Java JFrame background color not working

Question

I tried using:

frame1.getContentPane().setBackground(Color.yellow);

But it is not working. Can anyone help me?

import java.         


        

Answer 1

Just put your setVisible(true); at the end of your constructor.

Moreover you had added mainPnl on your JFrame, so changing colour of the JFrame will be useless,

so instead of writing

add(mainPnl);

in your GameFrame class, you better be using

setContentPane(mainPnl);

for frame1.getContentPane().setBackground(Color.YELLOW); to work.

Hope this might help
