          You'd have to post the code.

          But what is so hard to understand here? Apparently you have some code which tries to parse a String into an integer (I'm guessing when read from the command prompt / shell), but in this case it is given an empty string and an empty string cannot be transformed into a number. Hence the exception. Its not a code error, it just a regular problem that can happen in an application that you need to deal with somehow.
