I've tried just about everything I know to get the array to NOT print the location of the object and it's contents. I have overridden the toString() method for each object and I still get nothing back. Help is appreciated Thanks

Not in the code you've posted you haven't.

I thought I did. Shouldnt showData() work ?

If you call showData, then that will work, but you are calling toString. An overriding method has to have the same signature (including the name) as the method it is overriding.

Thanks I did a toString() method and I got the output I needed thanks!
