PanelPanel
to make Applet or Frame layout easier, we break a frame up into regions and compose each of them separately. Each region is called a Panel. Each can have its own different LayoutManager. Panels don't have any visible bounding lines. We can delimit them with differing background colours. If we want something to draw on with drawString and drawLine normally you would use a Canvas.
