Learning Object-Oriented Programming

Chapter 6. Duck Typing and Generics

In this chapter, we will write code that we will maximize code reuse by writing code capable of working with objects of different types. We will take advantage of the different mechanisms to maximize code reuse in each of the three covered programming languages: Python, JavaScript, and C#. We will cover the following topics :

• Understanding parametric polymorphism and generics
• Understanding duck typing
• Working with duck typing in Python
• Working with generics in C#
• Declaring classes that work with one and two constrained generic types in C#
• Working with duck typing in JavaScript

Understanding parametric polymorphism and duck typing

Let's imagine that we want to organize a party of specific animals. We don't want to mix ...
