In this second example, we will take a nuts-and-bolts approach to exam preparation and code more examples of the major pieces. If you are unfamiliar with one or two of the major areas touched by the assignment------Swing development, say, or RMI implementation------these examples can help accelerate your own practice work. We will also take a closer look at the administrative and scoring details of the exam. To do this, we downloaded our own assignment and wrote a solution, so that we could match our discussion to the degree of difficulty we saw.
The Java 2 Developer?ˉs Exam, as exams of this type go, is not overly complex or subtle. The focus is competence in applying programming, design, and integration skills over a broad range of libraries and problem domains. The power of object-oriented design, of course, is that breaking a job into self-contained pieces is easy. The question lies in effective partitioning of the overall goal, but this is already answered by the assignment requirements. Some elements in the assignment code require fixing, but they are plainly disclosed in the exam notes------no hidden surprises. The top-level objectives are straightforward, and although there are one or two obstacles to extending the code that may appear novel to some candidates, they require less time in thinking than implementation to solve.
