From source file:Main.java

public void paint(Graphics g) {
    Graphics2D g2 = (Graphics2D) g;
    int w = getSize().width;
    int h = getSize().height;

    Arc2D arc = new Arc2D.Double(0.0, 0.5, w, h, 0.0, 60.0, Arc2D.CHORD);

    g2.draw(arc);//  w  ww .  j  av a 2s  .  c  o  m

    arc.setArc(new Rectangle(2, 3, w, h), 80.0f, 110.0f, Arc2D.PIE);
