This might help you You should get a compile error since your interface is called irewhzz but you invoke irewhizz.
But I'm guessing that it's just a copy paste error, right?

around this issue This sounds like a basic polymorphism question to me. Think about what are you actually trying to do- for instance, a line has 2 points (X1/Y1, and X2/Y2). An ellipse (an oblong circle) has no such property- it has a width, maybe, and a height, and possibly an X and Y coordinates (or a position property).
I am guessing that you are attempting to adjust the bounds and/or location of the shape when the user is dragging it with the mouse. In this case, the operations that you need to define for the shape depend on what kind of shape it is. For a line, you need to write a method that adjusts X2 and Y2 (or whatever). For an ellipse, you will probably need another method that adjusts shapes that have width, height, left, and top properties. Then you just need to determine which one to call depending on which kind of shape you are dealing with.

this one helps. The problem that you're having about accessing base class stuff in a class template, is a FAQ item.
Rather then quoting the whole FAQ item here, I just link to it: that's your answer.
If Multiple inheritance has the diamond pattern issue, then Multiple Interfaces should also have the same issue

To fix this issue A clash between two interfaces occurs when two methods have the same parameters but a different return type.
code :
public class MultipleInterfaceClash {

    public interface Foo {
        String baz(int a, String x);

    public interface Bar {
        Double baz(int a, String x);

    public class Confused implements Foo, Bar {

        // Compile error: The return type is incompatible with
        // MultipleInterfaceClash.Foo.baz(int, String)
        public Double baz(int a, String x) {
            return null;

wish helps you This is a famous multiple inheritance problem called "The Diamond Problem".
You need concepts such as virtual base classes - "Virtual Inheritance" (C++).

I wish this help you if you use Object.getOwnPropertyDescriptors(Object.getPrototypeOf(q)) you should see the inherited properties from p. If you check equality with Object.getPrototypeOf(), the prototype of q should be equal to p.
