Collection is the root interface for all the hierarchy (except Map).
Set interface unique feature is that it does not accept duplicate elements. That is, no two elements will be the same.
SortedSet interface is derived from Set interface and adds one more feature that the elements are arranged in sorted order by default.
List interface permits duplicate elements.
Queue interface holds elements and returns in FIFO order.
Map adds the elements in key/value pairs. Duplicate keys are not allowed, but duplicate values are allowed. One key can map one value only.
SortedMap interface is a particular case of Map. Keys are sorted by default.
