Multiple Inheritance in Java

In Java a class can be derived from only one base class. That is, the following declaration is not allowed:

class C extends A, B // Wrong;
{
}

Nevertheless, it is possible for a class to extend a base class and to implement one or more interfaces:

class C extends A 

implements D, E
{
}

The derived class c inherits the members of A and it implements all the methods defined in the interfaces D and E.
