Number 14.29

Modify the ClockPane class with three new Boolean properties-hourHandVisible, minuteHandVisible, and secondHandVisible-and their associated accessor and mutator methods. You can use the set methods to make a hand visible or invisible. Write a test program that displays only the hour and minute hands. The hour and minute values are randomly generated. The hour is between 0 and 11, and the minute is either 0 or 30, as shown in Figure 14.52b. (Game: bean machine) Write a program that displays a bean machine introduced in Programming Exercise 7.21, as shown in Figure 14.52c
