Concurrent Exception is the one which occurs while you try to do more than one operation on same property like it applies to collections in Java.

ex:

for (String s : set) {
set.add("String");
}

ConcurrentModificationException happens when you modify an object when you shouldn't. Most often, this happens when a collection is modified when you're iterating it.
