(Select a font) Write a program that can dynamically change the font of a message to be displayed on a panel. The message can be displayed in bold and italic at the same time, and/or it can be displayed in the center of the panel. You can select the font name or font size from combo boxes, as shown in Figure 17.23. The available font names can be obtained using getAvailableFontFamilyNames() in GraphicsEnvironment (see Section 12.8, The Font Class). The combo box for the font size is initialized with numbers from 1 to 100.
