Drawing Basic Shapes

There are two ways to draw basic shapes like lines and rectangles. The first is to use specific drawing methods like Graphics.drawOval(). This example uses these methods. The second is to construct a shape and then use Graphics2D.draw() to draw the shape. See the java.awt.geom package for examples that create shapes.

 g2d.drawLine(x1, y1, x2, y2);
 g2d.drawArc(x, y, w, h, startAngle, arcAngle);
 g2d.drawOval(x, y, w, h);
 g2d.drawRect(x, y, w, h);
 g2d.drawRoundRect(x, y, w, h, arcWidth, arcHeight);
     
 Polygon polygon = new Polygon();
 polygon.addPoint(x, y);
 // ...continue adding points
 g2d.drawPolygon(polygon);
