fail-fastiterator provides remove, set, and add operations. Note that not all the iterators support all these methods. As exp.ListIterator supportsadd()method but the general iterator doesn't. Withfail-safeiterator element-changing operations on iterators themselves (remove, set, and add) are no...
there is no term as fail-safe given in many places as Java SE specifications does not use this term. I am using fail safe to segregate between Fail fast and Non fail-fast iterators.
The concepts of fail-fast and fail-safe iterators emerged as relatively recent additions in Java, initially introduced alongside Concurrent Collections such as ConcurrentHashMap and CopyOnWriteArrayList in Java 5.Java Collections offer support for two distinct types of iterators: Fail-Fast iterators and ...
in the code snippet above, the iteration loops five times, which means it does detect the newly added element to the collection . 4. conclusion in this tutorial, we’ve seen what fail-safe and fail-fast iterators mean and how these are implemented in java. the code backing this article i...

In this article ,I would try to explain FAIL-FAST and FAIL-SAFE behavior of iterators. Let us first try to understand what is Iterator? Iterator is an interface defined in java.util package,with following methods declared in it : booleanhasNext();Enext();voidremove(); ...
Fail fast vs fail safe Java iterators Java iteratorprovides us with interface to parse the items of the underlying collection. When we are using the iterator the underlying collection should not be modified. If this treaty is not honoured and it is possible in a multi-threaded environment, then...
