Why am I not getting a java.util.ConcurrentModificationException in this example?

Question

Note: I am aware of the Iterator#remove() method.

In the following code sample, I don\'t understand why the List.remove in main

Answer 1

Change Iterator for each into for loop to solve.

And the Reason is:

The iterators returned by this class's iterator and listIterator methods are fail-fast: if the list is structurally modified at any time after the iterator is created, in any way except through the iterator's own remove or add methods, the iterator will throw a ConcurrentModificationException.
