Query: classic Java literature

This work has been intensively researched for many years, assuredly advancing the careers of those who chose to commit hours upon hours of their life learning about the Java language. This work covers topics other than JDBC, and this is one of the bright spots of the book because the context in which JDBC is important becomes apparent. For those who intend to eventually learn about persistence, hibernate, and other technologies, this is a very valuable work.
