Best JAVA Book to LEARN!

"Head First Java", Head first is a series of books from O'Reilly Publishers, this book is supposed to be very user friendly, its quite different from all other serious programming language books we've used earlier, in my own opinion, this book is the "Best of the Best" for all Java Learners.
You can download the book Head First Java(2nd Edition) by Kathy Sierra and Bert Bates in pdf format from the link.
This is NOT a reference book. Head First Java is a book designed for learning, not an encyclopedia of Java Facts.
"HAPPY LEARNING"
