I have been out of touch with Java programming since 2008, want to catchup and see how far has it improved. Looking forward to read this new book hopefully will bring me to the latest and greatest in the Java/J2EE area.
J2SE 5.0 (Sept 30, 2004) brought in several additions to Java language. After this Java SE 7 (July 7, 2011) introduced many new additions. In between, there were no changes in the language syntax. If you have used Java till 2008, then you have not missed anything except for all the new additions (really major) in Java SE 7. Chapter 1 of the book summarizes changes made in each major release of Java. Reading the book would certainly help you in bringing you up-to-date with Java SE.
