本文实例讲述了java实现的简单猜数字游戏代码。分享给大家供大家参考。

具体代码如下：

复制代码 代码如下:

import java.util.inputmismatchexception;
import java.util.scanner;

public class main {
        public static void main(string[] args) {
                // 产生一个随机数
                int number = (int) (math.random() * 100) + 1;

                // 加入count
                int count = 0;

                // 在这里加入最大值，和最小值
                int max = 100;
                int min = 1;

                while (true) {
                        // 键盘录入数据
                        scanner sc = new scanner(system.in);
                        system.out.println("请输入你要猜的数据：(" + min + "~" + max + ")");
                        try {
                                count++;
                                int guessnumber = sc.nextint();
                                // 判断
                                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");
                                        // 问是否继续
                                        system.out.println("请问还要继续吗？(yes)");
                                        sc = new scanner(system.in);
                                        string str = sc.nextline();
                                        if ("yes".equals(str)) {
                                                // 重写赋值随机数
                                                number = (int) (math.random() * 100) + 1;
                                                count = 0;
                                                max = 100;
                                                min = 1;
                                        } else {
                                                break;
                                        }
                                }
                        } catch (inputmismatchexception e) {
                                system.out.println("你输入的数据有误");
                        }
                }
        }
}

运行结果如下图所示：

希望本文所述对大家的java程序设计有所帮助。
