代碼實現

測試類

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

主類：實現主方法

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('開始游戲：'); int count = 0; while (count < 3) {String peopleFist = people.doFist();String comFist = computer.doFist();//people贏if (peopleFist.equals('石頭') && comFist.equals('剪刀') || peopleFist.equals('剪刀') && comFist.equals('布') || peopleFist.equals('布') && comFist.equals('石頭')) { System.out.println(people.getName() + '贏了'); people.addScore(1);} else if (peopleFist.equals('石頭') && comFist.equals('石頭') || peopleFist.equals('剪刀') && comFist.equals('剪刀') || peopleFist.equals('布') && comFist.equals('布')) { System.out.println('平局');} else if (peopleFist.equals('石頭') && comFist.equals('布') || peopleFist.equals('剪刀') && comFist.equals('石頭') || peopleFist.equals('布') && comFist.equals('剪刀')) { System.out.println(computer.getName() + '贏了'); computer.addScore(1);}count++; } if (people.getScore() > computer.getScore()) {System.out.println(people.getName() + '贏了 ' + 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() + '贏了 ' + computer.getScore() + ':' + people.getScore()); } System.out.println('是否開始新游戲：'); 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('請出拳：'); Scanner scanner = new Scanner(System.in); String fist = scanner.next(); return fist; }}

電腦

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 = '石頭'; }else if(n == 1){ fist = '剪刀'; }else { fist = '布'; } System.out.println('對方出的是：'+fist); return fist; }}
