But can you actually build something in it? Youll hear that argument from some whove never taken (or passed) the programmers exam. Obviously, they dont understand how darn difficult the programmers exam actually is, but nonetheless there is something to the claim that, just because you know how the compiler and VM work does not mean you can develope software. The Developer exam, which is unique in the IT exam world, lets you answer that question (most often posed by a prospective employer). In the Developer exam, you get to put your code where your mouth is by developing a software application. In fact, the Developer exam isnt even a multiple-choice test but rather a project that you build, given a (somewhat sketchy) specification. Youre told what to build, with some general guidelines, and then its up to you to implement and deliver the program. You have an unlimited amount of time in which to finish the project (as of this writing), but there is a short follow-up essay exam (taken at an authorized testing center, just as the Programmer exam is). The follow-up questions are largely used to verify that it was you (not your hotshot programmer brother-in-law who owed you big time) who did the work. In other words, the follow-up exam asks essay questions that only the project developer could answer (for example, Justify your design choice on). First, well lay out the facts of the examhow it works, how you do it, etc., and then well dive into what you need to know to pass it. Keep in mind that the actual knowledge you need to pass cannot be stuffed into a book this size, even if we made the book big enough to crush a car. Being a programmer is one thing, but being a developer is quite another. And you cant become a developer just by memorizing some facts. Study and memorization can work for passing the Programmers exam but thats OK because the programmers exam is designed to verify that youre smart and that you really know the language. A prospective employer doesnt have to train you in Java if youve passed the programmers exam. But if your employer wants to verify that you can follow a spec and implement a well-designed, maintainable, correct application, then you need either previous experience successfully building one or more Java applications or you need to pass the SCJD. The next seven chapters (in other words, the rest of the book) show you what...
