Label not showing up.

Alright guys... not sure what's goin on here, but obviously something is happening that I"m unaware of. You can ignore the ActionEvent method at the bottom... What I want to do is have the word "test" about the text field.

package FifthFrame;
 
 
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
 
class MyJFrame extends JFrame implements ActionListener{
 
    // private instance variables
    JButton button;
    int buttonCount;
    JTextField inputLine;
    JLabel label;
 
    public static void main (String [] args) {
 
	MyJFrame mine = new MyJFrame();
        mine.setVisible(true);
 
    }
 
    public MyJFrame () {
 
        setTitle ("This is a \"MyJFrame\" object (V5)");
        setSize (300, 500);
        setDefaultCloseOperation( EXIT_ON_CLOSE );
 
        // get the content pane and set properties
        Container contentPane = getContentPane();
        contentPane.setBackground (Color.blue);
        contentPane.setLayout(null); // so that we can use absolute positioning
 
        // construct a button, and set the number of click on it to 0
        button = new JButton("0");
        button.setBounds(110,230,80,40);
	button.addActionListener(this);
        contentPane.add(button);
        buttonCount = 0;
 
        // construct a text field
        inputLine = new JTextField();
        inputLine.setBounds(100,100,100,20);
        inputLine.addActionListener(this);
        contentPane.add(inputLine);
 
        label = new JLabel ("test", JLabel.CENTER);
        label.setForeground(Color.white);
        contentPane.add(label);
 
    }
 
    public void actionPerformed(ActionEvent event) {
	buttonCount++;
	button.setText(Integer.toString(buttonCount));
        inputLine.setText("");
 
    }
}

First, I strongly recommend against using a null layout. While layouts can be a bit intimidating at first, they are extremely important in GUI design (see A Visual Guide to Layout Managers (The Java™ Tutorials > Creating a GUI With JFC/Swing > Laying Out Components Within a Container)). Second, the bounds of the label is never set, and this is necessary to position the component.

Alright, most of the code was pre-written like that. I'm supposed to just add a label. I wasn't aware that the bounds were required to be set - thanks.
