The Sun Java Technology Professional Program


How do you code an MVC pattern? What is refactoring? How do you meet all the requirements without changing the base code Sun provides? Which is worse ”an application that has been overengineered with too many patterns, and one that works but isn't reuseable because the developer never heard of patterns? The Java community has adopted patterns faster than other language communities have. Having Java leaders champion something as theoretically sound as patterns is a healthy trend.

One of the results of Java's popularity is the high demand for skilled Java programmers and developers. However, because of Java's brief existence, experienced Java programmers are hard to find. Few in the field have more than five years of experience in developing Java applications. This is a problem for both employers and programmers. Employers cannot rely on the traditional number of years of experience in selecting senior-level Java programmers and software engineers , and star Java programmers have a hard time differentiating themselves from entry-level Java programmers.

Sun's Java certifications help both employers and programmers figure out who knows their stuff and who just says they do. Employers can identify skilled Java programmers by their certification level. Programmers and software engineers can attest to their knowledge of Java by citing their certification credentials.

The Java certification program consists of four certification exams:

  • Programmer exam ” The Programmer exam tests the candidate's knowledge of the Java language and basic application programming interface (API) packages. The exam consists of 59 multiple-choice questions.

  • Developer exam ” The Developer exam tests the candidate's ability to complete an extended programming assignment and answer questions about issues and trade-offs involved in completing the assignment. Programmer certification is a prerequisite to Developer certification. This book prepares you for the Developer exam.

  • Web Component Developer exam ” The Web Component Developer exam tests the candidate's knowledge of developing Java Web applications using Java servlets and JavaServer Pages (JSP). The exam consists of 60 multiple-choice questions. Programmer certification is a prerequisite to Web Component Developer certification.

  • Architect exam ” The Architect exam tests a candidate's familiarity with the technologies used to build Java-based enterprise applications and the candidate's ability to resolve issues in Java application design. This exam focuses on much higher-level software- and system-engineering skills than the other exams. It consists of a 48-question multiple-choice exam, an architecture and design project, and a four-question essay exam.

The Java Community Process is the group that decides which features go into the next version of Java, but has nothing to do with the Java certification exam. This group holds the responsibility for developing Java technology. It is an open , inclusive organization of active members and nonmember public input.
