Java的带GUI界面猜数字游戏的实现示例

作者:45552989

这篇文章主要介绍了Java的带GUI界面猜数字游戏的实现示例,文中通过示例代码介绍的非常详细,对大家的学习或者工作具有一定的参考学习价值,需要的朋友们下面随着小编来一起学习学习吧

先导包

import java.util.*;
import javax.swing.*;


再写主方法

public static void main(String[] args) {
}


新声明一个Scanner和随机数

public static void main(String[] args) {
	Scanner in = new Scanner(System.in);
	Random r = new Random();
}


让UIManager爬取系统窗口样式

try {
  UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());
} catch (Exception e) {
  e.printStackTrace();
}


新建一个int类型的变量存储随机数

int secret = r.nextInt(32) + 1;

写入主程序

JOptionPane.showMessageDialog(null, "电脑随机生成了一个1~32之间的数,请猜出这个数", "猜数字游戏", JOptionPane.PLAIN_MESSAGE);
String number2 = (String) JOptionPane.showInputDialog(null, "请输入想猜的数:", "猜数字游戏", JOptionPane.PLAIN_MESSAGE, null, null, "");
int number = Integer.parseInt(number2);
while (number != secret) {
  if (number > secret) {
    JOptionPane.showMessageDialog(null, "你猜的数大了,请继续猜", "猜数字游戏", JOptionPane.PLAIN_MESSAGE);
    number2 = (String) JOptionPane.showInputDialog(null, "请输入想猜的数:", "猜数字游戏", JOptionPane.PLAIN_MESSAGE, null, null, "");
    number = Integer.parseInt(number2);
  } else {
    JOptionPane.showMessageDialog(null, "你猜的数小了,请继续猜", "猜数字游戏", JOptionPane.PLAIN_MESSAGE);
    number2 = (String) JOptionPane.showInputDialog(null, "请输入想猜的数:", "猜数字游戏", JOptionPane.PLAIN_MESSAGE, null, null, "");
    number = Integer.parseInt(number2);
  }
}
JOptionPane.showMessageDialog(null, "恭喜你,你猜对了,电脑生成的随机数是" + secret, "猜数字游戏", JOptionPane.PLAIN_MESSAGE);


全部代码

package com.demo05;

import java.util.*;
import javax.swing.*;

public class MathDemo03 {
  public static void main(String[] args) {
    Scanner in = new Scanner(System.in);
    Random r = new Random();
    int secret = r.nextInt(32) + 1;
    try {
      UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());
    } catch (Exception e) {
      e.printStackTrace();
    }
    JOptionPane.showMessageDialog(null, "电脑随机生成了一个1~32之间的数,请猜出这个数", "猜数字游戏", JOptionPane.PLAIN_MESSAGE);
    String number2 = (String) JOptionPane.showInputDialog(null, "请输入想猜的数:", "猜数字游戏", JOptionPane.PLAIN_MESSAGE, null, null, "");
    int number = Integer.parseInt(number2);
    while (number != secret) {
      if (number > secret) {
        JOptionPane.showMessageDialog(null, "你猜的数大了,请继续猜", "猜数字游戏", JOptionPane.PLAIN_MESSAGE);
        number2 = (String) JOptionPane.showInputDialog(null, "请输入想猜的数:", "猜数字游戏", JOptionPane.PLAIN_MESSAGE, null, null, "");
        number = Integer.parseInt(number2);
      } else {
        JOptionPane.showMessageDialog(null, "你猜的数小了,请继续猜", "猜数字游戏", JOptionPane.PLAIN_MESSAGE);
        number2 = (String) JOptionPane.showInputDialog(null, "请输入想猜的数:", "猜数字游戏", JOptionPane.PLAIN_MESSAGE, null, null, "");
        number = Integer.parseInt(number2);
      }
    }
    JOptionPane.showMessageDialog(null, "恭喜你,你猜对了,电脑生成的随机数是" + secret, "猜数字游戏", JOptionPane.PLAIN_MESSAGE);
  }
}
