The book is a good reference book to prepare for the Java/J2EE interview.
It covers lots of topics like Java/J2EE/Spring/Struts/XML/Design Pattern/Database and is a handy to keep a copy on tablet or laptop.
The language is simple and some of the topics like Strings, collections, design pattern is covered nicely.
The java example chapter is also good.
