Description
The following code shows how to draw an Arc2D.Float.
Example
import java.awt.Color;
import java.awt.Graphics;
import java.awt.Graphics2D;
import java.awt.geom.Arc2D;
/*from w w w.j av a 2s . c o m*/
import javax.swing.JComponent;
import javax.swing.JFrame;
class MyCanvas extends JComponent {
public void paint(Graphics g) {
Graphics2D g2 = (Graphics2D) g;
// Draw the pie chart
Arc2D.Float arc = new Arc2D.Float(Arc2D.PIE);
arc.setFrame(140, 200, 67, 46);
arc.setAngleStart(45);
arc.setAngleExtent(270);
g2.setColor(Color.gray);
g2.draw(arc);
g2.setColor(Color.red);
g2.fill(arc);
g2.setColor(Color.black);
g2.drawString("Arc2D.PIE", 140, 190);
}
}
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.
