java-puzzlers-sampler
This sampler contains one puzzle each chapter of Java Puzzlers by Joshua
Bloch and Neal Gafter (Addison Wesley, 2005). The book is filled with brainteas-
ers 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.
