Java , Removing object from ArrayList

Question

I have ClassA which has a static ArrayList of Objects

public static ArrayList meteorits = new ArrayList();

Answer 1

Basically, you need to use iterator to avoid such concurrent modification:

List list = new ArrayList<>();
for (Iterator iterator = list.iterator(); iterator.hasNext();) {
    String string = iterator.next();
    if (string.isEmpty()) {
        iterator.remove();
    }
}
