genetic copies to the rest of the world to evangelize Java.

I live in Asia, so you can probably guess that your book has made an impression

here. I learned basic Java and OO programming earlier this year and we had

a good course instructor.However, your book managed to crystallize some powerful concepts which I wanted to know but was too 'dumb' to ask in class.

I like the way you explain the use of Interface and use of pictures to explain

multi-inheritance and how Interface works. I like the chapter on serialization

and file I/O too. I have just finished an intermediate Java course and I wish my instructor had a picture showing the transition from 100% local apps to 100% remote apps as shown in your book. I like your Top Ten Reference section. Although, I know 'Strings are Immutable' but I have gained new insight after reading your comments on its impact on memory usage.

Please continue to produce more Head First Java books.
