Create an interface named Turner, with a single method named turn(). Create a class named Leaf that implements turn() to display "Changing colors". Create a class name Page that implements turn() to display "Going to next page". Create a class named Pancake that implements turn() to display "Flipping". Write an application named DemoTurners that creates one object of each of these class types and demonstrates the turn() method for each class. Also, think of two more objects that use turn(), create classes for them, and then add objects to the DemoTurners application
