Java的带的带GUI界面猜数字游戏的实现示例 界面猜数字游戏的实现示例 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);
