Lesson 1 - Declarations and Access Control

A template that describes the kinds of state and behavior that objects
of its type support.

At runtime, when the Java Virtual Machine (JVM) encounters the
new keyword, it will use the appropriate class to make an object which is an instance of that class. That object will have its own state, and access to all of the behaviors defined by its class.

Each object (instance of a class) will have its
own unique set of instance variables as defined in the class. Collectively, the values assigned to an object's instance variables make up the object's state.

When a programmer creates a class, she creates methods
for that class. Methods are where the class' logic is stored. Methods are
where the real work gets done. They are where algorithms get executed, and data gets manipulated.

Allows the code in one class to be reused in other class.

General class (more abstract), that will be extended by subclasses.

Extends a superclass. By inheriting from superclass, a subclass is automatically given accessible methods defined by superclass, but is also free to override superclass bethods.
