Java - What Is Single Inheritance?
Single inheritance is simple and easy to understand. When a class extends another one class only then we call it a single inheritance.

Super Class
The class whose features are inherited is known as superclass
(or a base class or a parent class).
Sub Class
The class that inherits the other class is known as a subclass (or
a derived class, extended class, or child class). The subclass can add its own
properties and methods in addition to the superclass properties and methods.
Reusability
Inheritance supports the concept of “reusability”, i.e. when we
want to create a new class and there is already a class that includes some of
the code that we want, we can derive our new class from the existing class.
By doing this, we are reusing the fields and methods of the existing class.
