Hi Arulk,
We like to think that the book goes further in depth with the Java 7 features than most blog posts etc. We always like to explain why language features are designed a particular way :-). That said, Polyglot probably makes up about 1/3 of the book, with Groovy, Scala and Clojure covered as well as blended into other chapters such as rapid web development and the TDD chapter.
