interface B extends A

[Sameera Abeysinghe]

Hi all
This is my q
We can extend only one class right ?

class A
class B extends A

As for my knowledge we can extend only one interface two right ?

interface A
interface B extends A

But is there a why to extend multiple interfaces ?
Please explain with examples !

[Ernest Friedman-Hill]

An interface can extend multiple interfaces

interface C extends B, A

and a class can implement multiple interfaces

class D implements B, A

Not sure there's anything to explain.
