What is the solution for this?

Programming Activity 2: Using Polymorphism Programming Activity, you will complete the implementation of the Ihis nth Hare race. The Tortoise runs a slow and steady race, while e runs in spurts with rests in between. Figure 10.14 shows a sample the Hare f the race. In this figure, we show only one tortoise and one hare; uh over using polymorphism we can easily run the race with any number however, and combination of tortoises and hares. The class hierarchy for this Programming Activity is shown in Figure 10.15. code for the Racer class, which is the superclass of the Tortoise and re classes, is shown in Example 10.20. The Racer class has three instance variables (lines 10-12): a String ID, which identifies the type of racer; and positions, both of which are ints. The class has the usual construc- tors, as well as accessor and mutator methods for the x and y positions and ID. These instance variables and methods are common to all racers, so we Ha
