Graphics in Java Point (Graphics2D): o An abstract class- cannot be instantiated o Instead a very short line can be made Line Method (Graphics): o g.drawLine(x1, y1, x2, y2); Line Class (Graphics2D): o g.draw(new Line(x1, y1, x2, y2)); (x2, y2) (x1, y1)

Graphics in Java Rectangle Method (Graphics): o g.drawRect(posX, posY, width, height) Rectangle2D Class (Graphics2D): o g.draw(new Rectangle(posX, posY, width, height)) (posX, posY) width (posX, posY) height

Graphics in Java Oval Method (Graphics): o g.drawRect(posX, posY, width, height) Ellipse2D Class (Graphics2D): o g.draw(new Ellipse2D.Double(posX, posY, width, height)) (posX, posY) width (posX, posY) height
