Join David Gassner for an in-depth discussion in this video Navigating inheritance trees, part of Advanced Java Programming.
Java greatly depends on the use of inheritance to manage the relationship between different…classes and the Reflection API gives you tools that let you walk up the inheritance tree.…Once you have an object that you have a reference to you can walk up to its super class and…to its super class all the way up to the top level class object.…I'll show you how to do this in the project named Walk Inheritance.…In this version of the project I have the Olive class.…
The Olive class doesn't have an extends keyword.…So therefore by default it extends object and then I have three subclasses, Kalamata,…Ligurio, and Picholine, and each of these classes extends the Olive class.…So we have essentially a three-level inheritance tree, Picholine, Kalamata, and Ligurio are siblings.…They share a super class of Olive and Olive has a super class of object.…I'll go back to the main class into the main method, and I'll start my coding by creating…an instance of the Ligurio class, but I'm not going to be specific about its type.…
