Is ConcurrentHashMap Fail Safe?
concurrent package such as ConcurrentHashMap, CopyOnWriteArrayList, etc. are Fail-Safe in nature. In the code snippet above, we’re using Fail-Safe Iterator.

concurrent package such as ConcurrentHashMap, CopyOnWriteArrayList, etc. are Fail-Safe in nature. In the code snippet above, we’re using Fail-Safe Iterator. Hence, even though a new element is added to the Collection during the iteration, it doesn’t throw an exception.Click to see full answer. Also asked, what is fail safe and fail fast?Fail-safe iterators means they will not throw any exception even if the collection is modified while iterating over it. Whereas Fail-fast iterators throw an exception(ConcurrentModificationException) if the collection is modified while iterating over it.Additionally, is HashMap Fail Safe? Iterator on ArrayList, HashMap classes are some examples of fail-fast Iterator. This is because, they operate on the clone of the collection, not on the original collection and that’s why they are called fail-safe iterators. Iterator on CopyOnWriteArrayList, ConcurrentHashMap classes are examples of fail-safe Iterator. Simply so, is listIterator Fail Safe? 1. Using an Iterator: The iterators returned by ArrayList iterator() and listIterator() methods are fail fast: if the list is structurally modified at any time after the iterator is created, in any way except through the iterator’s own remove or add methods, the iterator will throw a ConcurrentModificationException.What is fail fast and fail safe in Java example? Fail Fast Vs Fail Safe Iterators In Java : Fail-Fast Iterators Fail-Safe Iterators Fail-Fast iterators doesn’t allow modifications of a collection while iterating over it. Fail-Safe iterators allow modifications of a collection while iterating over it.
