I made this program to divide by N for each iteration of the while loop, and in doing so it would take the sum of every iteration and print it to the line, the only problem is that the answer I receive is this.

Sum is: Infinity

If anyone knows why I'd love to know. Also, if anyone has any input on how to do this better too, I would love to know.

Thanks.

You have initialise z=0

Hope this helps ...

I'd suggest turning x and N into ints. Check out this about some problems with floating point numbers.

But then make sure you are never dividing by 0!

The only division here is 1.0 by z, and z is already an int.

Or do you mean this as a warning for future references that any division with no floats or doubles will throw a ArithmeticException?

Yes that will lead to an exception.
But that brings up an question, why separate behavior for int and double?

Sorry for delay: yes, I meant a warning against the ArithmeticException.
