Effective Java

Designed to help Java programmers make the most effective use of the Java programming language and its fundamental libraries, this updated edition includes more than 50 essays, each of which conveys one rule. Helping programmers sidestep common misconceptions and errors, each rule captures best practices that have been tested in the real world.

Joshua Bloch is chief Java architect at Google and a Jolt Award winner. He was previously a distinguished engineer at Sun Microsystems and a senior systems designer at Transarc. Bloch led the design and implementation of numerous Java platform features, including JDK 5.0 language enhancements and the award-winning Java Collections Framework. He coauthored Java™ Puzzlers (Addison-Wesley, 2005) and Java™ Concurrency in Practice (Addison-Wesley, 2006).
