人机猜拳项目

import java.util.Scanner;

public class demo1 {

    /**
     * @param args
     */
    public static void main(String[] args) {
        // TODO Auto-generated method stub
一:选择定义该项目中所需要的变量:

        Scanner input = new Scanner(System.in);
        String name;
        String dianname = null;
        int choose;//选择
        int myfen;//本人得分
        String kai;//开始
        int dianfen;//电脑得分
        int my;//本人
        int dian;//电脑
        int count = 0;//对战次数
        int ying = 0;//本人赢得次数
        int shu = 0;//本人输的次数
  二:选择定义初始变量:
        System.out.println("---------欢迎进入游戏世界------------");
        System.out.println("***************************");
        System.out.println("\t\t**猜拳,开始**");
        System.out.println("\t\t*****************");
        boolean con = false;
三:选择本人要选择的对抗角色和输出的内容:
        do {
            con = false;
            System.out.println("出拳规则:1:剪刀 2:石头3:布");

            System.out.println("请选择对方角色(1:刘备 2:孙权 3:曹操)");
            choose = input.nextInt();
            System.out.println("请输入姓名");
            name = input.next();
            switch (choose) {
            case 1:
                dianname = "刘备";
                System.out.println(name + "VS" + dianname+"对战");
                break;
            case 2:
                dianname = "孙权";
                System.out.println(name + "VS" + dianname+"对战");
                break;
            case 3:
                dianname = "曹操";
                System.out.println(name + "VS" + dianname+"对战");
                break;
            default:
                System.out.println("输入错误,请从新输入");
                con = true;
            }
        } while (con);
        
            
        System.out.println("要开始吗(y/n)");
        kai = input.next();
        while (kai.equals("y")) {
            do{  
                con =false;
四:本人所输出的内容与人机所输出的内容的对抗与之比较:
            System.out.println("请出拳(1.拳头 2.剪刀 3.布)");
            my = input.nextInt();
            switch (my) {
            case 1:
                System.out.println(name + "出拳:石头");
                break;
            case 2:
                System.out.println(name+"出拳:剪刀");
                break;
            case 3:
                System.out.println(name+"出拳:布");
                break;
            default:
                System.out.println("输入错误,请从新输入");
                con = true;
            }
            }while(con);
                
            
            dian = (int) (Math.random() * 3 + 1);
            switch (dian) {
            case 1:
                System.out.println(dianname+" 出拳:石头 ");
                break;
            case 2:
                System.out.println(dianname+" 出拳:剪刀");
                break;
            case 3:
                System.out.println(dianname+" 出拳:布");
                break;
            }
六:不同的情况所显示的不同结果
            if (my == 1 && dian == 1 || my == 2 && dian == 2 || my == 3
                    && dian == 3) {
                System.out.println("和局,真衰,嘿嘿,等着瞧吧");
            } else if (my == 1 && dian == 2 || my == 2 && dian == 3 || my == 3
                    && dian == 1) {
                System.out.println("恭喜你赢了");
                ying++;
            } else {
                System.out.println("你输了,真笨");
                shu++;
            }
            count++;
            System.out.println("要继续吗(y/n)");
            kai = input.next();
        }
        System.out.println(name + "VS" + dianname);
        System.out.println("对战次数" + count);
        System.out.println("姓名/t得分");
        System.out.println(name+"\t"+ying);
        System.out.println(dianname+"\t"+shu);
        if (ying > shu) {
            System.out.println("赢了");
        } else if (ying < shu) {
            System.out.println("输了");

        } else {
            System.out.println("和局");
        }

    }
}
注意:
1>要清楚该项目的循环内容,并使用正确的循环方法;
