Define inheritance with reference to Java.

Inheritance in Java is an important concept in any object-oriented programming language. Using inheritance, one class is allowed to inherit the properties and features of another class. The properties and features include fields and methods. Inheritance takes place with the help of the keyword "extends". There is a superclass whose features are inherited. It is also known as the base class or parent class. There is a subclass that inherits the properties of the base class. It is also known as a derived class, extended class or the child class. Inheritance also supports the concept of “reusability”.
