| 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. |
