A subclass is a class derived from the superclass. It inherits the properties of the superclass and also contains attributes of its own. An example is: Car, Truck and Motorcycle are all subclasses of the superclass Vehicle. They all inherit common attributes from vehicle such as speed, colour etc. while they have different attributes also i.e Numbe...
A superclass is the class from which many subclasses can be created. The subclasses inherit the characteristics of a superclass. The superclass is also known as the parent class or base class. In the above example, Vehicle is the Superclass and its subclasses are Car, Truck and Motorcycle.
Inheritance is basically the process of basing a class on another class i.e to build a class on a existing class. The new class contains all the features and functionalities of the old class in addition to its own. The class which is newly created is known as the subclass or child class and the original class is the parent class or the superclass.

A superclass is a class from which other classes inherit, while a subclass is a class that inherits from a superclass. In this article, we will explore the attributes of subclasses and superclasses, highlighting their similarities and differences. Definition and Purpose.
- is-a relationship. In Java, inheritance is an is-a relationship. That is, we use inheritance only if there exists an is-a relationship between two classes.
- Method Overriding in Java Inheritance. In Example 1, we see the object of the subclass can access the method of the superclass. However, if the same method is present in both the superclass and subclass, what will happen?
- super Keyword in Java Inheritance. Previously we saw that the same method in the subclass overrides the method in superclass. In such a situation, the super keyword is used to call the method of the parent class from the method of the child class.
- protected Members in Inheritance. In Java, if a class includes protected fields and methods, then these fields and methods are accessible from the subclass of the class.
Definitions: A class that is derived from another class is called a subclass (also a derived class, extended class, or child class). The class from which the subclass is derived is called a superclass (also a base class or a parent class).
