The top left of the drawing area is (0, 0), and we draw relative to this point. 2 The pixel coordinate system. drawLine(0, 0, 100, 100); 4 } Line 1 introduces the section of program which is executed when the button is clicked on. It is a method. Any instructions we place between the { of line 1 and the } of line 4 are executed in sequence, down the page.
