public voiddraw(java.awt.Graphics2D g, java.awt.Component c)
Draw the example

	// Create the shape we'll work with.  See convenience method below.
	Shape pentagon = createRegularPolygon(5, 75);

	// Set up basic drawing attributes
	g.setColor(;                          // Draw in black
	g.setStroke(new BasicStroke(1.0f));               // Use thin lines
	g.setFont(new Font("SansSerif", Font.PLAIN, 12)); // Basic small font

	g.translate(100, 100);                        // Move to position
	g.draw(pentagon);                             // Outline the shape
	g.drawString("The shape", -30, 90);           // Draw the caption

	g.translate(175, 0);                          // Move over
	g.fill(pentagon);                             // Fill the shape
	g.drawString("The filled shape", -50, 90);    // Another caption

	// Now use a Stroke object to create a "stroked shape" for our shape
	BasicStroke wideline = new BasicStroke(10.0f);
	Shape outline = wideline.createStrokedShape(pentagon);

	g.translate(175, 0);                          // Move over
	g.draw(outline);                              // Draw the stroked shape
	g.drawString("A Stroke creates",-50,90);      // Draw the caption
	g.drawString("a new shape", -35, 105);

	g.translate(175,0);                           // Move over
	g.fill(outline);                              // Fill the stroked shape
	g.drawString("Filling the new shape",-65,90); // Draw the caption
