Java实现的剪刀石头布游戏示例

本文实例讲述了java实现的剪刀石头布游戏。分享给大家供大家参考，具体如下：

choiceanswer.java

public class choiceanswer {
    string texts[] = { "石头", "剪刀", "布" };
    int value; // 【1】石头\t【2】剪刀\t【3】布
    string gettext() {
        return texts[value - 1];
    }
    choiceanswer(int value) {
        this.value = value;
    }
    /**
     * 返回0表示平手，返回1表示赢，返回-1表示输
     */
    int compto(choiceanswer c) {
        if (value == c.value) {
            return 0;
        }
        if (value + 1 == c.value || (value == 3 && c.value == 1)) {
            return 1;
        }
        return -1;
    }
}

game.java

import java.util.scanner;
public class game {
    void p(string s) {
        system.out.println(s);
    }
    void showwelcome() {
        p("欢迎使用······");
        p("请选择：【1】石头\t【2】剪刀\t【3】布");
    }
    @suppresswarnings("resource")
    choiceanswer getuserchoice() {
        scanner sc = new scanner(system.in);
        int userchoice = integer.parseint(sc.nextline());
        while (userchoice < 1 || userchoice > 3) {
            p("你输入的不正确！请重新输入！");
            userchoice = integer.parseint(sc.nextline());
        }
        return new choiceanswer(userchoice);
    }
    choiceanswer getcomputerchoice() {
        int computerchoice = (int) ((math.random() * 3) + 1);
        return new choiceanswer(computerchoice);
    }
    void showresult(choiceanswer userchoice, choiceanswer computerchoice) {
        int result = userchoice.compto(computerchoice);
        if (result == 0) {
            system.out.println("平手,您和电脑均选择了：" + userchoice.gettext());
        } else if (result == 1) {
            system.out.println("恭喜,您赢了！您选择了：" + userchoice.gettext()
                    + ";   电脑选择了：" + computerchoice.gettext());
        } else {
            system.out.println("对不起,您败了！您选择了：" + userchoice.gettext()
                    + ";电脑选择了：" + computerchoice.gettext());
        }
    }
    void start() {
        showwelcome();
        choiceanswer userchoice = getuserchoice();
        choiceanswer computerchoice = getcomputerchoice();
        showresult(userchoice, computerchoice);
    }
    public static void main(string a[]) {
        system.out.println("测试结果：");
        new game().start();
    }
}
