I have spent over a WEEK trying to figure out why my code isn't working. It's a long code, I will post it all but I will break down the code as I explain.
First off, I have called double[] arrays and then initialized them later on in the program on certain steps. What problem is that even though they are initialized, later on in the code, it's telling me that the double[] I'm requesting is NULL, as if it didn't know that I have already done all that and added elements to it. Here's the program.....
