Hello There I did have the same problem and after many attempts I found that the problem is that you need a Graphics Object to be able to draw  paint setBackgroundColor    My code usually goes like this   import javax swing    import java awt      public class DrawGraphics extends JFrame       public DrawGraphics String title  throws HeadlessException         super title         InitialElements               private void InitialElements          setSize 300  250         setDefaultCloseOperation JFrame EXIT ON CLOSE         setVisible true            This one does not work          getContentPane   setBackground new Color 70  80  70                public void paint Graphics draw           Here you can perform any drawing like an oval          draw fillOval 40  40  60  50          getContentPane   setBackground new Color 70 80 70              The missing part on almost all other answers is where to place the code  Then now you know it goes in paint Graphics G
