1. 1 Simple Phone Applet Lab 10

2. 2 Mobile Phone Display Area Send, Menu and End Numbers 0-9 * and #

3. 3 Layout of Mobile Phone Display Area Send, Menu and End Numbers 0-9 * and #

4. 4 You can type in the display area

5. 5 You can press numbers

6. 6 Panel 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.
