How do I set a JButton's fill color?

Question

How do I? Can I?

public class Jbutton {
    public static void main (String[] args){
    JButton button = new JButton("I'm colorful!");
    button.

What do I do here ^ to set the button color?

}
}

What the heck. Why do you keep asking questions that can be answered by simply looking things up? Why the lazy questions? Part of the skill set of being a decent programmer is learning how to find this information on your own, and you might wish to exercise this skill just a bit. — Hovercraft Full Of Eels, Dec 24 '14 at 00:43

You have 2 options either use setBackground or setIcon E.g.

button.setBackground(myColor);
button.setIcon(new javax.swing.ImageIcon(pathToIcon));

now how do I get it to turn red then turn back to the default color? – Caders117 Dec 23 '14 at 23:00
@CadeLikesToCode you can use javax.swing.Timer – sol4me Dec 23 '14 at 23:06
Just beware that using `setBackground` may not affect the "content area" of the button on some look and feels and could be ignored if the button is transparent... – MadProgrammer Dec 23 '14 at 23:09
@MadProgrammer Thats why Included 2 options – sol4me Dec 23 '14 at 23:10
What's the syntax for the timer @sol4me? – Caders117 Dec 23 '14 at 23:11
@sol4me I have no issue with your answer, it's just a FYI ;). If you didn't want the content area fill affect, you can actually turn it off ;) – MadProgrammer Dec 23 '14 at 23:11
@CadeLikesToCode That's beyond the scope of the original question, but take a look [How to use Swing Timers](http://docs.oracle.com/javase/tutorial/uiswing/misc/timer.html) for more details – MadProgrammer Dec 23 '14 at 23:12
@CadeLikesToCode better post a new question because its out of scope for this question – sol4me Dec 23 '14 at 23:13
@MadProgrammer Understand. Thanks :) – sol4me Dec 23 '14 at 23:19

Using your example:

public class Jbutton {
    public static void main (String[] args){
        //You're going to need some context for this like a JFrame
        JButton button = new JButton("I'm colorful!");
        button.setBackground(Color.RED);
    }
}

Though I think for a more enlightening section of code, you might explore This Question to see how some parts of swing and AWT work.

I believe its like so

{
JButton btn = new       
JButton(String.valueOf(i));
btn.setBackground(Color.BLACK);
btn.setForeground(Color.GRAY);
p3.add(btn);
}

Using my phone so trouble editing it to post code, that's what I used on a previous project though if that helps
