The CX310-055 (Sun Certified Programmer for the Java 2 Platform, Standard Edition 5.0) checks your real ability as a programmer. In fact it is totally scenario based, rather than knowledge based. 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 will be ‘find the output’ type. Besides, Drag-n-Drop questions have been added. A good number of questions will be based on new topics added to the language, i.e., on generics, autoboxing/unboxing, covariant return, variable length arguments, static import, enums and for-each loop. Although, not many direct questions will be there in the test, but practicing them will help clear your fundamentals. Practicing the following things with Java will make you 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 if and switch statements.
