Question

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 named Page that implements turn() to display "Going to the 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. Save the files as Turner.java, Leaf.java, Page.java, Pancake.java, and DemoTurners.java.

Answer 1

The question involves creating an interface called Turner with a turn() method and three classes that implement this interface with their own messages. A demo application will show these implementations in action.

Step-by-step explanation:

The student is asked to create an interface named Turner with a method named turn(). Implementations of this interface will be in classes named Leaf, Page, and Pancake, each providing their own specific output for the turn() method. An application called DemoTurners will then create objects of each class and demonstrate the use of the turn() method in each context.

To achieve this, a Java interface will be created along with three implementing classes. Each class will override the turn() method to provide a message that fits the context - 'Changing colors' for Leaf, 'Going to the next page' for Page, and 'Flipping' for Pancake. The DemoTurners application will instantiate each of these classes and call their turn() methods, effectively demonstrating the defined behaviors.
