请用java编写一个石头剪刀布的程序

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

        sc = new Scanner(System.in);
        rad = new Random();
        while(true) {
            System.out.println("~~~~~~~~~~~~剪刀石头布游戏，输入E可以退出~~~~~~~~~~~");
            System.out.println("请选择你要出什么？Z——剪刀，X——石头，C——布");
            String command = sc.nextLine();
            int playerFinger = getValue(command);
            if(playerFinger == -1) {
                break;

            int cpuFinger = rad.nextInt(3);
            System.out.println("计算机出的是" + FINGERS[cpuFinger]);
            int result = playerFinger - cpuFinger;
            if(0 == result) {

            }
        }
         
        System.out.println("游戏结束！\r\n游戏统计次数");
        System.out.println(String.format("赢：%d\r\n输：%d\r\n平局：%d", win, loose, draw));
    }
