1. when you need to cause a component to redraw is the call to paint(g) invalid, why ? 2. When you override update, are we responsible for clearing the background of the component, why?
1. No, you can call the paint() method but it is not recommended because in larger programmes which can have several components calling paint() in very short time will cause cpu to be overloaded and system will work very slowly. 2.If you don't override update() then because of its default behaviour it will clear the component to its background color and then call paint().If you override it then its default behaviour is no more there and it will noy clear the background.
