Hey TechGuys out there i am trying learn java data structures, LinkedList class and i am simply not getting anything. Can anyone shed some light on how to solve this problem with explanation commented as each code goes thru..

There has to be a class named Student that includes String data fields for firstName and lastName.  There has to be a constructor that requires two String parameters to populate the firstName and lastName fields. There has to be a List of 20 Student objects each having different first and last names.  Finally Print  LinkedList, first in the order your items were placed onto the LinkedList and then in reverse order.  Required  files to be saved as Student.java and ClassRoster.java.
