What are the benefits of using an iterator in Java

Question

I was browsing over the following code example:

public class GenericTest {
  public static void main (String[] args) {
    ArrayList myList = ne         


        

Answer 1

Basically, foreach loop is a shortcut for the most common use of an iterator. This is, iterate through all elements. But there are some differences:

• You can iterate through an array using foreach loop directly
• You can remove objects using an iterator, but you can't do it with a foreach loop
• Sometimes is useful to pass an iterator to a function (specially recursive ones)
