Draw Ellipse and rotate 360 in Java

Description

The following code shows how to draw Ellipse and rotate 360.

Example


import java.awt.Graphics;
import java.awt.Graphics2D;
import java.awt.geom.AffineTransform;
import java.awt.geom.Ellipse2D;
/*  w  w  w .j a  v a2 s  .c  om*/
import javax.swing.JComponent;
import javax.swing.JFrame;

class MyCanvas extends JComponent {
  public void paint(Graphics g) {
    Graphics2D g2 = (Graphics2D) g;

    Ellipse2D e = new Ellipse2D.Double(0, 0, 80, 130);

    for (double i = 0; i < 360; i += 5) {
      AffineTransform at = AffineTransform.getTranslateInstance(400 / 2, 400 / 2);
      at.rotate(Math.toRadians(i));
      g2.draw(at.createTransformedShape(e));
    }
  }
}

public class Main {
  public static void main(String[] a) {
    JFrame window = new JFrame();
    window.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    window.setBounds(30, 30, 450, 450);
    window.getContentPane().add(new MyCanvas());
    window.setVisible(true);
  }
}

The code above generates the following result.
