Sams Teach Yourself Java in 24 Hours is a step-by-step tutorial broken up into 24 short, easy one-hour chapters. It starts out at a lower level than Sams Teach Yourself Java in 21 Days, and takes things at a slower pace, focusing on key programming concepts and essential Java basics. The basic structure of the book and many of its examples remain the same in this new edition, but the author makes use of dozens of reader comments to make improvements to explanatory text and example programs. Additionally, fresh material will cover new components of Java 2, including Java Foundation Classes, Java2D classes for two-dimensional image manipulation, and JavaBeans -- a feature of Java 1.1 that has become a key part of Java programming.

A very interesting book on the rudimentaries of Java. with sample codes to play with. ..but as a side note you may not be able to test all the codes and still be able to finish the book in 24 hours. funny and very interesting book.
