title: How can I pass null arguments to my Java main method using run configuration arguments in Eclipse?
body: <p>I'm trying to run a main method that requires four arguments, but the last one can be null (If #4 is null, use the string value in #2 as input.  If #4 is NOT null, use #4 as a file path and use the string in that file as input instead. Bad coding, I didn't write it).  However, I'm having trouble getting Eclipse to accept that fourth argument as null.  </p>
  
  <p>If I put anything on the fourth line, it takes it as a string.  If I put nothing, then it only processes three arguments.  </p>
  
  <p>Does anyone know how to get it to accept a null value through the run configuration arguments?</p>
  
  <p>Thanks in advance,</p>
