Symmetric difference of two sets in Java

Question

There are two TreeSets in my app:

set1 = {501,502,503,504}
set2 = {502,503,504,505}

I want to get the symmetric difference of thes

Answer 1

You could use CollectionUtils#disjunction

EDIT:

Alternatively with less pre-Java-5-ness, use Guava Sets#symmetricDifference
