Java2D: Increase the line width

Question

I want to increase the Line2D width. I could not find any method to do that. Do I need to actually make a small rectangle for this purpose?

You should use setStroke to set a stroke of the Graphics2D object.

The example at http://www.java2s.com gives you some code examples.

The following code produces the image below:

import java.awt.*; import java.awt.geom.Line2D; import javax.swing.*;  public class FrameTest {     public static void main(String[] args) {         JFrame jf = new JFrame("Demo");         Container cp = jf.getContentPane();         cp.add(new JComponent() {             public void paintComponent(Graphics g) {                 Graphics2D g2 = (Graphics2D) g;                 g2.setStroke(new BasicStroke(10));                 g2.draw(new Line2D.Float(30, 20, 80, 90));             }         });         jf.setSize(300, 200);         jf.setVisible(true);     } } 

(Note that the setStroke method is not available in the Graphics object. You have to cast it to a Graphics2D object.)
