Lesson Review

In this lesson, we covered:

• What an object is and how we interact with an object's state and behavior.
• The distinction between a class and an object.
• How to define a class.
• How to work with objects, including how to access an object's state by invoking methods on those objects.
• What garbage collection is and why it is an important aspect of Java's memory management.

In the rest of the course, we will be using the fundamentals learned here to build powerful Java applications.
