Before get into the answer, we gotta know something
prior...! "JavaBeans".
JavaBeans are java classes that have properties. For our
purpose, think of properties as private instance variables.
since they're private, the only way they can be accessed
from outside of their class is through 'methods'in the
class.
The methods that change a propertiy's value are called
setter methods, and the methods that retrieve a property's
value are called getter methods.
