Extendibility It is an important part of OOPs (Object Oriented programming system).. c) Depends on how we call the object What will be the order of execution of base class constructors in the following method of inheritance.class a: public b, public c {...}; A. b(); c(); a(); -You expect that unrelated classes would implement your interface. In this tutorial, you will be learning about inheritance and its uses and types. For example, the inheritance graph does not allow a Student object to become a Employee object while retaining the state of its Person superclass.
