Alphabetical order is the Default Natural Sorting order for String objects.
Ascending order is the Default Natural Sorting order for Numbers.
Object first(): Returns first element.
Object last(): Returns last element.
SortedSet headSet(Object o): Returns SortedSet whose elements are lessthan specified object .
SortedSet tailSet(Object o): Returns SortedSet whose elements are greaterthan or = specified object .
SortedSet subSet(Object o1, Object o2): Returns SortedSet whose elements are greaterthan or = specified object1 and lessthan specified object 2.
