Clarify cross Breed Model in Java.
Cross breed legacy is a blend of single and various legacy.Since Java doesn’t bolster different legacies with classes,half and half legacy is additionally unrealistic with classes.Crossover legacy can be accomplished similarly as different legacies, that is through interfaces. We can’t expand two classes at any given moment, yet we can execute two interfaces at any given moment.We use interfaces to proclaim techniques. An interface is then stretched out by two distinctive sub interfaces. At that point a class actualizes these two sub interfaces to accomplish half and half legacy.
