java*更新*现在我的程序可以编译但不运行了?

我正在编写一个程序,提示用户在电脑上玩石头剪刀。从main方法调用int-rpsls方法时遇到问题。我不确定如何从main方法调用它,因为我需要将用户从main方法输入的值输入到rpsls方法中。以下是我到目前为止所做的,是的,它充满了错误,但我主要关心的是调用该方法

更新-我又添加了一些代码,现在程序将编译。然而,当我试图运行它时,它只是冻结。有人能帮我找到一个让程序运行的解决方案吗

import java.util.Scanner; 
public class Rpsls
{  



   public static void main (String [] args) {
      int wins = 0;
      int ties = 0;
      int losses = 0;
      int retVal = 0;
      int output = rpsls(retVal);
      //while loop 
      Scanner input = new Scanner (System.in);
      int x = input.nextInt();
         while (x > 0 && x <= 5) {
            //input gesture 

            System.out.println(" ROCK PAPER SCISSORS LIZARD SPOCK");
            System.out.println(" (1)   (2)     (3)     (4)    (5)");
            System.out.print("Enter your choice, or 0 to end: ");

            //call rpsls for inputted gesture
            int gesture = input.nextInt();
            rpsls(gesture);
            //returned values: loss, win, or tie
            if (output == -1 ) {
               losses++;
            }
               else if (output == 0) {
                  ties++;
               }
            else {
               wins++;
            }
            //count wins and losses 
            //end while loop 
            //print sum of wins and losses. 
         }
         System.out.println("You won " + wins + " games, lost " + losses + " games, and tied " + ties + " games.");

   }
