Join David Gassner for an in-depth discussion in this video Using member classes, part of Advanced Java Programming (2012).
In the world of object-oriented programming we use the term encapsulation to talk about hiding data.…In Java, you can hide data as private fields, but you can also create member classes that…are contained within other classes and those member classes can be the ultimate sort of…encapsulation. I'll show you how to implement member classes using this project named member…classes, which has a main class with the main method, and two supporting classes called Olive and OliveJar.…
In the initial implementation of this project, I'm creating an instance of the OliveJar class…and then saying that I want three Kalamata olives and then I'm looping through the olives…field of the OliveJar and reporting what olives are in the jar. I'll run the code and show…that in addition to the three Kalamata olives that I put in there, the OliveJar is putting…in it's own Golden olive. Now I'm going to re-factor this code.…Right now, the entire application can see the implementation of the olive class, but…I'd like to change it so that only the OliveJar can use this class and every other part of…
