Java Set collection - override equals method

Question

Is there any way to override the the equals method used by a Set datatype? I wrote a custom equals method for a class called Fee

Answer 1

One solution would be to use a TreeSet with a Comparator.

From the documentation:

TreeSet instance performs all element comparisons using its compareTo (or compare) method, so two elements that are deemed equal by this method are, from the standpoint of the set, equal.

This approach would be much faster than using a LinkedList, but a bit slower than a HashSet (ln(n) vs n).

It's worth noting a one side effect of using TreeSet would be that your set is sorted.
