Define the field myName to be of the type String within the Student class as shown here: Class student { String myName; Student(String name) { } String getName() { return "Jane Doe"; } } In the constructor body, assign the constructor's parameter name to myName: Student(String name) { myName = name; } Finally, return the field from the getName method (instead of the String literal "Jane Doe"). String getName() { return myName; } JUnit should still be open, showing the comparison failure and red bar.

30 additional behaviors and attributes. An AlarmDoor provides the ability to trigger an audible alarm when activated and is also able to operate as a secure door. Since the secure and release behaviors of the AlarmDoor are the same as those in the Door class, the AlarmDoor can designate that it is inheriting from the Door class and need only provide specification for alarm activation. Inheritance provides the AlarmDoor class with the ability to reuse the secure and release behaviors without having to specify them.
