Summary

Objects First with Java: A Practical Introduction Using BlueJ Third Edition David J. Barnes Michael Kouml;lling The BlueJ revolution goes on! The third edition of Objects First with Java has been fully updated for Java 5.0, and features a new version of BlueJ providing even stronger support for learning Java syntax and semantics. Hallmark features bull; bull;An 'Objects First' approach encourages students to exploit the power of OOP from the beginning bull;A project-driven approach applies a problem-solving method to real applications. bull;A CD-ROM containing the JDK and versions of BlueJ for a variety of operating systems bull;A Companion Website at www.pearsoned.co.uk/barnes includes a style guide for all program examples, PowerPoint slides and other resources for both students and instructors. bull;Additional resources can be found on the BlueJ website: www.bluej.org/objects-first/ New to the third edition bull; bull;Fully compliant with Java 5.0 features including generics bull;A revised treatment of autobox and enumerators bull;Expanded coverage of graphics and GUI programming bull;A new version of the BlueJ environment, featuring: o Full support for Java 5.0 o An all-new interface 'look and feel' o A new 'Code Pad' feature, allowing immediate execution and evaluation of Java code. About the Authors David Barnes has 25 years experience in teaching programming. He and Michael Kouml;lling both teach introductory Java courses at the Universityof Kent, Canterbury. Michael Kouml;lling was a key member of the team that developed BlueJ at MonashUniversityin Australia.

It is a pedagogical masterpiece."; -Ian Bridgewood, CopenhagenUniversityCollegeof Engineering
