Define an interface class that contains two int constants, X = 5 and Y = 10 and one int method called useXY which receives no parameters.  Call your interface class XYClass

Answer:
              public interface XYClass
              {
                            public final int X = 5;
                            public final int Y = 10;

                            public int useXY( );
