How to handle nulls when using Java collection sort

Question

When using Collection.sort in Java what should I return when one of the inner objects is null

Example:

Collections.sort(list, new Comparator

        

Answer 1

It depends, do you consider null as a big value or a low value.

You can consider most of the time that null < everything else, but it depends on the context.

And 0 would be a terrible return value here.
