utils for notnulll

[tubin gen <fa...@gmail.com>]

I have  a form with start date and end date  fields,  form makes sense only
if both the fields are present,any one of tow is null it is not right , I am
wondering there is any   util which checks if both the values are not null ,

I can write the code to check if start date is not null and  end date id
null add error message , and vice versa , is there any such util present or
do I have to write one ?

Nope. Things like Lang's StringUtils.isEmpty (null or empty String)
can be useful here but you would need to handle the &&; and Validator
can be useful in a larger architectural sense.
