Ruby Fundamentals Training

Object-Oriented Programming Constructs in Ruby

Object-oriented programming languages include specific elements to make it easy to implement an object model in code. We look at the facilities in Ruby for implementing objects, and compare them to related facilities in C++ and Java. In this section you will learn how to:

• create Ruby classes and inherit from existing classes
• create Ruby fields and properties
• create Ruby methods
• set visibility of properties and methods to private, protected, or public
• create class methods, fields, and properties -- items similar to "statics" in other languages
• determine if a Ruby object is of a particular type, and/or "responds to" a particular message or method call

A Ruby Contact Manager

As a practical test of what you have learned, we design and implement a simple contact manager application in Ruby using object-oriented design and programming techniques. You will get hands-on experience in:

• creating an object model to represent a business problem
• coding Ruby classes to implement the model
• adding Ruby infrastructure to make the model useful as a running program
• reading and writing to/from the console and file system using Ruby
• processing (parsing and generating) XML
• iterative development

Prerequisites:

• Experience with any other programming language (e.g., Visual Basic, C, Javascript, Perl, etc.)
