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

for (String str : myArrayList) {

    if (someCondition) {




Of course, I get 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?

Try an Iterator and call remove():

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

while (iter.hasNext()) {

   String str =;

   if (someCondition)
