Hello,
First of all change this line
> String []arr = new String[7];
With
> String []arr = new String[args.length];
This will male tour program able to run with any args passed.
Secondly change
> for(int i = 1; i<arr.length;i++)
with
> for(int i = 0; i<arr.length;i++)
In this way it should work.
I also suggest to always use {} in your for loop, even with just 1 line of code
to male your code more easy to read.
You can also add a for loop to print args values, to verify what is really
passed to your program.
