What s New in the Second Edition

What's New in the Second Edition

As stated often in this introduction, my vision for the first edition was primarily a conceptual book. Although I still adhere to this goal for the second edition, I have included several application topics that fit well with object-oriented concepts. These applications include the following:

• Object modeling

• Object persistence

• XML

• Objects and the Internet

• The enterprise

• Design patterns

The chapters that cover these topics are still conceptual in nature; however, several of the chapters include Java code that shows how these concepts are implemented.
