Java Program Chapter 5. PC #17. Rock, Paper, Scissors Game (page 317) Write a program that lets the user play the game of Rock, Paper, Scissors against the computer. The program should work as follows. 1. Add the following two lines to the beginning of your main method. This will allow your computer choices match with the test cases here in HyperGrade. long seed = Long.parseLong(args[0]); Random random = new Random(seed); 2. When the program begins, a random number in the range of 0 through 2 is generated. If the number is 0, then the computer has chosen rock. If the number is 1, then the computer has chosen paper. If the number is 2, then the computer has chosen scissors. (Do not display the computer choice yet.) 3. The user enters his or her choice of "rock", "paper", or "scissors" at the keyboard. You should use 1 for rock, 2 for paper, and 3 for scissors. Internally, you can store 0, 1, and 2 as the user choice, to match with the above schema. 4. Both user and computer choices are displayed. 5. A winner is selected according to the following rules: If one player chooses rock and the other player chooses scissors, then rock wins. (The rock smashes the scissors.) If one player chooses scissors and the other player chooses paper, then scissors wins. (Scissors cuts paper.) If one player chooses paper and the other player chooses rock, then paper wins. (Paper wraps rock.) If both players make the same choice, then it is a draw. If you prefer, you can use circular addition for selecting a winner. For example if computer_choice + 1 modulo 3 is equal to human_choice, then the user wins. 6. Then the user is prompted for continuing the game. If the user selects "yes" or "y" (case insensitive) then another round is played. If the user selects "no" or "n", then the program exits. Make sure to divide the program into methods that perform each major task. As always, make sure you only have one Scanner object linked to the keyboard. Also, you should only have one random number generator (shown above).   Here is a working code but please fix it so it will in Hypergrade which as all the test casses.

Chapter 5. PC #17. Rock, Paper, Scissors Game (page 317)
Write a program that lets the user play the game of Rock, Paper, Scissors against the computer. The program should work as follows.
1. Add the following two lines to the beginning of your main method. This will allow your computer choices match with the test cases here in HyperGrade.
long seed = Long.parseLong(args[0]);
Random random = new Random(seed);
2. When the program begins, a random number in the range of 0 through 2 is generated. If the number is 0, then the computer has chosen rock. If the number is 1, then the computer
has chosen paper. If the number is 2, then the computer has chosen scissors. (Do not display the computer choice yet.)
3. The user enters his or her choice of "rock", "paper", or "scissors" at the keyboard. You should use 1 for rock, 2 for paper, and 3 for scissors. Internally, you can store 0, 1, and 2 as the user choice, to match with the above schema.
4. Both user and computer choices are displayed.
5. A winner is selected according to the following rules:
If one player chooses rock and the other player chooses scissors, then rock wins. (The rock smashes the scissors.)
If one player chooses scissors and the other player chooses paper, then scissors wins. (Scissors cuts paper.)
If one player chooses paper and the other player chooses rock, then paper wins. (Paper wraps rock.)
If both players make the same choice, then it is a draw.
If you prefer, you can use circular addition for selecting a winner. For example if computer_choice + 1 modulo 3 is equal to human_choice, then the user wins.
6. Then the user is prompted for continuing the game. If the user selects "yes" or "y" (case insensitive) then another round is played. If the user selects "no" or "n", then the program exits.
Make sure to divide the program into methods that perform each major task. As always, make sure you only have one Scanner object linked to the keyboard. Also, you should only have one random number generator (shown above).
