The first option will create new objects (and later garbage)

If performance matters, the second option may be preferable. If in doubt, use the approach which is clearest and simplest to you.

BTW Another option is to use

private BugDecimal creditBalance1 = BigDecimal.valueOf(0);

This will use a cache of values where possible (and create new objects if not)

In the big scheme of things it doesn't matter which one you use. But since there already is a constant for zero, you might as well use it.
