Answer Posted / amol
The iterators for the concrete collection implementations
are fail-fast.
That means that if you are using an Iterator to traverse a
collection while underlying collection is being modified by
another thread, then the Iterator fails immediately by
throwing a ConcurrentModificationException (another
RuntimeException). That means the next time an Iterator
method is called, and the underlying collection has been
modified, the ConcurrentModificationException exception gets
thrown.
