I tried a simular solution, and just got "read only" error for the list.
So I ended up creating a whole new list. I was using foreach instead of for.

I solved this the same way except i converted the numberString.charAt(i) to an int before using it in the if statment and used the 5 as an int. I did not think that it would know what to do with the 5 as a char. Clearly I did not need to do that. I guess my question is how does java know?

Thank you sir. do you know why it fails with == if they are essentially the same thing?
