I'm working on a school project and I'm having trouble changing the background colour. For some reason it keeps showing up as the default grey colour instead of black.

//creates PoolTable claa
public class PoolTable extends JPanel implements Runnable, KeyListener, MouseListener, MouseMotionListener
{
//creates size of the play screen.
public JFrame myFrame = new JFrame("Pool!");
private JPanel panel = new JPanel();
private int gameWidth;
private int gameHeight;
public PoolTable()
{
int width = 750;
int height = 500;
myFrame.setTitle("Pool");
myFrame.getContentPane().setBackground(Color.BLACK);
myFrame.setSize(width, height);
myFrame.setResizable(false);
myFrame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
myFrame.setContentPane(this);
myFrame.setVisible(true);
}
}
You are replacing default content pane with yours one. so change background color after replacing content pane.
myFrame.setContentPane(this);
myFrame.getContentPane().setBackground(Color.BLACK);
OR do
this.setBackground(Color.BLACK);
