Thanks, but:
equals doesn't compare: it only returns true or false, not -1, 0 and 1.
I use it in a custom Comporator to sort a List with Collections.sort(),
The CompareToBuilder is a bit overkill: I just need to compare 2
strings, null safe.
Not that it's hard or a lot to write :) just wanted to say I think it's
missing from ObjectUtils.

For more generic handling of comparison checking:

Subject: [lang] null-safe compareTo method
Is there a null-safe compare method?
I need to compare 2 strings:
- both null => equal
- one null => that one is smaller
- neither null => a.compareTo(b)
Else I 'd propose something like:
ObjectUtils.compare(Comparable a, Comparable b)
