Why do I get runtime error (NZEC)?

[m_satydeep]

Hi
I am submitting a program written in JAVA which compiles and runs fine on my computer. But on submitting it, I get the error 'runtime error (NZEC) '. Why is this happening? My program expects a couple of command line arguments(the input and output test files). Is this someway related?

Regards

Hi,
input and output ought to be consecutively read from standard input and printed into standard output. No arguments are passed to programs in SPOJ. See spoj.pl/tutorials/USERS/ from more details.
On page mentioned above also description of error codes can be found. NZEC occurs when your program exits with non-zero code: in C "return 0" would fix it; in Java - well, you must be doing something that causes your program to terminate with non-zero code.
