Object-Oriented vs. Functional Programming 

Object-Oriented vs. Functional Programming pdf

Book Description

The schism between functional and object-oriented programmers is a false binary. The first group argues that FP is superior for a multicore world, while the second insists that OOP is better at matching technical solutions to business problems. However, this O’Reilly report explains that this is not an either-or proposition.

This book discusses similarities between these programming paradigms and points out that FP and OOP are moving closer. One prominent example is lambda expressions in Java and other OOP languages such as C#, C++, and Swift.

By following examples written in Java, you will learn to

  • Learn how lambdas (aka anonymous functions) make OOP languages better suited for dealing with parallelism and concurrency.
  • Understand how SOLID—OOP’s five basic programming principles—maps to functional languages and paradigms.
  • Explore some of the most common OOP design patterns and how they exist in the functional world.
