Cattle Drive Problem 1

[Aman Singh]

Hi folks,

I just got done with the first problem of Cattle Drive (Printing a name 100 times).

I am getting the correct output, but do you guys see any issues with this code or something I can do to improve it. I know its a real small problem

It would print only 99 times.. not 100.

Hi Sri,

Thanks for the reply
I apologize I kept it that way. Any other issue?

[fred rosenberger]

why do you have this line:

int size = args.length;

[Sridhar Santhanakrishnan]

And you would have a java.lang.ArrayIndexOutOfBoundsException if no parameters are entered. So use the size variable and check.

[Aman Singh]

Hi fred,

I actually wanted to handle ArrayIndexOutOfBounds, but couldnt implement it.
How do I handle this condition if user doesnt enter any arguments?

[David Newton]

Check the length of the arguments array?

[Aman Singh]

Hi David,

Thanks
if length is zero, dont process.

or set a default value...or tell the user they did something wrong...or anything else you want!

There are some very specific rules when working with the cattle drive -- of which I am not sure if you are violating them.

Regardless, this topic is being moved to the cattle drive forum, to be sorted out there.
