Question

**IN JAVA**

Make a Game

-Game Strategy

The program and the user alternate turns, picking up one, two, or three straws on each turn.

The program goes first.

The player to pick up the last straw loses.

-Game process

Your program should start by generating and displaying a random integer (which represents the number of straws) between 10 and 20 inclusive.

If this number is 1 more than a multiple of 4, add 1. For example, if the random integer is 20, then start with 20 straws. However, if the random integer is 17 (which is 1 more than a multiple of 4), start with 18.

On a user’s turn, your program should prompt for, read in, and process the user’s input (which should be 1, 2, or 3—the number of straws to pick up).

On the program’s turn, it should determine its move by generating a random number between 1 and 3. At the end of each game, your program should display

Do you want to play another game?

It should then read in the user’s yes/no response, and proceed accordingly. Use a do­while loop to control the repetition of games.

If either a user’s move or the program’s move is greater than the number of straws, then all the remaining straws should be picked up, resulting in a loss. For example, if there are 2 straws left, and the user’s move is 3, the remaining 2 straws should be picked up, causing the user to lose.

Java Program:

import java.util.Random;

import java.util.Scanner;

public class StrawsGame {

       public static void main(String[] args)

       {

              Random rand = new Random(); //random number generator

              Scanner sc = new Scanner(System.in); //scanner object

             

              String choice; //to hold user's choice

              //loop till user wants to quit

              do

              {

                     int straws = rand.nextInt(11) + 10; //generate straws 10-20

                     //if straws are 1 more than a multiple of 4

                     if(straws%4 == 1)

                           straws = straws + 1; //add 1

                     System.out.println("Total straws are "+straws); //print straws

                     int user, program; //to hold straws picked

                     String winner = "Program"; //assume winner is program

                     //loop till strwas becomes 0

                     while(straws > 0)

                     {

                           System.out.println("\n"+straws+" straws are remaining."); //strwas remaining

                           System.out.print("Enter straws to pick: "); //ask user to pick

                           user = sc.nextInt(); //get value

                           sc.nextLine(); //ignore \n

                           //if more than straws

                           if(straws <= user)

                           {     

                                  straws = 0; //set straws to 0

                                  winner = "Program"; //declare Program as winner

                           }

                           //otherwise subtract user choice

                           else

                                  straws = straws - user;

                           program = rand.nextInt(3) + 1; //programs choice

                           //if more than straws

                           if(straws <= program)

                           {     

                                  program = straws; //set value to straws

                                  straws = 0; //set straws to 0

                                  winner = "User"; //declare user as winner

                           }

                           //otherwise remove program's choice

                           else

                                  straws = straws - program;

                           //print strwas picked by program

                           System.out.println("Program picked "+program+" straws.");

                          

                     }

                     //print winner

                     System.out.println("\nWinner is "+ winner);

                     System.out.print("\nDo you want to continue?(yes/no)"); //ask to continue or not

                     choice = sc.nextLine(); //get choice

                     choice = choice.toLowerCase();

              }while("yes".equals(choice) || "y".equals(choice));

             

              sc.close();

       }

}
