FAQ

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 is public; default is like being private within its 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 for the code that uses it.
