本文实例为大家分享了Java猜拳游戏的具体代码，供大家参考，具体内容如下

先来看一下效果图:

首先我们创建一个Person类，这个类有name和score两个属性，有play这个方法，源代码如下:

package com.samoy;

public class Person {
  public String name;
  public int score;

  public Person(String name,int score) {
    this.name = name;
    this.score = score;
  }

  public String play(int i) {
    return i == 1?"剪刀":(i == 2?"石头":"布");
  }
}

接下来是主程序入口：

package com.samoy;

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

public class JavaTest {

  public static void main(String[] args) {

    int num = 0;

    System.out.println("*****************\n****猜拳,开始****\n*****************");
    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>");

    Scanner scanner = new Scanner(System.in);

    //new一个对手
    Person opponent = new Person("",0);
    int nameIndex = scanner.nextInt();
    while (true){
      if (nameIndex == 1){
        opponent.name = "刘备";
        break;
      }else if (nameIndex == 2){
        opponent.name = "孙权";
        break;
      }else if (nameIndex == 3){
        opponent.name = "曹操";
        break;
      }else {
        System.out.println("输入错误!输入对方角色<1:刘备 2:孙权 3:曹操>");
        nameIndex = scanner.nextInt();
      }
    }

    System.out.println("请输入您的姓名:");
    Scanner scanner1 = new Scanner(System.in);
    Person self = new Person(scanner1.next(),0);
    System.out.println(self.name + " VS " +opponent.name);
    System.out.println("要开始游戏吗?<y/n>");

    Scanner scanner2 = new Scanner(System.in);
    String option = scanner2.next();
    while (option.equals("y")){
      System.out.println("请出拳:1、剪刀 2、石头 3、布");
      Scanner scanner3 = new Scanner(System.in);
      int select = scanner3.nextInt();
      String result1;
      if (select!=1&&select!=2&&select!=3){
        System.out.println("输入错误!请输入出拳规则:1、剪刀 2、石头 3、布");
        select = scanner3.nextInt();
      }
      result1 = self.play(select);
      System.out.println(self.name+"出:"+result1);
      String result2 = opponent.play(new Random().nextInt(3)+1);
      System.out.println(opponent.name+"出:"+result2);

      if (result1.equals(result2)){
        System.out.println("和局");
      }else if (result1.equals("剪刀")&&result2.equals("布")||result1.equals("石头")&&result2.equals("剪刀")||result1.equals("布")&&result2.equals("石头")){
        System.out.println("你赢了! "+self.name+"赢!");
        self.score += 1;
      }else {
        System.out.println("你输了! "+opponent.name+"赢!");
        opponent.score += 1;
      }
      num++;
      System.out.println("需要进行下一局吗?<y/n>");
      option = scanner2.next();
      if (option.equals("n")){
        System.out.println("=================");
        System.out.println("共进行"+num+"局\n"+self.name+"得分为"+self.score+","+opponent.name+"得分为"+opponent.score +"\n");
        if (self.score>opponent.score){
          System.out.println(self.name+"赢!"+self.name+"好棒!");
        }else if (self.score == opponent.score){
          System.out.println("平局!");
        }else {
          System.out.println(opponent.name+"赢!"+self.name+"笨蛋!");
        }
        System.out.println("感谢你的使用!");
      }else if (!option.equals("y")){
        System.out.println("输入错误,请重新输入!");
        System.out.println("需要进行下一局吗?<y/n>");
        option = scanner2.next();
      }
    }
  }
}
