If they are being called from outside the class, they must be public.

>In the same class, I created a private method. Then, I overloaded the method so it could also accept a different type for the parameter. So, the first declaration accepts an integer. The overaload declaration accepts a string. When running the application, I got an error telling me that the method was not found. I had to make them Public so to have it work. Why is that?
