Below example shows code for constructor. composition in Java. The main idea behind the inheritance in Java is that you are allowed to create new classes upon the existing classes. For example when class A and B extends class C & another class D extends class A then this is a hybrid inheritance, because it is a combination of single and hierarchical inheritance. By default, a Java program calls the subclass method if it’s invoked through a reference to the subclass. Java does not support multiple inheritance (not to be confused with multi-level inheritance) Multiple inheritance is the form of inheritance where a class can extend more than one super class. It is similar to the example of Externalizable interface but you just need to call methods of super class so as to read and write the data. In Java programming, inheritance provides user to create a class that uses the properties or qualities of previous defined class, but defined class still uses its own properties.

(C++ Supports Multiple Inheritance). With the help of inheritance it is possible to form new classes using already defined and more generalized ones. One of the absolute key aspects of Object Oriented Programming (OOP), which is the concept that C# is built upon, is inheritance, the ability to create classes which inherits certain aspects from parent classes. Python not only supports inheritance but multiple inheritance as well. In simpler terms, multiple inheritance means a class extending more than one class.
