Dice are used in many games. One die can be thrown to randomly show a value from 1 through 6. Design a Die class that can hold an integer data field for a value (from 1 to 6). Include a constructor that randomly assigns a value to a die object. For example, the following statement generates a random number between LOWEST_DIE_VALUE (which should contain the value 1) and HIGHEST_DIE_VALUE (which should contain the value 6) and assigns it to a variable. randomValue = ((int)(Math.random() * 100) % HIGHEST_DIE_VALUE + LOWEST_DIE_VALUE); Also include a method in the class to return a Die’s value. Save the class as Die.java. Write an application that randomly “throws” two dice and displays their values. Save the application as TwoDice.java. Using the Die class, write an application that randomly “throws” five dice for the computer and five dice for the player. Display the values and then, by observing the results, decide who wins based on the following hierarchy of Die values. (The computer will not decide the winner; the player will determine the winner based on observation. Later, you will learn to program the determination of the winner.) Any higher combination beats a lower one; for example, five of a kind beats four of a kind. ❯❯ Five of a kind ❯❯ Four of a kind ❯❯ Three of a kind ❯❯ A pair After you learn about decision making, you will be able to make the program determine whether you or the computer had the better roll. For now, just observe how the values change as you execute the program multiple times. Save the application as FiveDice.java.
