For each instance variable, a getter method returns its value while a setter method sets or updates its value. Getters and setters are also known as accessors and mutators, respectively. By convention, getters start with `get`, followed by the variable name, with the first letter of the variable name capitalized. Setters start with `set`, followed by the variable name, with the first letter of the variable name capitalized.
