Preface

This module is one in a series of modules designed to teach you about the essence of Object-Oriented Programming (OOP) using Java with particular emphasison accessibility for blind students.

This module, along with several modules that follow provide the background information that you will need to understand the sound and audio programmingmaterial later in the course. You will need to study this material if you are new to Java programming.

On the other hand, if you already have Java programming experience, or if you are just curious, you may want to jump ahead to the module titled Jbs2000-What is Sound?

Prerequisites

As mentioned in an earlier module, in addition to an Internet connection and a browser, you will need the following tools (as a minimum) to work through the exercises in this and the following modules:

• An audio screen reader that is compatible with your operating system, such as the NonVisual Desktop Access program (NVDA), which is freelyavailable at (External Link) .
• A refreshable Braille display capable of providing line by line tactile output of information displayed on the computer monitor is recommended. Sucha display is described at (External Link) , is recommended.
• The Oracle Java Development Kit (JDK) (See (External Link) )
• Documentation for the Oracle Java Development Kit (JDK) (See (External Link) )
• A simple IDE or text editor for use in writing Java code.

The minimum prerequisites for understanding the material in this and the following modules include:

• A cursory understanding of algebra.
• An understanding of the material covered in the Programming Fundamentals modules that you will find in two formats at the following URLs. These modules provide fundamental programming concepts using the Javaprogramming language in a format that should be accessible.

The essence of OOP

My dictionary provides several definitions for the word essence. Among those definitions are the following:

• The property necessary to the nature of a thing
• The most significant property of a thing

Thus, this and several modules that follow describe and discuss the necessary and most significant aspects of OOP using Java -- theessence of OOP using Java. For the first few modules, I will provide that information in a high-level format, devoid of any requirement to understand detailed Java syntax. In those cases where an understanding of Java syntax is required, I will provide the necessary syntax information in the form of supplementary notes.

If you understand the fundamentals of computer programming described above , you should be able to read and understand the modules in this miniseries.
