WAP a program that illustrates interface inheritance. Create two interface p1 and p2 . create Interface p which extends p1 and p2 and then create interface p12 which extends p12. Each interface declare one constants and one method. Create class Q which implements p12 and define all the methods of interface which displays value of constants
