Chapter 1. Concurrent Object-Oriented Programming

This book discusses some ways of thinking about, designing, and implementing concurrent programs in the Java™ programming language. Most presentations in this book assume that you are an experienced developer familiar with object-oriented (OO) programming, but have little exposure to concurrency. Readers with the opposite background — experience with concurrency in other languages — may also find this book useful.

The book is organized into four coarse-grained chapters. (Perhaps parts would be a better term.) This first chapter begins with a brief tour of some frequently used constructs and then backs up to establish a conceptual basis for concurrent object-oriented programming: how concurrency ...

More than 5,000 organizations count on O’Reilly

O’Reilly covers everything we've got, with content to help us build a world-class technology community, upgrade the capabilities and competencies of our teams, and improve overall team performance as well as their engagement.

Julian F.

Head of Cybersecurity

I wanted to learn C and C++, but it didn't click for me until I picked up an O'Reilly book. When I went on the O’Reilly platform, I was astonished to find all the books there, plus live events and sandboxes so you could play around with the technology.

Addison B.

Field Engineer

I’ve been on the O’Reilly platform for more than eight years. I use a couple of learning platforms, but I'm on O'Reilly more than anybody else. When you're there, you start learning. I'm never disappointed.

Amir M.

Data Platform Tech Lead

I'm always learning. So when I got on to O'Reilly, I was like a kid in a candy store. There are playlists. There are answers. There's on-demand training. It's worth its weight in gold, in terms of what it allows me to do.
