There should be an equal chance for any one of the eight responses to come up. The program should ask the user if he or she would like to repeat the program and loop if the user opts to repeat. Random number generation is discussed in Chapter 6, but for this program you can use the following line of code to generate a random number between 1 and 8:
int num = (int) (Math.random() * 8) + 1;
