Aug 5, 2013 · I need to draw a Polygon - by connecting consecutive points and then connecting the last point to the first. With this goal I tried to use drawPolygon(xPoints, yPoints, nPoints). To my mind it's ...

Discover how to effectively implement Polygon2D in Java 2D graphics with step-by-step guidance and clear code examples.

Mar 3, 2013 · JFrame does not have a paintComponent(Graphics g) method. Add the @Override annotation and you will get a compile time error. 1) Use JPanel and override paintComponent (you would than add JPanel to the JFrame viad JFrame#add(..))

public void paintComponent(Graphics g) { super.paintComponent(g); Polygon p = new Polygon(); for (int i = 0; i < 5; i++) p.addPoint((int) (100 + 50 * Math.cos(i * 2 * Math.PI / 5)), (int) (100 + 50 * Math.sin(i * 2 * Math.PI / 5))); g.drawPolygon(p); Polygon s = new Polygon(); for (int i = 0; i < 360; i++) { double t = i / 360.0;

This lesson shows you how to use the Graphics2D class to draw graphic primitives as well as arbitrary shapes, and how to display graphics with fancy outline and fill styles. These topics are discussed in the following sections.
