One Minute Bottom Line

If you have read the The Pragmatic Programmer: From Journeyman to Master, you would enjoy this book too. Is similar about the comfortable pleasure to read this book.


For me was really hard write this book review due the approach used, Question and Answer. Furthermore the author categorized each question within a single or multiple key area. Some of these most important keys are:

  • Language Fundamentals LF
  • Specification Fundamentals SF
  • Design Concepts DC
  • Design Patterns DP
  • Performance Considerations PC
  • Memory Considerations MC
  • Transaction Management TM
  • Concurrency Considerations CC
  • SCalibility SC
  • Exception Handling EH
  • Best Practices BP
  • Software Development Processes SP
  • SEcurity SE

Some answers are covered in many pages, some of them with complete and snippet source code. Even more, really valuables images for a better and complete understanding are available, based on flow process and UML class diagram. I like this approach about the images due its excellent complement to complete the idea. About the source code available, respective explanation of its behavior is included too.

Something interesting are some settings about performance and something that I could call is about tricks or tuning. These appear some times throughout the book.

For many sections the author share many URL and some tools for our consideration. I like this too

If you are an experimented Java Developer you could find this book valuable how reference and to be honest is wise always re fresh your own knowledge

Again, since this book is based on Question and Answer, I will show the TOC including the most important sections (for each section, it contain many questions with its respective answer). See the TOC for a complete reference

    • Interviewers place a lot of value in "I don't know" over inventing answers
    • Books can impart knowledge, but cannot give you the much needed experience

Practically in the index you can see each question available in its respective section

The book's title fits perfect about what it offer you

What I liked:

  • Valuable and a huge amount of source code!
  • A lot of theory and explanation available
  • You can read the entire book comfortably
  • A good amount of UML class diagram and many images to represent some flow process

What I disliked:

  • None

You have covered lot of in your books. It looks like its a very helpful book for a person starting its career in Java.

You did not cover the J2EE topics in this book. Like a Java Programmer without J2EE expertise in nothing.
