Solution

  • If you want the shapes to size according to your JPanel, make use of the JPanel's getWidth() and getHeight() e.g.

    int x = (int)(getWidth() * 0.1);
int y = (int)(getHeight() * 0.1);
int width = (int)(getWidth() * 0.8);
int height = (int)(getheight() * 0.8):
g.fillRect(x, y, width, height);

    See a full running example here
