and update your program. The "is-a" relationship is established through inheritance. When a class inherits from another class, it means that the derived class "is a" specialized type of the base class. This relationship allows you to use objects of the derived class wherever objects of the base cl...
