class - What is the most efficient way to construct a Java hash table related to filespecs -


i'm wondering efficient way make hash containing elements (in java).

i want have in hash objects of class node similar representing class file, don't use of functions , fields (i use path, filename , isdirectory), , implement few fields , methods specific objects.

important thing add constructors of nodes build basing on file objects. efficient - make node extend file or leave - unrelated moment of construction?

is node file? rare implement base class when aren't specific type of base.

it sounds don't need hierarchy in case, doesn't buy when storing metadata.
