About the Author
Khalid A. Mughal is an Associate Professor at the Department of Informatics at the University of Bergen, Norway. Professor Mughal is responsible for designing and implementing various courses, which use Java, at the Department of Informatics. Over the years, he has taught Programming Languages (Java, C/C++, Pascal), Software Engineering (Object-Oriented System Development), Data bases (Data Modeling and Database Management Systems), and Compiler Techniques. He has also given numerous courses and seminars at various levels in object-oriented programming and system development, using Java and Javarelated technology, both at the University and for the IT industry. He is the principal author of the book, responsible for writing the material covering the Java topics.
Professor Mughal is also the principal author of an introductory Norwegian textbook on programming in Java (
Java som første programmeringsspråk/Java as First Programming Language, Third Edition, Cappelen Akademisk Forlag, ISBN-10: 82-02-24554-0, 2006), which he co-authored with Torill Hamre and Rolf W. Rasmussen. Together they have also published another textbook for a 2-semester course in programming (
Java Actually: A Comprehensive Primer in Programming, Cengage Learning, ISBN-10: 1844809331, 2008).
His current work involves applying Object Technology in the development of content management systems for publication on the Web, and security issues related to web applications. For the past seven years he has been responsible for developing and running web-based programming courses in Java, which are offered to offcampus students.
He is also a member of the Association for Computing Machinery (ACM).
Rolf W. Rasmussen is the System Development Manager at vizrt, a company that develops solutions for the TV broadcast industry, including real-time 3D graphic renderers, and content and control systems.
Rasmussen works mainly on control and automation systems, video processing, typography, and real-time visualization. He has worked on clean room implementations of the Java class libraries in the past, and is a contributor to the Free Software Foundation.
Over the years, Rasmussen has worked both academically and professionally with numerous programming languages, including Java. He is primarily responsible for developing the review questions and answers, the programming exercises and their solutions, the mock exam, and all the practical aspects related to taking the SCJP exam presented in this book.
As mentioned above, he is also a co-author of two introductory textbooks on programming in Java.

ForewordForeword
Consider the following observations:
- Software continues to become ever more pervasive, ever more ubiquitous in our lives.
- Incompetence seems to be the only thing we can count on in today’s world and, especially, in the domain of software.
- The Java programming language has become a lingua franca for programmers all over the world.
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 brings us to this book.
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 plethora of books have been written purporting to tutor programmers in the programming language and platform skills they require.
The choice is as mind boggling as the material within the books themselves. Should one try Java for Frontally Lobotomized Simians or Postmodern Java Dialectics? The readership for these books is largely self selecting. I trust that if you, the reader, have gotten this far, you are looking for something that is intelligent, yet practical. This book is one of the finest efforts in this crowded arena. It brings a necessary level of academic rigor to an area much in need of it, while retaining an essentially pragmatic flavor.
The material in this book is probably all you need to pass the Java certification exam. It certainly isn’t all you need to be a good software engineer. You must continue learning about new technologies. The hardest part of this is dealing with things that are completely different from what you are familiar with. Yet this is what distinguishes the top flight engineer from the mediocre one. Keep an open mind; it pays.
