Description
Assume a "Person" with 3 string properties age, name, hairColor. We've got
three people, Bob, Jane, and John - John happens to be bald, and his hairColor
property is "null". Trying to sort a collection of Person beans by hairColor
with a null entry throws a ClassCastException from ComparableComparator.
" java.lang.ClassCastException: There were nulls in the arguments for this
method: compare(hawkeye, null)' "
One should be able to sort a collection of beans on a property which contains
null values. The question that remains is whether the comparing with a null
should return a 1 or a -1 (do you want your nulls in the beginning or at the
end?). I'd assume at the end as the default behaviour - maybe add a property
to allow people to customize this.
