Figure 8-18. Demonstration of the JComboBox component and the BorderFactory
Listing 8-7 was designed to show how to make a simple border without introducing too
many new features at once. To that end, we put empty labels around the border just to make it
stand out—normally you would not do this in practice. Instead, you might consider using a
compound border, as shown in Listing 8-8. This will produce an almost identical result to that
shown in Figure 8-18.
