猜数字游戏java，要用到GUI图形界面，且运行要有次数限制

测试效果如图

参考java代码和注释如下

import javax.swing.*;

import javax.swing.border.*;

import java.awt.*;

import java.awt.event.*;

frame.setVisible(true);// 窗口可见

} catch (Exception e) {

}

});

}

public GuessNumFrame() {

setTitle("猜数字");

setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
