Summary
In this chapter, we showed you how to use
iterators. Iteration is one of the most important concepts in
Web programming. As you progress through the remaining
chapters in this book, you will use iterations to process
other types of data, such as the results from an SQL
database.
This chapter also showed that you can use
iterators to perform basic string processing. In the next
chapter, you will learn how to properly format data for
display using JSTL's formatting tag library.
