Objects

Objects are created at run-time using the classes defined in the AOT. To create
an object from a class, the class has to be instantiated.
Instantiating a ClassObject instance methods can only be used when an object is instantiated from a
specific class. To instantiate a class, is to create a new instance of it. You can
have multiple instances of a class, meaning, you can have the same code running
multiple times. Think of how in Microsoft
® Word®, you can have two documents
open at the same time. They are both running the same program, but are two
separate instances of that program.
When you create a new object, call the new() method to execute the code when
the object is instantiated.

Once the class is instantiated, to execute a specific method from your code, use
the reference variable followed by a "dot" operator then the method name.

 myClass myClass;   
 myClass = new myClass();  
 myClass.myMethod();  
The objective of following lab is to instantiate a class, and then execute a method
from that class.
