有趣的java小项目------猜拳游戏

package com.aaa;

//总结：猜拳游戏主要掌握3个方面：1.人出的动作是从键盘输入的（System.in）2.电脑是随机出的（Random随机数）3.双方都要出（条件判断）
import java.util.Scanner;

public class bbb {
	public static void main(String[] args) {
		Scanner in = new Scanner(System.in);
		System.out.println("----猜拳游戏----");
		System.out.println("请出拳 (1.剪刀 2.石头 3.布)");
		int person = in.nextInt();
		int computer = (int) (Math.random() * 3) + 1;
		String Marks = "拳头";// 你出的是
		String Marks2 = "拳头";// 电脑出的是
		switch (person) {
		case 1:
			Marks = "剪刀";
			break;
		case 2:
			Marks = "石头";
			break;
		case 3:
