一、猜拳游戏：

package com.lovo;

import java.util.Scanner;

public class GuessGesticulate {

    public static void main(String[] args) {

        boolean goon = true;
        int me = 0;
        Scanner sc = new Scanner(System.in);

        Gesticulate ge = new Gesticulate();

        do {
            do {
                System.out.print("1、石头   2、剪刀   3、布   你想出哪个？");
                if (sc.hasNextInt()) {
                    me = sc.nextInt();
                } else {
                    System.out.print("无效输入");
                    sc.nextLine();
                }
            } while (me < 1 && me > 3);

            goon = ge.contrast(me);

            System.out.println(ge.getHint());

        } while (goon);
    }
}

二、猜数字游戏：

package com.lovo;

public class Gesticulate {
    private int systemGesticulate = 0;
    private String hint = "";

    public Gesticulate(){
        this.random();
    }

    public boolean contrast(int gesture) {
        if(gesture == systemGesticulate){
            random();
            if(gesture == 1){
                hint="电脑也是石头，平局！！！";
            }else if (gesture == 2){
                hint="电脑也是剪刀，平局！！！";
            }else{
                hint="电脑也是布，平局！！！";
            }
        }else if(systemGesticulate == 1){
            if(gesture == 3){
                hint ="电脑是石头,你赢了";
                return false;
            }else if(gesture == 2){
                hint ="电脑是石头,你输了";
                return false;
            }
        }else if(systemGesticulate == 2){
            if(gesture == 3){
                hint ="电脑出的剪刀,你输了";
                return false;
            }else if(gesture == 1){
                hint ="电脑是剪刀,你赢了";
                return false;
            }
        }else if(systemGesticulate == 3){
            if(gesture == 1){
                hint ="电脑是布,你输了";
                return false;
            }else if(gesture == 2){
                hint ="电脑是布,你赢了";
                return false;
            }
        }
        return true;
    }

    public void random(){
        this.systemGesticulate =(int) ( Math.random()*3+1 );
    }

    public String getHint(){
        return hint;
    }
}
