Currently I have an application which reads in a valid image and displays it on a JPanel. The user can then draw rectangles on this image within the JPanel. The problem I have is that I am unsure on how exactly the Paint() and Repaint() methods work in enabling for these user rectangles to be drawn? In essence I can define the parameters of a rectangle and call paint/repaint() but I have no either if I simply call JPanel.paint(Grahphics g) or JPanel.repaint().

The best way for you to understand is to study the code of an application that does what you want. There's an applet (makes no difference whether applet or application) called 'DrawTest' in the jdk demos.
