jpanel background magic numbers

Question

I don't want to use magic numbers. I'm setting a color to a jpanel background, Is there a possible way to use a color instead of

panel.setBackground(new color (255,255,255));

Thanks

Color class has static fields for most common colors. You can also define your own colors as constants and use them throughout your code.

Color myColor = new Color(1,2,3);
panel.setBackground(Color.RED);
panel.setBackground(myColor);

Why would you do that instead of just writing `panel.setBackground(Color.RED)` ? – Dawood ibn Kareem Oct 11 '13 at 09:50
@DavidWallace if it is used in many places it is shorter to write. it is a matter of preference. – Juvanis Oct 11 '13 at 09:52
If you really feel that the number of characters you have to type is an issue, then just use a static import, and write `panel.setBackground(RED);`. There's no point in creating a brand new variable when one already exists. – Dawood ibn Kareem Oct 11 '13 at 09:54
@HashCoder if you have a new question, you should ask a new question, rather than slipping it in here. – Dawood ibn Kareem Oct 11 '13 at 10:02

You can use the static fields of the Color class.

Ex:- BLACK , WHITE

panel.setBackground(Color.BLACK);
