What is Inheritance? Inheritance is a mechanism that allows one class to inherit properties or behaviors from another class. Multiple classes can inherit from the same parent class, forming a tree-like hierarchy structure. Inheriting classes can add features beyond those inherited from the parent class to allow for unique behavior.In Java , when you think of a class having that has a member of a different type, then there an association can be formed.

Inheritance applies to classes, whereas polymorphism applies to methods. The importance of polymorphism and inheritance Below are a few reasons why polymorphism and inheritance are essential OOP concepts: Rule 1: Override the conflicting method with an abstract method. For example: interface four extends one, two {. // Implementing another method. void print (); } Rule 2: Override the conflicting method with a default method and provide a new implementation.

Inheritance is one of the useful feature of OOPs. It allows a class to use the properties and methods of another class. The purpose of inheritance in java, is to provide the reusability of code so that a class has to write only the unique features and rest of the common properties and functionalities can be inherited from the another class.Java Inheritance is the concept of Object-Oriented Programming (OOPs). Where an Object ( class or Interface) acquires the property ( Methods, Variables, etc) of another object. It's also called Java extends the class. So the idea behind this concept is the usability of code, which means when you create a new class (child class).Inheritance and Composition both are design techniques. The Composition is a way to design or implement the "has-a" relationship whereas, the Inheritance implements the "is-a" relationship. The "has-a" relationship is used to ensure the code reusability in our program. In Composition, we use an instance variable that refers to another object.Multiple Inheritance in Java Multiple inheritance in java is the capability of creating a single class with multiple superclasses. Unlike some other popular object oriented programming languages like C++, java doesn't provide support for multiple inheritance in classes.1. Definitions Inheritance - allows a new class to extend an existing class; the new inherits the member methods and variables In definition above, existing class is the superclass ; the new class is the subclass .In Java, when an ‘I-A’ relationship occurs between the two classes we use inheritance. The parent class is defined as the superclass and the inherited class is known as the superclass. The ‘extend’ keyword is used by the subclass for inheriting the features of the superclass. Inheritance is essential since it focuses on reusability of code.Inheritance in Java:- Inheritance in Java is a mechanism where an element acquires all houses and behaviors of a discerning element.
