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") || peopleFist.equals("布") && comFist.equals("布")) { System.out.println("平局"); } 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; }}
