Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: 0

That's not a compile time error, i.e. the error happened when you tried to run the program so it's a runtime error. Did you supply at least one command line argument to the program because it tries to read one, i.e. did you run your program as follows?

java Main <an argument goes here>

kind regards,

Jos

I've added code tags into your code segment. Please use code tags next time when you are posting code segment in the forum. Unformatted codes are really hard to read. If you don't know how to do that, please check in my forum signature. You can find the link to proper explanation.

Regarding your question, do you know what's doing in,

String mins_str = args[0];

line?
