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 try Sets.symmetricDifference() from Eclipse Collections.

Set set1 = new TreeSet<>(Arrays.asList(501,502,503,504));
Set set2 = new TreeSet<>(Arrays.asList(502,503,504,505));
Set symmetricDifference =
        Sets.symmetricDifference(set1, set2);

Assert.assertEquals(
        new TreeSet<>(Arrays.asList(501, 505)),
        symmetricDifference);
