Syntax

Graphics.fillPolygon(Polygon p) has the following syntax.

public void fillPolygon(Polygon p)

Example

In the following code shows how to use Graphics.fillPolygon(Polygon p) method.

import java.awt.Graphics;
import java.awt.Polygon;
//from w  w w.j  a v  a2  s.  c  o m
import javax.swing.JFrame;
import javax.swing.JPanel;

public class Main extends JPanel {

  public void paint(Graphics g) {
    super.paintComponent(g);
    int radius = 40;
    int centerX = 50;
    int centerY = 100;

    Polygon p = new Polygon();
    centerX = 150;
    for (int i = 0; i < 5; i++)
        p.addPoint((int) (centerX + radius * Math.cos(i * 2 * Math.PI / 5)),
                (int) (centerY + radius * Math.sin(i * 2 * Math.PI / 5)));

    g.fillPolygon(p);

  }

  public static void main(String[] args) {
    JFrame frame = new JFrame();
    frame.add(new Main());
    frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    frame.setBounds(20,20, 500,500);
    frame.setVisible(true);
  }
