Hovering over JButtons and displaying a message

Question

I want to hover over a number of JButtons on my GUI (map) and display the name of that location e.g. Manchester and London. I have the code working for one button, but it does not work for more than one button and prints the last out message (as i have 10 buttons) for all button locations.

If button1 is true it then draws the text on the GUI in the specified area via my paintComponent() method.

How can i resolve this?

button1.addMouseMotionListener(this);
button2.addMouseMotionListener(this);

public void mouseMoved(MouseEvent arg0)
{
    if(button1.contains(arg0.getPoint()))
    {
        button1  = true;
        out = "test 1";
        repaint();
    }

    if(!button1.contains(arg0.getPoint()))
    {
        b1 = false;
        out = " ";
        repaint();
    }//same for all 10 buttons but change variables
}

Why not use the tool tip API that already exists?

button.setTooltip("Manchester");

You even use HTML text to produce formatted results.

button.setTooltip("<html>Manchester<br>53.4800° N, 2.2400° W</html>");

If the images are embedded, you can even supply an image...

button.setTooltip("<html><img src=" + getClass().getResource("/someimage") + "/>Manchester<br>53.4800° N, 2.2400° W</html>");

*"If the images are embedded, you can even supply an image..."* They don't absolutely have to be embedded, though if so that is a) faster & b) usable by sand-boxed apps. – Andrew Thompson Feb 21 '13 at 02:10
@AndrewThompson Ah true, it could be any valid `URL` – MadProgrammer Feb 21 '13 at 02:27

don't to use MouseListener or MosueMotionListener from JButton, this method are correctly implemented in JButtons API,
there no reason, I can't found reason to use repaint() for this job
another way is add ChangeListener to JButton and take rellated event(s) from derived ButtonModel
for better help sooner post an SSCCE, short, runnable, compilable, just about JFrame with one JButton

Well this answer is coolio for JDK 8 users, so try it out:

for regular text

buttonyoumade.setToolTipText("Text you choose");

for html use

anotherbuttonyoumade.setToolTipText("<html> any valid html code </html>");
