I assumed it was something of that nature, but I do know it was not binary of hexadecimal as I am familiar with each. This is what went to the file:...

Thanks. At first, it seemed like a problem. But using readDouble it works as it should, I was just curious as to what was in the actual text file. Using String the text file is intelligible. Again, a...

file.seek(inputFile.length());
file.writeDouble(randomInt);...

How do I convert a hexadecimal number to binary keeping the leading zeros? For the conversion itself I am using:

Thanks for your assistance.

I have revised the code in my previous post - actually tweaking the teacher's suggestion to fit a particular program - and now have a new problem. I get the following error (it actually prints it...

I am trying to test the logic of a particular method included in a project I am working on and so I have created a simple 3 by 3 Latin Square with which to do so. The basics of the program work fine,...

Thanks, I appreciate it. Now my program works fine, I had a feeling I was overlooking something obvious. Also, I actually was not getting an error message, I was getting the opposite of the results I...
