Set interface is Collection Interface Sub-interface, Set cannot insert repeating element in interfaceSet frequently used subclasses of interfaces:HashSet is a Set a subclass of the interface. Features: The inside can not store repeated elements, and the use of a hash of the storage mode. So there is no order. Treeset is also
