In today's tight job market, certification is an important means for IT professionals to demonstrate their proficiency in a particular skill set. Certification is particularly key in the Java community, where five official exams are maintained by Sun, the creator of the Java language. Developers seeking to obtain such credentials regarding the J2SE component of Java are required to take the Sun Certified Java Developer Exam. This second edition is an indispensable guide for conquering the exam. Updated for the new Java version, J2SE 5.0, this book provides practical instruction for mastering these new features by working through a project with requirements and structure similar to the project found in the Sun Certified Java Developer (SCJD) examination.
