    panel = new MyPanel();
    getContentPane().add( panel, "Center" );

 public static void main( String [] args ){
    TestLine tl = new TestLine();
    tl.setVisible( true );

class MyPanel extends JPanel {
    final static BasicStroke stroke = new BasicStroke(2.0f);
    final static BasicStroke wideStroke = new BasicStroke(8.0f);

    public MyPanel(){}

    public void paintComponent( Graphics g ){
        Graphics2D g2 = (Graphics2D)g;
        g2.setStroke( stroke );
        g2.draw(new Line2D.Double(10.0, 10.0, 100.0, 10.0));
        g2.setStroke( wideStroke );
        g2.draw(new Line2D.Double(10.0, 50.0, 100.0, 50.0));
