Example text

As you start this book, be prepared to think in new ways, and to feel motivated to start coding for both fun and profit. Ruby has helped a lot of jaded developers become productive once again, and whether you’re a beginner to programming or one of those jaded programmers, it’s almost inevitable that you’ll see how Ruby can be both fun and productive for you. Last, if you’re coming from other modern scripting languages such as Perl, PHP, or Python, you might want to jump to Appendix A before reading Chapter 1.

Think about how you would create methods for the other Pet classes or the Pet class itself. Are there any methods that are generic to all pets? If so, they’d go in the Pet class. Are there methods specific to cats? They’d go in the Cat class. Everything Is an Object In this chapter, we’ve looked at how Ruby can understand concepts in the form of classes and objects. We created virtual cats and dogs, gave them names, and triggered their methods (the bark method, for example). These basic concepts form the core of object-oriented programming, and you’ll use them constantly throughout this book.

Type in the preceding code and give it a try if you like. However, creating the classes in this way would miss out on one of the best features of object-oriented programming: inheritance. Inheritance allows different classes to relate to one another and group concepts by their similarities. In this case, cats, dogs, and snakes are all pets. Inheritance allows you to create a “parent” Pet class, and then let your Cat, Dog, and Snake classes inherit the features that all pets have. Almost everything in real life exists in a similar structure to your classes.
