What is the difference between a static variable and A static variable is shared by all objects of a class. Every object has its own
an instance variable? version of an instance variable.
What is decompostion? A design strategy that breaks a task down into several subtasks.
What is the difference between an accessor method An accessor method returns data contained in an instance variable. A mutator
