Summary

This latest EDITION of Java for Students has been fully updated to include the new features of Java 5.0. The AUTHORs' GUI-based approach helps students to build their programming skills by producing exciting and dynamic graphical output. Hallmark features include: Oslash; A focus on applications and GUI development with Swing. Oslash; Graphics are used throughout to illustrate programming principles. Oslash; UML 2.0 is used for modelling and design. Oslash; A wealth of exercises and self-test questions with solutions. Oslash; A CD-ROM containing the JDK 1.5 and source code for all programs. Check out the companion website for the book at www.pearsoned.co.uk/bell to find additional resources for both students and instructors. About the AUTHORs Douglas Bell and Mike Parr have based the book on courses they teach at Sheffield Hallam University. They have also AUTHORed student texts on C# and VB .NET, and Douglas Bell is also the AUTHOR of Software Engineering for Students, now in its fourth EDITION.
