Foreword

I suggested to my brother Todd, who is making the leap from hardware into programming, that the next big revolution will be in genetic engineering.

Introduction

Like any human language, Java provides a way to express concepts. If successful, this medium of expression will be significantly easier and more flexible than the alternatives as problems grow larger and more complex.

Prerequisites

This book assumes that you have some programming familiarity; you understand that a program is a collection of statements, the idea of a subroutine/function/macro, control statements such as “if” and looping constructs such as “while,” etc. However, you might have learned this in many places, such as programming with a macro language or working with a tool like Perl. As long as you’ve programmed to the point where you feel comfortable with the basic ideas of programming, you’ll be able to work through this book. Of course, the book will be easier for the C programmers and more so for the C++ programmers, but don’t count yourself out if you’re not experienced with those languages (but come willing to work hard). I’ll be introducing the concepts of object-oriented programming and Java’s basic control mechanisms, so you’ll be exposed to those, and the first exercises will involve the basic control-flow statements.

DevOps is a methodology that unites the often separate functions of software development (Dev) and production and operations (Ops) into a single, integrated, and continuous process. DevOps is about breaking down the barriers between Dev and Ops. It leverages people, processes, and technology to stimulate collaboration and innovation across the entire software development and release process. Dev and Ops should always be part of an integrated process, but that's not …
