Я получаю ConcurrentModificationException с моим циклом for, и я не знаю, как решить эту проблему.
Это мой код:
for(Map.Entry<String,ControlFieldVO> entry:oldPresentationMap.entrySet()) {
if(!keyValue.contains(entry.getKey())) {
oldPresentationMap.remove(entry.getKey());
}
Получение исключения concurrentModification в первой строке, пожалуйста, помогите, а ниже приведена трассировка стека:
