Query: Bad Coding in Examples

It seems to me that the two authors do not have much experience with good coding practices. The examples presented in the book contain useless idioms such as 'new String("success")'. A book with the word "professional" in the title should try to promote a better style.Also, the way information is presented in the book does not work for me. For instance when talking the authors are building examples after examples and then tell the reader that in practice this approach is unlikely to work. What is wrong with just getting to the point and telling people how to do it right. I have to confess I fell asleep repeatedly while trying to get to the point in the book where the authors may explain how to use tiles appropriately in large projects.
