problem with advance for loop

[vineet walia]

import java.util.*;
class class14 { 
     public static Iterator reverse(List list) {
	 Collections.reverse(list);
	 return list.iterator();
	 }
 
	public static void main(String[] args) {
		 List list = new ArrayList();
		 list.add(" 1"); list.add("2"); list.add("3");
		 for (Object obj: reverse(list))
		 System.out.print(obj + ",");
		 }
}

please explain whats wrong with this for loop
We can use for loop in case of array and instance of iterator
What I am not getting this code please explain this code please explain?

You should iterate over the list, not the iterator itself

  
public class IteratorTest
{
	public static void reverse(List list)
	{
		Collections.reverse(list);
	}

	public static void main(String[] args)
	{
		List list = new ArrayList();
		list.add(" 1");
		list.add("2");
		list.add("3");
		reverse(list);
		for (Object obj : list)
			System.out.print(obj + ",");
	}
}

  

[EDIT]

Removed extra whitespaces in code
