"Problem With GroupLayout", Please Help !

Hi,
i am having a problem with the code which i have written. It is not giving the desired output. i.e i wanted to place in first line a label and a text field and in second line also same a label and a text field. But i am getting all the four components in a line. Can any body give me the solution please. Here is my code.Please point where to modify it.

import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import static javax.swing.GroupLayout.Alignment.*;

public class exp5 extends JFrame
{
private Container c;
//private GroupLayout gl;

public exp5()
{
super("Experiment5");
c = getContentPane();
JPanel panel = new JPanel();
JLabel name = new JLabel("Name");
JLabel age = new JLabel("Age");
JTextField tf = new JTextField(20);
JTextField tf1 = new JTextField(10);
GroupLayout layout = new GroupLayout(panel);
layout.setAutoCreateGaps(true);
layout.setAutoCreateContainerGaps(true);
layout.setHorizontalGroup(layout.createSequentialG roup().addComponent(name).addComponent(tf)
.addGroup(layout.createParallelGroup().addComponen t(age).addComponent(tf1))
);
layout.setVerticalGroup(layout.createParallelGroup ()
.addGroup(layout.createParallelGroup().addComponen t(name).addComponent(tf).addComponent(age))
.addComponent(tf1));

getContentPane().add(panel);
setSize(600,600);
setVisible(true);

}
public static void main(String args[])
{
exp5 exp = new exp5();
exp.addWindowListener(
new WindowAdapter()
{
public void windowClosing(WindowEvent e)
{
System.exit(0);
}
});
}
}

You have to think about both horizontal as well as vertical alignments in the layout.

Code:

---

import javax.swing.*;
import static javax.swing.GroupLayout.Alignment.*;
/**

public class GroupLayoutTest extends JFrame{

    public GroupLayoutTest() {
        JLabel name = new JLabel("Name");
        JLabel age = new JLabel("Age");
        JTextField tf = new JTextField(20);
        JTextField tf1 = new JTextField(20);
       
        GroupLayout layout = new GroupLayout(getContentPane());
        getContentPane().setLayout(layout);
        layout.setAutoCreateGaps(true);
        layout.setAutoCreateContainerGaps(true);
       
        layout.setHorizontalGroup(layout.createSequentialGroup()
                .addGroup(layout.createParallelGroup(LEADING)
                    .addComponent(name)
                    .addComponent(age))
                .addGroup(layout.createParallelGroup(LEADING)
                    .addComponent(tf)
                    .addComponent(tf1))
                );
       
        layout.setVerticalGroup(layout.createSequentialGroup()
                .addGroup(layout.createParallelGroup(BASELINE)
                    .addComponent(name)
                    .addComponent(tf))
                .addGroup(layout.createParallelGroup(LEADING)
                    .addComponent(age)
                    .addComponent(tf1))
                );
   
        setTitle("GroupLayout");
        pack();
        setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);
    }

    public static void main(String[] args) {
        // TODO code application logic here
        java.awt.EventQueue.invokeLater(new Runnable() {
            public void run() {
                new GroupLayoutTest().setVisible(true);
            }
        });
    }
   

}
