Introduction

The programs we have discussed thus far are generally structured as methods that call one another in a disciplined, hierarchical manner. For some problems, however, it is useful to have a method call itself. Such a method is known as a recursive method. A recursive method can be called either directly, or indirectly through another method. Recursion is an important topic discussed at length in upper-level computer science courses. In this chapter, we consider recursion conceptually, then present several programs containing recursive methods. Figure 15.1 summarizes the recursion examples and exercises in the book.
