你这是阿拉伯文？

直接粘过来就成这样了

package web;
import java.awt.Container;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;

import javax.swing.JButton;
import javax.swing.JDialog;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.SwingConstants;
class MyJDialog extends JDialog
{
    /**

    private static final long serialVersionUID = 1L;
    
    public MyJDialog(buttoncla frame)
    {
        super(frame,"第一个JDialog窗体",true);
        Container container=getContentPane();
        container.add(new JLabel("这是一个对话框"));
        setBounds(120,120,100,100);
    }
    
}
public class buttoncla extends JFrame {
    /**

    private static final long serialVersionUID = 1L;
    public static void main(String []args)
    {
        new buttoncla();
    }
    public buttoncla() {
        Container container=getContentPane();
        container.setLayout(null);
        JLabel jl=new JLabel("弹出对话框");
        jl.setHorizontalAlignment(SwingConstants.CENTER);
        container.add(jl);
        JButton bl=new JButton("弹出对话框");
        bl.setBounds(10,10,100,21);
        bl.addActionListener(new ActionListener() {
            public void actionPerformed(ActionEvent e) {
                new MyJDialog(buttoncla.this).setVisible(true);
            }
        });
        container.add(bl);
        setVisible(true);
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        setSize(200, 200);
    }
}

lack some settings as below:
setVisible(true);
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
setSize(200, 200);

rename the class name [buttoncla] by rules.
