用java编一个程序，实现两个人玩“石头、剪刀、布”，要求用枚举类型定义石头、剪刀、布

public class Test {
public enum Hand{//猜拳枚举
ROCK,SCISSORS,PAPER;
public static Hand getHand(int index){
Hand hand = null;
switch (index) {
case 0:
hand = Hand.ROCK;
break;
case 1:
hand = Hand.SCISSORS;
break;
case 2:
hand = Hand.PAPER;
break;
default:
hand = Hand.ROCK;
break;
}
return hand;
}
}

public static void main(String[] args) {
//两个人猜拳5次
for (int i = 0; i < 5; i++) {
Hand hand1 = Hand.getHand((int)(Math.random()*3));
Hand hand2 = Hand.getHand((int)(Math.random()*3));
judge(hand1, hand2);
}

}

private static void judge(Hand hand1,Hand hand2){
if(hand1 == Hand.ROCK){
if(hand2 == Hand.ROCK){
System.out.println("第一个出拳头，第二个出拳头，平局");
}else if(hand2 == Hand.SCISSORS){
System.out.println("第一个出拳头，第二个出剪刀，第一个赢");
}else if(hand2 == Hand.PAPER){
System.out.println("第一个出拳头，第二个出布，第二个赢");
}
}else if(hand1 == Hand.SCISSORS){
if(hand2 == Hand.ROCK){
System.out.println("第一个出剪刀，第二个出拳头，第二个赢");
}else if(hand2 == Hand.SCISSORS){
System.out.println("第一个出剪刀，第二个出剪刀，平局");
}else if(hand2 == Hand.PAPER){
System.out.println("第一个出剪刀，第二个出布，第一个赢");
}
}else if(hand1 == Hand.PAPER){
if(hand2 == Hand.ROCK){
System.out.println("第一个出布，第二个出拳头，第一个赢");
}else if(hand2 == Hand.SCISSORS){
System.out.println("第一个出布，第二个出剪刀，第二个赢");
}else if(hand2 == Hand.PAPER){
System.out.println("第一个出布，第二个出布，平局");
}
}
}
}应该不是最优解决办法，先这么着把
追问大神谢谢啦可是得是从键盘输入拳头追答main函数里面写个scanner， 接收输入0：石头 1：剪刀 2布 不就行了追问对，我已经改了追答请采纳
