When double clicked on item, it also fires single click

Question

Hi,
I want to seperate a single click and a double click. I try doing this by using:
if (e.getClickCount() == 1)
fireSingleClick();
else if (e.getClickCount() >= 2)
fireDoubleClick();
But when I doublic click, it also fires the singleclick. Does anyone know how to prevent this?
thanks,
Hugo

Using the suggestions found on this page I came up with something that I think is a little easier to implement. First of all a few observations:
1) From my testing on Windows 98 it appears that the click count is incremented as long as the click is within about 500 milliseconds. To be consistent I set this as the default value for my class (not the 300 that appears to be used in most threads)
2) A double click will be processed immediately. On the other hand, a single click has to wait 500 milliseconds before being processed, just to make sure another click isn't received (which would make it a double click). Just seems a bit strange that a double clicks executes faster than a single click.
Here's the code:
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import javax.swing.event.*;
public class ClickListener extends MouseAdapter implements ActionListener
    MouseEvent lastEvent;
    Timer timer;
    long time;
    public ClickListener()
        this(500);
        time = System.currentTimeMillis();
    public ClickListener(int delay)
        timer = new Timer( delay, this);
    public void mouseClicked (MouseEvent e)
        if (e.getClickCount() > 2) return;
        lastEvent = e;
        if (timer.isRunning())
            timer.stop();
            doubleClick( lastEvent );
        else
            timer.restart();
    public void actionPerformed(ActionEvent e)
        timer.stop();
        singleClick( lastEvent );
    public void singleClick(MouseEvent e) {}
    public void doubleClick(MouseEvent e) {}
    public static void main(String[] args)
        JFrame frame = new JFrame( "Double Click Test" );
        frame.setDefaultCloseOperation( JFrame.EXIT_ON_CLOSE );
        frame.addMouseListener( new ClickListener()
            public void singleClick(MouseEvent e)
                System.out.println("single");
            public void doubleClick(MouseEvent e)
                System.out.println("double");
        frame.setSize(200, 200);
        frame.setVisible(true);
}
