Have a look at this code below
interface E {
interface G {
void f();
}
interface H {
void f();
}
void g();

}

There are very few examples of nested interfaces. A "well-known" one is for instance Map.Entry within interface Map (in java.util).
Some will say that nested classes (or interfaces) provide a better organization of your code and allow to avoid namespace pollution. It's more a matter of taste in my opinion.
