一个视窗设计的很菜的问题。

小弟开始学JAVA的视窗设计，遇到一个问题，由于现实在没人可问，所以只能上来请大家指导指导。问题是，共有两个JPanel,运行一个jPanel1后，按下一个按钮后如何弹出另个一个JPanel呢,以下是程序的全部代码，事件部分是空的(注释的的那两行)，请高手帮忙填一下，不尽感激。(情况就类似于，运行一个程序，在程序界面上有一个按钮，叫“配置程序的参数”，按下去后弹出一个面板，可以进行参数的配置，完了按确定返回。)
package test;
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
class test extends JFrame{
JPanel jPanel1 = new JPanel();
JPanel jPanel2 = new JPanel();
JLabel jLabel1 = new JLabel();
JLabel jLabel2 = new JLabel();
JButton jButton1 = new JButton();
JButton jButton2 = new JButton();
BorderLayout borderLayout1 = new BorderLayout();
BorderLayout borderLayout2 = new BorderLayout();

public test() {
try {
jbInit();
}
catch(Exception e) {
e.printStackTrace();
}
}
private void jbInit() throws Exception {
jPanel1=(JPanel)this.getContentPane();
jLabel1.setText("this is panel1");
jLabel2.setText("this is panel2 ");
jButton1.setText("确定并返回panel1");
jPanel2.setLayout(borderLayout2);
jPanel1.setLayout(borderLayout1);
jButton2.setToolTipText("");
jButton2.setText("运行panel2设置程序运行参数");
jButton2.addActionListener(new test_jButton2_actionAdapter(this));
jPanel2.add(jLabel2, BorderLayout.SOUTH);
jPanel2.add(jButton1, BorderLayout.SOUTH);
jPanel1.add(jButton2, BorderLayout.SOUTH);
jPanel1.add(jLabel1, BorderLayout.NORTH);
jButton1.addActionListener(new test_jButton1_actionAdapter(this));
}
public static void main(String []args){
test t1=new test();
t1.setSize(new Dimension (300,400));
t1.setVisible(true);

}

void jButton2_actionPerformed(ActionEvent e) {
//运行panel2，进行系统参数的设置，并且panel1不可操作(就是鼠标点不到panel1了)，只能由panel返回后才能继续操作
/*下面是我自己以为的代码，是错误的
jPanel2=(JPanel)this.getContentPane();
jPanel2.setSize(new Dimension (300, 400));
jPanel2.setVisible(true);*/

}

void jButton1_actionPerformed(ActionEvent e) {
//设置完毕，返回panel1
}
}

class test_jButton2_actionAdapter implements java.awt.event.ActionListener {
test adaptee;

test_jButton2_actionAdapter(test adaptee) {
this.adaptee = adaptee;
}
public void actionPerformed(ActionEvent e) {
adaptee.jButton2_actionPerformed(e);
}
}

class test_jButton1_actionAdapter implements java.awt.event.ActionListener {
test adaptee;

test_jButton1_actionAdapter(test adaptee) {
this.adaptee = adaptee;
}
public void actionPerformed(ActionEvent e) {
adaptee.jButton1_actionPerformed(e);
}
}
