Question

Write a java program that plays the popular scissor-rock-paper game. (A scissor can cut a paper, a rock can break a scissor, and a paper can cover a rock.) The program randomly generates a number 0, 1, or 2 representing scissor, rock, and paper. The program prompts the user to enter a number 0, 1, or 2 and displays a message indicating whether the user or the computer wins, loses, or draws. Allow the user to continue playing or quit.

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

public class RockPaperScissors {
   public final static String ONE = "rock";
   public final static String TWO = "paper";
   public final static String THREE = "scissors";

   public static void main(String[] args) {
       String ch = "y";

       while (ch.equalsIgnoreCase("y")) {
           int cch = getComputerChoice();
           int uch = getUserChoice();
           findWinner(cch, uch);
           System.out.println("Do you want to continue (Y/N)");
           ch = sc.nextLine();
       }
       sc.close();
   }

  

   private static void findWinner(int aCch, int aUch) {
       // checking winner based on user and computer choice
       if (aCch == 1 && aUch == 3)
           System.out.println(ONE + " wons");
       else if (aCch == 3 && aUch == 1)

       else if (aCch == 2 && aUch == 1)
           System.out.println(TWO + " wons");
       else

   }

   private static int getComputerChoice() {
       // generating the random from 1 to 3
       int n = new Random().nextInt(3) + 1;
