Thankyou for any suggestion!

You need to pass the month number as an argument, like this for the
length of March:

java cl_gm 3
31

If you just run

java cl_gm

the String array passed to the main method as args[] will be empty, so
args[0] will be outside the array, and the
ArrayIndexOutOfBoundsException is thrown because of this.

You may wish to familiarise yourself with the javadoc for the exception
<http://java.sun.com/j2se/1.5.0/docs/api/java/lang/ArrayIndexOutOfBoundsException.html>
