Java面向对象之猜拳游戏，供大家参考，具体内容如下
1 要求
与电脑进行猜拳并记录分数。
2 Computer.java 源代码(电脑自动随机出拳)
public class Computer {
public void Fingers(int index) {
String[] fingers = {"石头", "剪刀", "布"};
System.out.println("电脑出拳：" + fingers[index]);
}
}3 Game.java 源代码(实现主要功能的类)
import java.util.Random;
import java.util.Scanner;
public class Game {
public void initial(){
//页面
Scanner scanner = new Scanner(System.in);
System.out.println("-------------------欢迎进入游戏界面-------------------");
System.out.println();
System.out.println(" ***********************");
System.out.println(" *******猜拳，开始！******");
System.out.println(" ***********************");
System.out.println("出拳规则：0.石头 1.剪刀 2.布");
//输入姓名
System.out.print("请输入你的姓名：");
String name = scanner.next();
System.out.println(name+" VS 汶老板 对战");
//判断是否开始
System.out.print("要开始吗？（输入yes/no）:");
String b =scanner.next();
int count = 0;
int usercount=0;
int computercount=0;
while (b.equals("yes")){
//统计对战次数
count++;
//玩家出拳
System.out.print("请出拳 0.石头 1.剪刀 2.布（输入相对应的数字）：");
int a = scanner.nextInt();
String [] fingers = {"石头","剪刀","布"};
System.out.println("你出拳："+fingers[a]);
//电脑随机出拳
Random random = new Random();
int index = random.nextInt(3);
Computer computer = new Computer();
computer.Fingers(index);
//判断输赢
if ((a == 0 && index == 1)||(a == 1 && index == 2)||(a == 2 && index == 0)) {
System.out.println("结果说：恭喜你，你赢得了！");
usercount = usercount+1;
}else if ((a == 0 && index == 2)||(a == 1 && index == 0)||(a == 2 && index == 1)){
System.out.println("结果说：很抱歉，你输了！");
computercount = computercount+1;
}else{
System.out.println("结果说：平局！");
}
//是否进行下一局
System.out.print("是否继续进行下一局！（输入yes/no）");
b = scanner.next();
}
//总结
System.out.println("----------------------总结---------------------");
System.out.println(name+" VS 汶老板");
System.out.println("对战次数："+count);
System.out.println("姓名\t\t得分");
System.out.println("汶老板\t"+computercount);
System.out.println(name+"\t"+usercount);
String i = computercount>usercount?"很遗憾，你输了本场比赛！":computercount<usercount?"恭喜你，你赢得了本场比赛！":"平局！";
System.out.println(i);
}
}3 Client.java 源代码(测试类)
public class Client {
public static void main(String[] args) {
Game game = new Game();
game.initial();
}
}4 结果截图
