Mutator (Setter) Methods
Sets the value of an instance variable.
Method header includes formal parameters.
Formal parameters must be typed.
Formal parameters act like local variables in the method body.
Method call includes argument expressions.
When method is called, formal parameters are bound to values of corresponding actual arguments.
Note, two ways a variable can get a value:
Local variable: Be assigned a value in an assignment statement.
Formal parameter: Be bound to a value in a method call.
