Exception Handling ConcurrentModificationException while removing elements from ArrayList while iterating it

0 votes

I'm trying to remove some elements from an ArrayList while iterating it like this:

for (String str : myArrayList) {
    if (someCondition) {
        myArrayList.remove(str);
    }
}

I am getting a ConcurrentModificationException when trying to remove items from the list at the same time when iterating myArrayList. Is there some simple solution to solve this problem?

Iterator<String> iter = myArrayList.iterator();

while (iter.hasNext()) {
    String str = iter.next();

    if (someCondition)
        iter.remove();
}
