Overview of this book

We have reached a point where machines are not getting much faster, software projects need to be delivered quickly, and high quality in software is more demanding as ever. We need to explore new ways of writing software that helps achieve those goals. Clojure offers a new possibility of writing high quality, multi-core software faster than ever, without having to leave your current platform. Clojure for Java developers aims at unleashing the true potential of the Clojure language to use it in your projects. The book begins with the installation and setup of the Clojure environment before moving on to explore the language in-depth. Get acquainted with its various features such as functional programming, concurrency, etc. with the help of example projects. Additionally, you will also, learn how the tooling works, and how it interacts with the Java environment. By the end of this book, you will have a firm grip on Clojure and its features, and use them effectively to write more robust programs.

Chapter 4. Collections and Functional Programming

We are now comfortable with using Java code from our Clojure programs, and we also know how to expose our Clojure programs with a Java API. However, we need to take a deeper look at Clojure and its true nature, which is functional programming.

In this chapter, we will cover the following topics:

  • Basics of functional programming

  • Persistent collections

  • Sequential and associative collections

  • The sequence abstraction

  • Collection types

  • Applying functional programming to collections
