}

As an experiment, you might try removing the implementation for 

Meth1( )

 in 

MyClass

.

This will cause a compile-time error. As stated earlier, any class that implements an interface 

must implement all methods defined by that interface, including any that are inherited from 

other interfaces.

Name Hiding with Interface Inheritance

When one interface inherits another, it is possible to declare a member in the derived 

interface that hides one defined by the base interface. This happens when a member in a 

derived interface has the same declaration as one in the base interface. In this case, the base 

interface name is hidden. This will cause a warning message unless you specify the derived 

interface member with
