And if the JavaTM programming language is your first experience with an object-oriented language you are probably wondering what all the talk is about. You already know a little about object-oriented programming because after working the example programs in Java Programming Language Basics Part 1 and Part 2 you are somewhat familiar with the object-oriented concepts of class object instance and inheritance plus the access levels public and private. But mostly you have been doing object-oriented programming without really thinking about it. And that is one of the great things about the Java programming language. It is inherently object oriented. To help you gain a deeper understanding of object-oriented programming and its benefits this lesson presents a very brief overview of object-oriented concepts and terminology as they relate to some of the example code presented in this tutorial. Object-Oriented Programming Defined Classes Objects Well-Defined Boundaries and Cooperation Inheritance Polymorphism Data Access Levels Your Own Classes Program Improvements More Information Object-Oriented Programming Defined Object-oriented programming is a method of programming based on a hierarchy of classes and well-defined and cooperating objects. Classes A class is a structure that defines the data and the methods to work on that data. When you write programs in the Java language all program data is wrapped in a class whether it is a class you .
