Did you pass in a command line argument when running it?

The code is not the problem per se ( although a simple check in the code could stop this problem ), do a google search for “command line arguments in jCreator”, this should hopefully point you in the right direction.

Solution 1

Ty changing your code from

public static void main(String args[ ] )

to

public static void main(String[] args)

That should solve the problem.
