java實現的簡單猜數字遊戲代碼_java

本文執行個體講述了java實現的簡單猜數字遊戲代碼。分享給大家供大家參考。

具體代碼如下：

複製代碼 代碼如下:

import java.util.InputMismatchException;
import java.util.Scanner;

public class Main {
        public static void main(String[] args) {
                // 產生一個隨機數
                int number = (int) (Math.random() * 100) + 1;

                // 加入count
                int count = 0;

                // 在這裡加入最大值，和最小值
                int max = 100;
                int min = 1;

                while (true) {
                        // 鍵盤錄入資料
                        Scanner sc = new Scanner(System.in);
                        System.out.println("請輸入你要猜的資料：(" + min + "~" + max + ")");
                        try {
                                count++;
                                int guessNumber = sc.nextInt();
                                // 判斷
                                if (guessNumber > number) {
                                        max = guessNumber;
                                        System.out.println("你猜大了");
                                } else if (guessNumber < number) {
                                        min = guessNumber;
                                        System.out.println("你猜小了");
                                } else {
                                        System.out.println("恭喜你,花了" + count + "次就猜中了");
                                        // 問是否繼續
                                        System.out.println("請問還要繼續嗎？(yes)");
                                        sc = new Scanner(System.in);
                                        String str = sc.nextLine();
                                        if ("yes".equals(str)) {
                                                // 重寫賦值隨機數
                                                number = (int) (Math.random() * 100) + 1;
                                                count = 0;
                                                max = 100;
                                                min = 1;
                                        } else {
                                                break;
                                        }
                                }
                        } catch (InputMismatchException e) {
                                System.out.println("你輸入的資料有誤");
                        }
                }
        }
}

運行結果如下圖所示：

希望本文所述對大家的java程式設計有所協助。
