Sams Teach Yourself Java in 24 Hours, 7th Edition (2014)

Introduction

As the author of computer books, I spend a lot of time lurking in the computer section of bookstores, observing the behavior of readers while I’m pretending to read the latest issue of In Touch Weekly magazine.

Because of my research, I’ve learned that if you have picked up this book and turned to the introduction, I only have 13 more seconds before you put it down and head to the coffee bar for a double-tall-decaf-skim-with-two-shots-of-vanilla-hold-the-whip latte.

So I’ll keep this brief: Computer programming with Java is easier than it looks. I’m not supposed to tell you that because thousands of programmers have used their Java skills to get high-paying jobs in software development, web application programming, and mobile app creation. The last thing any programmer wants is for the boss to know that anyone with persistence and a little free time can learn this language, the most popular programming language on the planet. By working your way through each of the one-hour tutorials in Sams Teach Yourself Java in 24 Hours, you’ll be able to learn Java programming quickly.

Anyone can learn how to write computer programs—even if you can’t program a DVR. Java is one of the best programming languages to learn because it’s a useful, powerful, modern technology that’s embraced by programmers around the world.

This book is aimed at nonprogrammers, new programmers who hated learning the subject, and experienced programmers who want to get up to speed swiftly with Java. It uses Java 8, the brand-new version of the language.

Java is an enormously popular programming language because of the things it makes possible. You can create programs that feature a graphical user interface, design software that makes the most of the Internet, connect to web services, create an app that runs on an Android phone or tablet, and more.

This book teaches Java programming from the ground up. It introduces the concepts in English instead of jargon with step-by-step examples of working programs you will create. Spend 24 hours with this book and you’ll be writing your own Java programs, confident in your ability to use the language and learn more about it. You also will have skills that are becoming increasingly important—such as network computing, graphical user interface design, and object-oriented programming.

These terms might not mean much to you now. In fact, they’re probably the kind of thing that makes programming seem intimidating and difficult. However, if you can use a computer to create a photo album on Facebook, pay your taxes, or work an Excel spreadsheet, you can learn to write computer programs by reading Sams Teach Yourself Java in 24 Hours.
