1. Chapter 7
Classes & Objects

2. Class A class defines a particular kind of object.
Each class is a blueprint that tells Alice exactly how to create and display an object.
Classes begin with a capital letter.

3. Objects
When an object is created and displayed, we call this instantiating the class because an object is an instance of that class.
Object names begin with a lowercase letter.

4. Object-Oriented Programming Concepts
Encapsulation - lets you create a program (class) that describes data and methods that you want to use as a template to create objects. 
Inheritance - enables you to create a class that is similar to a previously defined class, but one that still has some of its own properties. 
Polymorphism – allows you to create new objects that perform the same methods as the base object but which perform one or more of these functions in a different way.

5. Declaring Objects Cow cow1 = new Cow ( ……..);
Adult emily = new Adult ( …..);
Button clearButton = new Button ( );

6. Constructor
A constructor is a method with the same name as the class (including case sensitivity).  
A class can contain several constructors to provide a variety of means for initializing objects of that class. 
MyFishy nemo =  new MyFishy( );
public MyFishy( ) { }
