I have an object with some dates and I'd like to return them in the getter. The problem is that i need to do `Date.toString();` because I have to print them, and when the date is null I get a `NullPointerException`. 

I was thinking about returning the date 0/0/0 when the date is null, but I don't know how to set this value. Is there any way? Just like `new Date(0)` returns the **1970-01-01-00:00:00**, is there anything similar to this but to return 0/0/0?

Thanks!
