Data Structures class question, please help!

Part II TRUE or FALSE. If the statement is false, then correct it to make it true. In the following, assume that you are storing employee records which are ordered by last name of the employee. You want to use a data structure from the JAVA COLLECTIONS LIBRARY to store this records. A TreeMap data structure will store records in-order. A HashMap data structure will store records in-order. A HashSet data structure will store records in order. A TreeMap data structure should be able to retrieve a record faster than a HashMap data structure. A TreeSet data structure will not allow duplicate records
