public Iterator iterator()
public ListIterator listIterator()
public ListIterator listIterator(int index)

Using an iterator from a List is like using any other iterator. The order of the elements in the list is preserved.

import java.util.Arrays;
import java.util.Iterator;
import java.util.List;

public class MainClass {
  public static void main(String[] a) {

    List list = Arrays.asList(new String[] { "A", "B", "C", "D" });
    Iterator iter = list.iterator();

    while (iter.hasNext()) {
      System.out.println(iter.next());
    }

  }
}
