Java is a programming language that follows the Object-Oriented Programming paradigm. One of the pillars of OOPs is Inheritance, where you can find a relationship between two classes as Parent and Child. This relationship allows these classes to reuse each other's attributes and methods. Java classes can relate to each other in many ways such as, Is-A relationship and Has-A relationship. In this article, we are going to learn the concept of Has-A relationship in Java through examples. HAS-A Relationship in Java Has-A relationship is a type of association where two classes are linked to each other through objects. Here, ... Read More

Multiple inheritance is a type of inheritance where a single subclass inherits multiple superclasses. As the name suggests, inheritance is the ability of a class to inherit members of another class. The class whose properties are inherited is called a superclass, whereas the class that inherits a superclass is called a subclass. We use the extends keyword to inherit the members of a class. Unlike other object-oriented programming languages, Java does not support multiple inheritance. As an alternative, we can implement multiple inheritances from a single class. Why Java Does Not Support Multiple Inheritance When a single class inherits the ... Read More

Multilevel inheritance - A class inherits properties from a class which again has inherits properties. Example class Shape { public void display() { System.out.println("Inside display"); } } class Rectangle extends Shape { public void area() { System.out.println("Inside area"); } } class Cube extends Rectangle { public void volume() { System.out.println("Inside volume"); } } public class Tester { public static void main(String[] arguments) { Cube cube = new Cube(); cube.display(); cube.area(); cube.volume(); } } Output Inside display Inside area Inside volume Read Also: Java Inheritance

Single Level inheritance - A class inherits properties from a single class. For example, Class B inherits Class A.Example Live Democlass Shape {    public void display() {       System.out.println("Inside display");    } } class Rectangle extends Shape {    public void area() {       System.out.println("Inside area");    } } public class Tester {    public static void main(String[] arguments) {       Rectangle rect = new Rectangle();       rect.display();       rect.area();    } }OutputInside display Inside areaHere Rectangle class inherits Shape class and can execute two methods, display() and area() as shown.
