Hi, Aruna how r u doing?

In Java multiple inhritance provided through interfaces
by extending morethan one interface. We can extend more
than one class in C++. But this is not possible in java
that's why java doesn't support mutiple inhritance
directly.
public interface GroupedInterface extends Interface1,
Interface2,
Interface3

An interface can extend other interfaces, just as a class
can extend or subclass another class. However, whereas a
class can extend only one other class, an interface can
extend any number of interfaces. The interface declaration
includes a comma-separated list of all the interfaces that
it extends.
Aruna if you still not understood please
