Summary

Now, we know almost everything there is to know about methods, including parameters versus arguments, signatures, bodies, access specifiers, and return types. The one missing link is how methods relate to classes. The class-method relationship will be blown wide open in the much-trailed Chapter 8, Object-Oriented Programming, which is drawing ever closer. For now, there is a more pressing problem that needs solving.

Before we congratulate ourselves too much, we need to address the huge, elephant in the room – see the following screenshot:
