Question

need help making a rock paper scissors game that plays for 5 rounds, preferably using this format:

import java.util.Scanner;
import java.util.Random;

public class RockPaperScissors {

   public static void main(String[] args) {
       final int ROCK = 1;
       final int PAPER = 2;
       final int SCISSORS = 3;
       final int MAX_ROUNDS = 5;

       Scanner scnr = new Scanner(System.in);
       Random rand = new Random(341L);
      
       // TODO: Add variables for round, computerMaterial, playerMaterial, playerChoice, invalidChoice, etc.

       while ( /* TODO: test number of rounds played */ ) {
           System.out.println("Play! Enter: 1 (rock), 2 (paper), 3 (scissors)");
          
           // TODO: get playerChoice and set playerMaterial accordingly. A value other than 1,2, or 3, causes the
           // variable invalidChoice to be set to true.

// Start the round again if the user entered a value other than 1, 2, or 3.
           if (invalidChoice) {
               invalidChoice = false;
               continue;
           }
          
           // TODO: get the computer choice from the random number generator and set computerMaterial accordingly.

           System.out.println("Round " + round + ": computer chose " + computerMaterial
                   + " and you chose " + playerMaterial + " ");

           // Determine winner
           // If both chose the same number, println "Tie!" and a blank line
           // If you win, println "You win!" and a blank line

// TODO: Play the next round
          
       }
       System.out.println("Game over!");
   }
}

Explanation / Answer

import java.util.Scanner;
import java.util.Random;

class RockPaperScissors {
public static void main(String[] args) {
final int ROCK = 1;
final int PAPER = 2;
final int SCISSORS = 3;
final int MAX_ROUNDS = 5;
Scanner scnr = new Scanner(System.in);
Random rand = new Random();
  
// TODO: Add variables for round, computerMaterial, playerMaterial, playerChoice, invalidChoice, etc.
int round =1;
boolean invalidChoice = false;
int playerChoice,computerChoice;
String playerMaterial,computerMaterial;
playerMaterial =" ";
computerMaterial = " ";

while ( round <= MAX_ROUNDS ) {
System.out.println("Play! Enter: 1 (rock), 2 (paper), 3 (scissors)");
  
// TODO: get playerChoice and set playerMaterial accordingly. A value other than 1,2, or 3, causes the
// variable invalidChoice to be set to true.
playerChoice = scnr.nextInt();
if(playerChoice < 1 || playerChoice > 3) invalidChoice =true;
else if(playerChoice == 1) playerMaterial ="rock";
else if(playerChoice == 2)playerMaterial ="paper";
else if(playerChoice == 3)playerMaterial ="scissors";
// Start the round again if the user entered a value other than 1, 2, or 3.
if (invalidChoice) {
invalidChoice = false;
continue;
}
  
// TODO: get the computer choice from the random number generator and set computerMaterial accordingly.
computerChoice = 1 + (int)(Math.random() * 3);
  
if(computerChoice == 1) computerMaterial ="rock";
else if(computerChoice == 2) computerMaterial ="paper";
else if(computerChoice == 3) computerMaterial ="scissors";
System.out.println("Round " + round + ": computer chose " + computerMaterial
+ " and you chose " + playerMaterial + " ");
// Determine winner
// If both chose the same number, println "Tie!" and a blank line
// If you win, println "You win!" and a blank line
if(playerChoice == computerChoice)
System.out.println("Tie!");
else if(playerChoice == 1 && computerChoice ==2)
System.out.println("Player Wins");
else if(playerChoice == 2 && computerChoice ==3)
System.out.println("Computer Wins Scissors cut Paper");
else if(playerChoice == 3 && computerChoice ==1)
System.out.println("Computer Wins rock Cut Scissors");
else if(playerChoice == 2 && computerChoice ==1)
System.out.println("Player Wins");
else if(playerChoice == 3 && computerChoice ==2)
System.out.println("Player Wins Scissors cut papers");
else if(playerChoice == 1 && computerChoice ==3)
System.out.println("Player Wins Rock cuts scissors");

round++;
  
}
System.out.println("Game over!");
}
}

output:

Success time: 0.06 memory: 711680 signal:0
