Question

Write java program that implements a game in which the computer plays against the human.

GAME OF CHANCE RULES:

1. Both players start with a score of 0.
2. The game lasts at most 10 rounds.
3. During each round, each player throws a fair virtual die.
4. The player who threw the higher number gains the sum of points thrown by both players during that round.
   • Example: If computer throws '5' and human throws '3', computer gains 8 points.
5. If both players throw the same number, both lose the sum of points thrown that round.
   • Example: If computer throws '5' and human also throws '5', they each lose 10 points.
6. If one of the player has a negative number of points, the game ends.
7. If at any point after the third round one of the players has more than 5 times as many points as the other, the game ends.

Answer 1

// Java program to simulate a game of chance between 2 players

import java.util.Random;

import java.util.Scanner;

public class GameOfChance {

       // method to return the result of rolling a fair virtual die

       public static int dieRoll()

       {

             Random ran = new Random();

             return(ran.nextInt(6)+1);

       }

      

      

       public static void main(String[] args) {

            

             int rounds = 0;

             final int MAX_ROUNDS = 10;

             int player1_score =0, player2_score=0;

             int player1_die, player2_die;

             Scanner scan = new Scanner(System.in);

             // loop continues at most MAX_ROUNDS rounds

             while(rounds < MAX_ROUNDS)

             {

                    rounds++;

                    // get the die rolls for both the players

                    player1_die = dieRoll();

                    player2_die = dieRoll();

                    System.out.println("ROUND: "+rounds+"\nPlayer1 Score : "+player1_score+" Player2 Score : "+player2_score);

                    System.out.println("Player 1 rolls : "+player1_die+" Player 2 rolls : "+player2_die);

                    // update the scores of the players

                    if(player1_die > player2_die)

                    {

                           player1_score += player1_die+player2_die;

                    }else if(player1_die < player2_die)

                    {

                           player2_score += player1_die+player2_die;

                    }else

                    {

                           player1_score -= (player1_die+player2_die);

                           player2_score -= (player1_die+player2_die);

                    }

                   

                    // check if game is over or not

                    if((player1_score < 0) || (player2_score < 0))

                           break;

                    if(rounds > 3 && ((player1_score > 5*player2_score) || (player2_score > 5*player1_score)))

                           break;

                    System.out.println("Enter any key to continue... ");

                    scan.nextLine();

             }

            

             scan.close();

             System.out.println("\nPlayer1 Score : "+player1_score+" Player2 Score : "+player2_score);

             // determine the winner

             if(player1_score == player2_score)

                    System.out.println("Its a tie");

             else if(player1_score > player2_score)

                    System.out.println("Player 1 wins");

             else

                    System.out.println("Player 2 wins");

       }

}

//end of program

Output:
