You
might override the equals() method so that it compares the unique VIN (Vehicle

Hashcodes are typically used to increase the performance of large collections of
data.

Collections such as HashMap and
HashSet use the hashcode value of an object to determine how the object should
be stored in the collection, and the hashcode is used again to help locate the object
in the collection.

if two objects are considered equal, their hashcodes must
also be equal

if you do need thread safety, there are utility methods in class Collections that can
help. Vector is the only class other than ArrayList to implement RandomAccess.

Keep in mind that a LinkedList may iterate more slowly than an ArrayList,
but it's a good choice when you need fast insertion and deletion.

With Java 5, primitives still have to be wrapped, but autoboxing
takes care of it for you.
