If you re instructed to use Swing (and we can virtually guarantee you will be), you must understand the Listener paradigm. Be certain that you understand how Swing components are meant to handle events, and how components relate to their models and their listeners. In addition, you should understand how inner classes are used to help implement these capabilities.

design aspects that will be applicable across most of the GUI projects you encounter. Once again, we are approaching this topic with our infamous 80/20 perspective; this chapter provides the core information you need to design GUIs that are easy to learn, easy to use, and ergonomically friendly. There are eight steps to designing a great GUI:

The Sun developer s exam is by its nature an artificial exercise. We all understand that there are no real end users and no real business with real issues being addressed here. The rest of this section is written assuming that you re creating a solution for a real scenario. So, for the exam, you ll just have to pretend that you are the user, the business manager, etc. Even though you re a one-person band, you can follow this process at least for the exam.
Interviews, Observation, and Iteration
A GUI will always be better if it s designed with the help of the end-user community. No matter how many businesses you ve helped to automate, or how many killer GUIs you ve built in the past, end-user input is essential. Although there are many ways of interacting with the end user, the three ways that offer the best return are
Observing the end user performing the process that you hope to automate.
From now on we ll just call it the process.
Creating a Usable and Extensible GUI
Interviewing the end user about the process that he or she performs what
information is used, what decisions are made, what steps are taken, and what is created.
Reviewing your results, and refining your implementation, with the user, over
and over again at every stage of development.
Creating Use-Cases
A very effective approach to designing a GUI is to create use-cases with the user as you work through the observation and interview stages. Use-cases let you encapsulate the transactions that the end user performs over and over again in his or her job. Let s say that you re creating a system to help customer service representatives (CSRs) at a company that sells PCs over the phone. After talking with the CSRs and watching them work, you might discover that they perform the following tasks over and over again in the context of working with their clients:
Create a new customer record. Modify information in an existing customer record. Place a new order. Modify an existing order. Cancel an order.
Each of these activities can be considered a use-case. Once you ve generated a list of use-cases for your application, the next step is to flesh them out. We like to use 4 6 cards for this. Each use-case is listed on its own card, and then for each card we add the following headings:
Find
How do you find the information you need to perform the use-case What information is needed for the use-case to be completed
