Subject: differnce between .nil? , .empty?, .blank?

Hi
   Could you please tell me when to use .nil? , .empty?, .blank? .What
are the difference between them.. For example  I have
params[:company][:whichCompany]
And to check for it is null I first attempted all these and finally the
following worked
if !params[:company][:whichCompany].empty?

  So now really i am confused .Please tell me the differnce

Thanks in advance
Sijo
