SCJP Tutorials
The Sun Certified Java Programmer (SCJP) tutorials in this section provide IT professional interested in getting certified as SCJP. The SCJP certification process is a prerequisite to other Java-related software certification processes and is a valuable skill that any computer sciences professional should attain. The SCJP exam is an entry-level test, designed to secure that a developer has a working knowledge of the Java programming language.
SCJP tutorials encompass the basics of the Java programming language that will be examined in the SCJP certification process such as declarations, initialization, scoping, flow control, API contents, collections and generics. All of these areas of the SCJP tutorials provide thorough details and explanations of each including sample code to assist the programmer in learning about the Java language.
SCJP certification process includes a multiple-choice exam consisting of 72 questions that a potential certification holder will have to complete in a 175-minute time restraint. Using the tutorials as a study guide, the programmer or developer will be given tips, tricks and valuable information geared toward enabling the IT professional to pass the SCJP examination. Sun Microsystems, Inc. has created a test that focuses on writing code and examining a developer’s performance under pressure, rather than testing a series of memorized details.
