Could any say what's the difference between nested interfaces and extending interface in java??

Nested interface:
Specifications of interface within another interface.

Ex:
interface A{
..
public interface B{
..
}

}

Extending interface :

An interface can extends another interface so sub interface have all abstract methods of both interfaces...

Ex:
interface A {
..
}
interface B extends A
{
...
}
