Centering a JLabel in an application

Question

Excuse me for being a noob, but it is really annoying me:
I just started with Java and wanted to create something simple and i though; what could be more simple than a program which displays your current IP and hostname. I got everything working exept the fact that i'm having trouble centering the JLabels containing the results on the screen. I was hoping someone could help me with this.
Many thanks in advance

import javax.swing.*;
public class Test {
    public static void main(String[] args) {
        JLabel label = new JLabel("text", SwingConstants.CENTER);
        final JFrame f = new JFrame("Test");
        f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        f.getContentPane().add(label);
        f.setSize(400, 50);
        SwingUtilities.invokeLater(new Runnable(){
            public void run() {
                f.setLocationRelativeTo(null);
                f.setVisible(true);
}There is a whole forum devoted to Swing, by the way...
