Inheritance is a key feature of OOP, allowing you to create flexible and reusable code. Understanding how to implement it effectively can greatly improve the structure of your programs. TheJava Programming Courseprovides real-world examples to help you see how inheritance plays out in large-scale Java applications. 1. Code Reusability: The code wri...
The extends keyword is used for inheritance in Java. Using the extends keyword indicates you are derived from an existing class. In other words, “extends” refers to increased functionality. Syntax :
Example: In the below example of inheritance, class Bicycle is a base class, class MountainBike is a derived class that extends the Bicycle class and class Test is a driver class to run the program. In the above program, when an object of MountainBike class is created, a copy of all methods and fields of the superclass acquires memory in this objec...
Below are the different types of inheritance which are supported by Java. 1. Single Inheritance 2. Multilevel Inheritance 3. Hierarchical Inheritance 4. Multiple Inheritance 5. Hybrid Inheritance
IS-A is a way of saying: This object is a type of that object. Let us see how the extends keyword is used to achieve inheritance. Now, based on the above example, in Object-Oriented terms, the following are true:- 1. SolarSystem is the superclass of Earth class. 2. SolarSystem is the superclass of Mars class. 3. Earth and Mars are subclasses of Sol...
In sub-classes we can inherit members as is, replace them, hide them, or supplement them with new members: 1. The inherited fields can be used directly, just like any other fields. 2. We can declare new fields in the subclass that are not in the superclass. 3. The inherited methods can be used directly as they are. 4. We can write a new instancemet...
Let us check some important points from the article are mentioned below: 1. Default superclass: Except Objectclass, which has no superclass, every class has one and only one direct superclass (single inheritance). In the absence of any other explicit superclass, every class is implicitly a subclass of the Object class. 2. Superclass can only be one...

To inherit from a class, use the extends keyword.
