Object Creation
The Sphere class is a blueprint for creating Sphere objects.
An object is an individual thing in the program created using a class and the new operator.

instance¶
One distinct occurance of an object whose state and behavior is defined by a class. Object and instance both mean the same thing and are used interchangeably.
new tells Java to create an instance of this class.
* We use the class name and parentheses () with the new operator to create the object.
- This tells Java to build a new object, with enough memory for all of the object's data.
- This is called instantiation.
instantiation¶
The creation of a new object with all its data, based on the definition in the class. Also known as construction.
