    The message displayed when the user hovers over a JButton is called a tooltip.

    You can create one using the code found in the Java tutorial here:
    http://docs.oracle.com/javase/tutorial/uiswing/components/tooltip.html

    To customize the background of the tooltip, you can do one of two things:

    • Change the Look and Feel

    • Use the following code to change the tooltip alone:

      UIManager.put("ToolTip.background", new ColorUIResource(255, 247, 200)); //#fff7c8
Border border = BorderFactory.createLineBorder(new Color(76,79,83));    //#4c4f53
UIManager.put("ToolTip.border", border);
ToolTipManager.sharedInstance().setDismissDelay(15000); // 15 second delay  
setToolTipText(message); // Message to display
