资源说明：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 Soap
Opera Digest magazine.
Because of my research, I’ve learned that if you have picked up this book and turned to this
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, server programming, and Android
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 companies around the world.
This book is aimed at non-programmers, new programmers who think they hate this stuff, and
experienced programmers who want to get up to speed swiftly with Java. It uses Java 9, the latest
and greatest 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, connect to web services, run on
an Android phone or tablet, and more.
This language turns up in some amazing places. One of them is Minecraft, the gaming
phenomenon written entirely in Java. (In this book you learn how to create Java programs that
run in that game alongside creepers and zombie pigmen!)
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 Internet computing, graphical user interface design, app
creation, 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.
