I encourage you to email me with any questions you may have involving interfaces, or any other topic covered in this article or previous Java 101 articles. (Please, keep such questions relevant to material discussed in this column's articles.) In future articles, I plan to introduce a question-and-answer section, where I publish your questions along with my answers.

Next month's article will conclude this series by focusing on polymorphism and abstract classes. Also, that article presents the second Java 101 quiz. You might want to start studying!
