Class-level Methods and Inheritance

Although our classes today and tomorow will be distracted by the exciting activities for the Christmas Concert you should be working concentrated to get your exercises completed and to set your mind on something new.

The new concept we are learning about are class-level methods as presented in section 4.3 of our textbook. Class- level methods are new methods that extend an already existing class and make it more powerful. Objetcs of the extended class can perform actions of all original methods and of the the newly created ones.
