title: How to check whether a int is not null or empty?
body: <p>I really dont know if this is possible or not.
  But I am strucking in a place where I want to check an int value is <code>null</code> or not, to call different methods.</p>
  
  <p>Is there any way to do it?</p>
  
  <p>Actually, variable comes from a browser with a <code>null</code> value.
  I cannot change the <code>int</code> declaration to <code>Integer</code>. Because it has it own consequences.</p>
  
  <p>Any suggestions?</p>
