private jsp servlets ..]" We explicitly told Ruby that KaraokeSong was a subclass of Song, but we didn't specify a parent class for Song itself. If you don't specify a parent when defining a class, Ruby supplies class Object as a default. This means that all objects haveObject as an ancestor, and that Object's instance methods are available to every object in Ruby.
private jsp servlets Back on page 18 we said that to_s is available to all objects. Now we know why; to_s is one of more than 35 instance methods in class Object. The complete list begins on page 351. Inheritance and Mixins Some object-oriented languages (notably C++) support multiple inheritance, where a class can have more than one immediate parent, inheriting functionality from each. Although powerful, this technique can be dangerous, as the inheritance hierarchy can become ambiguous.
private jsp servlets Other languages, such as Java, support single inheritance. Here, a class can have only one immediate parent. Although cleaner (and easier to implement), single inheritance also has drawbacks---in the real world things often inherit attributes from multiple sources (a ball is both a bouncing thing and a spherical thing, for example). Ruby offers an interesting and powerful compromise, giving you the simplicity of single inheritance and the power of multiple inheritance. A Ruby class can have only one direct parent, and so Ruby is a single-inheritance language.
