Ex: -Radio Bank Account A class posterior be utilise to create differe nt objects An object represents something w! ith which we piece of tail interact in a program -Has attributes and behaviors -Provides a prayer of service that we finish tell it to perform for us -The service are defined by methods in a class that defines the object Inheritance -one class can be used to derive another -classes can be form into in heritance hierarchies ACCOUNT ? ?? charge account bank account ?...
