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.
