The CX310-066 (Sun Certified Programmer for the Java Platform, Standard Edition 6 Upgrade Exam) checks your real ability as a programmer. In fact, it is totally scenario based rather than knowledge based. The prerequisite for the test is that you must have successfully completed the previous version of the Sun Certified Programmer for the Java 2 Platform exam. This test requires you to have a good understanding of the Java language and the capability to write code for well-defined design applications. For this purpose, along with studying books and taking various practice tests, you should also practice with Java. There will be less number of direct questions, and more questions of ‘find the output’ type. Drag-n-Drop questions will test your hold on your knowledge in writing code. A good number of questions will be based on new topics added to the language in J2SE 5 and J2SE 6 versions. These topics are as follows: generics, autoboxing/unboxing, covariant return, variable length arguments, static import, enums, Console class, NavigableSet, NavigableMap, and for-each loop. Although not many direct questions will be there in the test, practicing them will help clear your fundamentals. You should practice the following things with Java to be confident enough to score well in the test:
- Write code that declares, constructs, and initializes arrays of any base type using any of the permitted forms, both for declaration and for initialization.
- Write code using the if and switch statements.
