Frequently asked questions

1. What is wrong with this class declaration?

      private class someClass{
            // class implementation goes here
      }

   There are no private classes. Classes can be public or default. Public classes are public; default classes are private within their own package.

2. What is encapsulation?

   Encapsulation is how we contain our variables, code, and methods in a manner that exposes just the parts and functionality we want to other code.
