How well do you really know Java? Are you a code sleuth? Have you ever spent days chasing a bug caused by a trap or pitfall in Java or its libraries? Do you like brainteasers? Then this is the book for you!
This book is filled with brainteasers about the Java programming language and its core libraries. Anyone with a working knowledge of Java can understand these puzzles, but many of them are tough enough to challenge even the most experienced programmer. Don't feel bad if you can't solve them. They are grouped loosely according to the features they use, but don't assume that the trick to a puzzle is related to its chapter heading; we reserve the right to mislead you.
