Set is the group of elements, or we can say collection of elements, that can never contains Duplicate element. If in case duplicate elements is added then Set Interface will not add it in that group of elements. Set also allow null element and as it avoids duplicity, so only one null i...
Here we have used no arguments to create a sorted set. Hence the set will be sorted naturally. Methods of SortedSet TheSortedSetinterface includes all the methods of the Set interface. It's becauseSetis a super interface ofSortedSet. Besides methods included in theSetinterface, theSortedSetin...
