  What is Inheritance Whennew classes inherit some of the properties and behavior of the existing classes, this technique is known as Inheritance. The existing class or the "parent" of a new class is called a base class and the new class that inherits properties of the base class is called derived class. Inheritance is a technique of code reuse.
