Question

I have a method which returns a string. It can be in normal operating conditions that a blank string or null is returned. However, is it a good coding practise to return null or "" from this method?

Answer 1

Yes, in that situations I prefer returning null to show that string is not found. Empty string has usually used for showing empty result.

Alternative way is to throw some Exception, but as programmer I don’t find usable to work with Exceptions. Returning null is much better.
