Create an interface MyInterface which contains only one default method, int CountNonZero(int n). CountNonZero(n) is a recursive method that returns the number of non-zero digits in a given integer n. For example, if n=20203 then CountNonZero(n) should return 3. Create an abstract class MyClass which implements MyInterface and contains an abstract method double power(int n, int m). Use an anonymous class to implement this method so that it returns nm. For example, if n = 5, m =2 then power(n, m) should return 25.0. In the driver program, print the value of these two methods for the example data.
