Java實現的剪刀石頭布遊戲示例

本文實例講述了Java實現的剪刀石頭布遊戲。分享給大家供大家參考，具體如下：

ChoiceAnswer.java

 public class ChoiceAnswer { String texts[] = { "石頭", "剪刀", "布" }; int value; // 【1】石頭/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表示贏，返回-1表示輸*/ 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("歡迎使用・・・・・・"); p("請選擇：【1】石頭/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("你輸入的不正確！請重新輸入！"); 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,您和電腦均選擇了：" + userChoice.getText()); } else if (result == 1) { System.out.println("恭喜,您贏了！您選擇了：" + userChoice.getText() + "; 電腦選擇了：" + computerChoice.getText()); } else { System.out.println("對不起,您敗了！您選擇了：" + userChoice.getText() + ";電腦選擇了：" + computerChoice.getText()); } } void start() { showWelcome(); ChoiceAnswer userChoice = getUserChoice(); ChoiceAnswer computerChoice = getComputerChoice(); showResult(userChoice, computerChoice); } public static void main(String a[]) { System.out.println("武林網測試結果："); new Game().start(); }}
