Interface inheritace

[sameera liyanage]

is that true interface doesn't support inheritance?
then what happen when we extends one interface to another

[Hector Tenedero]

This should clear things out

[sameera liyanage]

No,i didn't get the answer
is interface support inheritance
tell me "yes or no"

[Jesper de Jong]

An interface can extend another interface, and so an interface can inherit method signatures from another interface. So yes, interfaces do support inheritance.

[Larry Frissell]

Jesper, I am not sure that I agree, I guess the answer would depend on the meaning of "inheritance". In the Sun tutorial in the discussion of inheritance it states "Object-oriented programming allows classes to inherit commonly used state and behavior from other classes". In the discussions of interfaces they use the term "extends" when they rewrite the interface, but not inherit.

My point is that you can add methods to an interface, but you can not inherit the state or behavior.
