The essence of OOP is modelling abstractions, using classes and objects. The hard part in this endeavor is finding the right abstraction. A class denotes a category of objects, and acts as a blueprint for creating such objects. A class models an abstraction by defining the properties and behaviors for the objects representing the abstraction. An object exhibits the properties and behaviors defined by its class. The properties of an object of a class are also called attributes, and are defined by fields in Java.
Other objects) only need to know the contract of an object, and not its implementation, in order to avail themselves of the object’s services. As an example, we will implement different versions of a class that models the abstraction of a stack that can push and pop characters. The stack will use an array of characters to store the characters, and a field to indicate the top element in the stack. 1, which models the abstraction. 1a. 1. Its intention is to illustrate the salient features of a class declaration in Java, and not the effective implementation of stacks.
