This is an update of the only true "objects first" CS1 in Java book so that it is now fully compatible with the latest version of the language: Java 2 (a.k.a. JDK 1.2, and formerly referred to as Java 1.2). The book uses object-oriented concepts from the very beginning -- classes, objects, and messages are introduced in Chapter 1 -- and develops them throughout. The authors also provide an early introduction to testing, covering test drivers, debugging, and test case selection. Features All code is revised and tested to be compatible with Java 2 (and Java 1.1) Contains optional supplements covering graphical user interfaces (GUIs) at the end of each chapter Includes a chapter with three robust applications that use the text's class design procedure and allow students to tie the material together - from Amzon
