Java supports multiple inheritence indirectly through the
use of interface. In case we are able to extend more than
one class then there would be a confusion of which method to
process in case both classes have same method name(Same
method signature also).

In case of using interfaces to support multiple inheritance
we escape this problem as we define the methods that are
needed only.
