public class ShapeExample extends JPanel {

  private Rectangle2D.Double square =
    new Rectangle2D.Double(10, 10, 350, 350);

  public void paintComponent(Graphics g) {

    g2d.fill(circle);
    g2d.draw(square);
  }

  // super.paintComponent clears offscreen pixmap,
  // since we're using double buffering by default.

  protected void clear(Graphics g) {
    super.paintComponent(g);
  }

    return(circle);
  }

  public static void main(String[] args) {
    WindowUtilities.openInJFrame(new ShapeExample(), 100, 100);
  }
}

The error I am getting is this .

symbol  : variable WindowUtilities
location: class ShapeExample
    WindowUtilities.openInJFrame(new ShapeExample(), 100, 100);
    ^
1 error

What is wrong in the code?
