java学习之简单石头剪刀布游戏

有个人Tom设计他的成员变量，成员方法，可以电脑猜拳。电脑每次都会随机生成0，1，2，其中0代表石头，1代表剪刀，2代表布，并要显示Tom的输赢次数（清单）。

Tom类

class Tom{//玩家出拳的类型int tomGuessNum;//0,1,2//电脑出拳的类型int comGuessNum;//0,1,2//玩家赢的次数int winCountNum;//比赛的次数int count = 1;/*电脑随机生成猜拳的数字的方法*/public int computerNum(){Random r = new Random();comGuessNum = r.nextInt(3);//方法 返回0-2随机数return comGuessNum;}/*设置玩家猜拳的数字的方法*/public void setTomGuessNum(int tomGuessNum){if (tomGuessNum>2||tomGuessNum<0) {//抛出一个异常throw new IllegalArgumentException("数字输入有误");}this.tomGuessNum = tomGuessNum;}public int getTomGuessNum(){return tomGuessNum;}/*比较猜拳结果*/public String vsComputer(){if (tomGuessNum == 0 && comGuessNum == 1) {return "你赢了";}else if(tomGuessNum == 1 && comGuessNum == 2){return "你赢了";}else if(tomGuessNum == 2 && comGuessNum == 0){return "你赢了";}else if(tomGuessNum == comGuessNum){return "平手";}else{return "你输了";}}/*记录玩家赢的次数*/public int winCount(String s){count++;if (s.equals("你赢了")) {winCountNum++;}return winCountNum;}
}
