import javax.swing.JFrame;
import javax.swing.JPanel;

public class Main extends JPanel {

  public void paint(Graphics g) {
    Graphics2D g2 = (Graphics2D) g;

    Ellipse2D e1 = new Ellipse2D.Double (20.0, 20.0, 80.0, 70.0);
    Ellipse2D e2 = new Ellipse2D.Double (20.0, 70.0, 40.0, 40.0);

    Area a1 = new Area (e1);
    Area a2 = new Area (e2);

    a1.intersects (new Rectangle(20,20,300,300));

    g2.setColor (;
    g2.fill (a1);

    g2.setColor (;
    g2.drawString ("intersect", 20, 140);

  public static void main(String[] args) {
    JFrame frame = new JFrame();
    frame.getContentPane().add(new Main());
