public class Main {
  public static void main(String[] args) {
    JFrame jf = new JFrame("Demo");
    Container cp = jf.getContentPane();
    MyCanvas tl = new MyCanvas();
    cp.add(tl);
    jf.setSize(300, 200);
    jf.setVisible(true);
  }
}

class MyCanvas extends JComponent {

  public void paint(Graphics g) {
    Shape shape = new Rectangle2D.Float(100, 50, 80, 80);
    
    Graphics2D g2 = (Graphics2D) g;


    AffineTransform at = new AffineTransform();
    at.transform(new Point(1,2), new Point(2,3));
    
    
    g2.setTransform(at);
    g2.draw(shape);
    
  }
}
