Study Guide Overview

This guide covers static and dynamic types of objects, focusing on how they are determined during object creation. It then explains method calling and polymorphism, illustrating how static and dynamic types influence which method is executed. The guide uses code examples to demonstrate the interaction between static/dynamic types and static/non-static methods.

#Static and Dynamic Types

Now that we have established a little bit about polymorphism in the last topic, let's talk some more about it. Every object has a static type and a dynamic type. Let's use the hierarchy tree from the last topic:
