Book about writing optimized and performing code in Java [closed]

Question

Please can you suggest me a good book about writing performing and optimized code in Java? A book that moves from something of "basic" like e.g. "is more performing a static or local variable?" to something more complex.

If it exists of course :)

Thank you very much, Julio

Go for Effective Java - Joshua Bloch.

Copying some of the outstanding comments on this book,

1. If every Java developer read this book, there would be a lot less broken code in the world.

2. "I sure wish I had had this book ten years ago. Some might think that I don't need any Java books, but I need this one." -- James Gosling, Fellow and Vice President, Sun Microsystems, Inc.
