• Create an interface named Movable with the following methods: moveForward, moveBackward, moveUp, moveDown, and displayCoordinates. • Create a class Jet that will implement the Movable interface as follows: o The class will have two int fields to keep track of the coordinates (x, y). o The default coordinates will be (0, 0) o An overloaded constructor will allow the user to initialize the coordinates to other values. o Invoking the method moveForward will add a random int between 1-5 to x, moveBackward will subtract 1 to x, moveUp will add a random int between 1-5 to y, moveDown will subtract 1 to y, and displayCoordinates will display the current coordinates in format (x, y). • Create an application JetApp, that will test the Jet class and all its methods. • Display the coordinates each time there is a change to them.
