null checks

Hi all,

While designing an application, what are the basic guidelines for the following:

1. when to make a NOT NULL check on objects.

2. when to throw an exception in case of an object being null, in a use case flow.

3. when should a method return null and when should it throw an exception instead?


Thanks in advance.
