Packages and Accessibility (Visibility)
By now, you are already quite familiar with packages. In this chapter, we will complete its description and then discuss different levels of accessibility (also called visibility) of classes and class members – methods and fields. It all will come down to the key concept of object-oriented programming – the encapsulation – and lay the foundation for our discussion of object-oriented design principles.
In this chapter, we will cover the following topics:
