项目名称

猜拳小游戏

项目描述

玩家与电脑进行猜拳游戏，玩家行为采用输入方式，电脑行为采用随机形式。

代码实现

测试类

public class Test {
  public static void main(String[] args) {
    Game game = new Game();
    game.start();
  }
}

主类：实现主方法

public class Game {
  private People people;
  private Computer computer;
  public Game(){
    people = new People("zs");
    computer = new Computer("computer");
  }
  public void start(){
    boolean flag = true;
    while (flag) {
      System.out.println("开始游戏：");
      int count = 0;
      while (count < 3) {
        String peopleFist = people.doFist();
        String comFist = computer.doFist();
        //people赢
        if (peopleFist.equals("石头") && comFist.equals("剪刀") ||
            peopleFist.equals("剪刀") && comFist.equals("布") ||
            peopleFist.equals("布") && comFist.equals("石头")) {
          System.out.println(people.getName() + "赢了");
          people.addScore(1);
        } else if (peopleFist.equals("石头") && comFist.equals("石头") ||
            peopleFist.equals("剪刀") && comFist.equals("剪刀") ||

        } else if (peopleFist.equals("石头") && comFist.equals("布") ||
            peopleFist.equals("剪刀") && comFist.equals("石头") ||
            peopleFist.equals("布") && comFist.equals("剪刀")) {
          System.out.println(computer.getName() + "赢了");
          computer.addScore(1);
        }
        count++;
      }
      if (people.getScore() > computer.getScore()) {
        System.out.println(people.getName() + "赢了 " + people.getScore() + ":" + computer.getScore());
      } else if (people.getScore() == computer.getScore()) {
        System.out.println("平局");
      } else if (people.getScore() < computer.getScore()) {
        System.out.println(computer.getName() + "赢了 " + computer.getScore() + ":" + people.getScore());
      }
      System.out.println("是否开始新游戏：");
      Scanner scanner = new Scanner(System.in);
      String str = scanner.next();
      if (str.equals("否")) {
        flag = false;
      }else {
        people.setScore();
        computer.setScore();
      }
    }
  }
}

玩家

public class People {
  private String name;
  private int score;
  public People(String name){
    this.name = name;
    score = 0;
  }
  public String getName(){
    return name;
  }
  public void addScore(int score){
    this.score += score;
  }
  public int getScore(){
    return score;
  }
  public int setScore(){
    this.score = 0;
    return score;
  }
  public String doFist(){
    System.out.println("请出拳：");
    Scanner scanner = new Scanner(System.in);
    String fist = scanner.next();
    return fist;
  }
}

电脑

public class Computer {
  private String name;
  private int score;
  public Computer(String name){
    this.name = name;
    score = 0;
  }
  public String getName(){
    return name;
  }
  public void addScore(int score){
    this.score += score;
  }
  public int getScore(){
    return score;
  }
  public int setScore(){
    this.score = 0;
    return score;
  }
  public String doFist(){
    Random random = new Random();
    int n = random.nextInt(3);
    String fist;
    if(n == 0){
      fist = "石头";
    }else if(n == 1){
      fist = "剪刀";
    }else {
      fist = "布";
    }
    System.out.println("对方出的是："+fist);
    return fist;
  }
}
