Consider the following observations:
One can draw varied conclusions from these comments. One of them is that it is of great importance that programmers working with the Java programming language should be as competent as possible.
The Java certification program is an important effort aimed at precisely this goal. Practitioners looking to obtain such certification need good quality training materials, which
Programming is still more of an art than a science, and will continue to be so for the foreseeable future. Mastering the intricacies of a large and complex programming language is a challenging task that requires time and effort, and above all experience.
Real programming requires more than just mastery of a programming language. It requires mastery of a computing platform, with a rich set of libraries. These libraries are designed to simplify the task of building realistic applications, and they do. Again, the practitioner is faced with a daunting task.
To address the clear need for professional training material, a
The choice is as mind boggling as the material within the books
The material in this book is probably all you need to pass the Java certification exam. It

The exam for the Sun Certified Programmer for Java 2 (SCPJ2) Platform has changed considerably since the first edition of this book was published. The most noticeable change in the current version of the exam (SCPJ2 1.4) is the removal of GUI and I/O, and the shifting of emphasis toward the
The I/O and GUI topics of the first edition have been eliminated, as they have no relevance for the SCPJ2 exam. These topics are more relevant for the Sun Certified Developer for Java 2 (SCDJ2) Platform exam and, therefore, relegated to a possible future volume on the Developer exam topics.
Since the emphasis of the SCPJ2 exam is on the core features of Java, the second edition provides an even greater
The second edition is still a one-source guide for the SCPJ2 exam: it provides a mixture of theory and practice for the exam. Use the book to learn Java, pass the SCPJ2 exam, and afterwards, use it as a handy language guide. The book also has an appendix devoted to the SCPJ2 Upgrade exam. To facilitate preparation for the exams, the second edition comes with a CD containing additional resources, including several mock exams developed by Whizlabs Software.
We have taken into consideration the feedback we have received from readers. The many hours spent in handling the deluge of e-mail have not been in vain. Every single e-mail is appreciated and is hereby
Preparing the second edition dispelled all our illusions about second editions being, to put it colloquially, a piece of cake. Every
