To find the length of an array you do computerarray.length, that's what you are after here I believe.
For strings you can do string.length() as well.

I'll tell you, that's one thing I do like about Java, the size of a object is nicely packaged with the object itself. In C/C++ it's very messy, and you can't really return an array and then go array.length on it :-(

(Mind you that's only 1 thing I like about Java vs. C++ and 99 other things I hate in Java versus C++, so it doesn't count for too much!)
