Recursion has more expressive power than iterative looping constructs. I say this because a while loop is equivalent to a tail recursive function and recursive functions need not be tail recursive.

This is one of the most common examples of the need for recursive functions. Recursive functions, at their simplest, are functions that call themselves. These types of functions are used in the ...

This Java recursion tutorial shows you how to create a recursive Java factorial function and compares these methods to iterative ones.
