Oh I guess thats wrong then.

Of course you could start by checking for args.length == 0 and outputing an "error" message straight away.

She could also check if args.length == 0 and if so, ask the user if he would like to input a set of numbers now, then ask for how many, and ask for each number one at a time to be inputted...

Sure, if I were the user then I'd confirm and then state that I would like to enter
-42 numbers; then just wait ... ;-)

Like I said, it's impossible to avoid, but realizing this, simply add a if input is negative with a while loop that simply asks again for an input till it's positive (still trying to avoid spitting out the error, even though it's the same thing)...

bleh!

and also if input is a number and if input is a valid number ....?

Doesn't scanner class automatically check if you're asking for a nextInt() or nextDouble() or any number...?

Now you're talking. And what does it do if the input doesn't match?

Throw an error/exception, prints the stack automatically.. . are you still agreeing with me that despite my hatred for them it's impossible to avoid error/exception handling? I know, I know...

All in good fun ;)
