import java.awt.*;
import javax.swing.*;
import java.awt.event.*;

public class clientPane extends JFrame implements ActionListener
{    private Container container;
    private JLabel label1,label2;
    private JTextField field1,field2;
    private JButton button1,button2,button3;
    private JPanel panel;
  public clientPane()
  {   setBounds(300,200,450,450);
  label1=new JLabel("客户姓名：");
  label2=new JLabel("密码");
  field1=new JTextField();
  field2=new JTextField();
  button1=new JButton(" 确定");
  button2=new JButton("取消");
  button3=new JButton("新用户注册");
  label1.setBounds(80,80,80,30);
  label2.setBounds(80,120,80,20);
  field1.setBounds(160,80,80,20);
  field2.setBounds(160,120,80,30);
  button1.setBounds(90,160,80,30);
  button2.setBounds(200,160,80,30);
  button3.setBounds(250,80,100,50);
  Container container=this.getContentPane();
  container.add(label1);
  container.add(label2);
  container.add(field1);
  container.add(field2);
  container.add(button1);
  container.add(button2);
  container.add(button3);
  button1.addActionListener(this);
  button2.addActionListener(this);
  button3.addActionListener(this);

  /*container.setLayout(new BorderLayout());
  panel=new JPanel();
  panel.setLayout(new GridLayout(3,2));
  panel.add(label1);
  panel.add(field1);
  panel.add(label2);
    panel.add(field2);
  panel.add(button1);
  panel.add(button2);
  container.add(panel,BorderLayout.CENTER);
  container.add(button3,BorderLayout.SOUTH);*/

  show();

    }


    public void Actionpeerformed(ActionEvent e)
    {
      }
    public static void main(String[] args)
{ clientPane application=new clientPane();
  application.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

  }



  }
为什么当我点里面的fields或者buttons时里面的安纽看不见了
并且界面发生了很多的变化
为什么？
