简单的java小游戏-石头剪刀布（课程设计/课后习题）

石头剪刀布-简单的java小游戏

一、案例分析

隔壁秃头今天发来一个题目，叫我们用Java给他我们做一个小游戏，具体内容有：

1. 实现传统益智游戏：石头剪刀布
2. 用户进入OS,首先输入自己的游戏名称
3. 选择一位对手进行比拼
4. 每进行一轮比拼就记录结果，方便最后计分
5. 最后根据胜场数评出最终获胜方

二、结构设计

对规则做了如下规定：

• 数字1：剪刀、数字2：石头、数字3：布
  构建：

• Dos:主类

• User:用户类
  1）用户名
  2）得分

• Opponent：对手类
  1）对手名
  2）得分
  3）挑战难度（0~1）

三、运行结果

四、具体代码

        ops[1]=new Opponent("司马懿", 0.5);
        ops[2]=new Opponent("曹操", 0.4);
        ops[3]=new Opponent("刘备", 0.3);
        ops[4]=new Opponent("孙权", 0.1);
