More generally, attempting an operation on an ineligible element whose completion would not result in the insertion of an ineligible element into the set may throw an exception or it may succeed, at the option of the implementation. Such exceptions are marked as "optional" in the specification ...

List is an ordered collection and can contain duplicate elements. You can use it when you need to maintain the insertion order or when duplicates are important. Here’s how to use a List: List<String>list=newArrayList<>();list.add('Java');list.add('Java');System.out.println(list);//...
* operations and their variants. Insertion, removal, and access * operations safely execute concurrently by multiple threads. * Iterators are weakly consistent, returning elements * reflecting the state of the set at some point at or since the * creation ...

To avoid such issues, implementations of this interface are encouraged to not permit insertion of null elements. (Note that sorted sets of Comparable elements intrinsically do not permit null.) Methods subSet(E, E), headSet(E), and tailSet(E) are specified to return SortedSet to allow ...
