Lets say I have a string variable FirstName
. FirstName
can be null. I need to know if FirstName
exists or not.
Is it better to just use one variable: FirstName
and if FirstName
is empty assume that it doesn't exists
OR
Create two variables:
Boolean HasFirstName
and String FirstName
The benefits of this is I know positively that FirstName
doesn't exist but on the down side it creates two variables.
firstName == null
andfirstName == ""
