Excerpt: Subtype polymorphism, almost universally called just polymorphism in the context of object-oriented programming, is the ability to create a variable, a function, or an object that has more than one form. The word derives from the Greek q q meaning qhaving multiple forms.q This article is an accessible introduction to the topic, which restricts attention to the object-oriented paradigm. In principle, polymorphism can however arise in other computing contexts and it shares important similarities to the concept of degeneracy in biology. The purpose of polymorphism is to implement a style of programming called message-passing in the literature, in which objects of various types define a common interface of operations for users. In strongly typed languages, polymorphism usually means that type A somehow derives from type B, or type C implements an interface that represents type B. In weakly typed languages types are implicitly polymorphic. Operator overloading of the numeric operators (+, -, *, and /) allows polymorphic treatment of the various numerical types: integer, unsigned integer, float, decimal, etc.; each of which have different ranges, bit patterns, and representations. Another common example is the use of the q+q operator which allows similar or polymorphic treatment of numbers (addition), strings (concatenation), and lists (attachment). This is a lesser used feature of polymorphism. The primary usage of polymorphism in industry (object-oriented programming theory) is the ability of objects belonging to different types to respond to method, field, or property calls of the same...Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online.
