Beginnings of a paper-rock-scissors game.

Paper-rock-scissors is a game often used to make decisions. There are two players. Each player secretly chooses either, paper, rock or scissors. At the count of three, each player reveals what they have chosen.

The winner of the game is determined this way:

paper beats rock (because paper covers rock)

rock beats scissors (because rock crushes scissors)

scissors beat paper (because scissors cut paper)

If the two players choose the same item, it is a tie.

Write a program to play five hands of this game. The computer will play against the human user.

Ask the user to enter his/her choice and the computer will randomly pick a choice. Then the program will determine who wins or if it is a tie and print a message to the screen. After a hand is played. Print who wins the hand. After five hands, print how many each player

(computer and human) won.

Here is sample output:

Enter your choice (P, R, or S) (user enters S)

The computer chose rock, you chose scissors so the computer won!

Use rhe Random methods we used in lecture:

Import java.util.* Random rng = new Random( ); //to get an int in range of 0 through 4: num = rng.nextInt(5);

Answer 1

JAVA PROGRAM:

import java.util.*;
class Game
{
public static void main(String arg[])
{
Scanner sc=new Scanner(System.in);
int i,scoreU=0,scoreS=0;
for(i=0;i<5;i++)
{
System.out.print("User:");
String a=sc.nextLine();
if(a.equals("P")||a.equals("S")||a.equals("R"))
{
Random r=new Random();
int n=r.nextInt(5);
n%=3;
if(n==0)
{
System.out.println("System:P");
}
else if(n==1)
{
System.out.println("System:S");
}
else if(n==2)
{
System.out.println("System:R");
}
if((a.equals("P")&&n==2)||(a.equals("S")&&n==0)||(a.equals("R")&&n==1))
{
scoreU++;
}
else if((a.equals("P")&&n==1)||(a.equals("S")&&n==2)||(a.equals("R")&&n==0))
{
scoreS++;
}
}
else
{
System.out.println("Wrong Choice");
}
}
System.out.println("User Score:"+scoreU);
System.out.println("System Score:"+scoreS);
if(scoreU>scoreS)
{
System.out.println("Winner is User");
}
else if(scoreU<scoreS)
{
System.out.println("Winner is System");
}
else
{
System.out.println("Match Tie");
}
};
};
SAMPLE INPUT OUTPUT:

Hand 1
User:R
System:R
Hand 2
User:S
System:P
Hand 3
User:P
System:S
Hand 4
User:S
System:P
Hand 5
User:R
System:S
User Score:3
System Score:1
Winner is User
