An interface can extend other interfaces, just as a class
can extend or subclass another class. However, whereas a
class can extend only one other class, an interface can
extend any number of interfaces. The interface declaration
includes a comma-separated list of all the interfaces that
it extends.

interface Sameinterface1 { }

interface Sameinterface2 { }

interface Sameinterface3 { }
....

...
interface SameinterfaceN { }

interface Sameinterface4 extends
Sameinterface1 ,Sameinterface2 ,...Sameinterface3 ,
SameinterfaceN {

}
