I love your Java book. It cuts right to the essential information, providing the perfect balance between too many details and too little information. I bought another well-known Java book, but I spent several hours trying to learn what I learned from your book in about 45 minutes."

What to expect from this book

Get a quick start

You’ll be writing your first complete Java applications at the end of chapter 2!

Build realistic applications

By the end of chapter 5, you’ll know how to use Java classes, objects, and methods to write bulletproof applications that use custom methods to validate user input. That gets you off to a fast start in Java whether you’re a beginner or have years of programming experience.

Work more efficiently by using NetBeans

Starting from chapter 1, you’ll take advantage of the time-saving features that an IDE provides as you use NetBeans to create, compile, run, test, and debug Java applications.

Object-oriented programming made clear

Section 2, on object-oriented programming, cuts through the mystery of inheritance, polymorphism, and the factory pattern so you can learn how to create and use sophisticated business and data access classes. At that point, you’ll know how to develop real-world, object-oriented, business applications.

Expand your core Java skills

In section 3, you’ll learn more of the core Java features that you’ll use all the time, like how to work with arrays, dates, strings, exceptions, enhanced for loops, try-with-resources, and more! Because each chapter in this section is independent of the others, you can add these skills to your resume whenever you need them.

Create user-friendly GUIs

Section 4 shows you how to use the popular Swing GUI Builder that comes with NetBeans to develop GUI applications. Here, you’ll learn how to handle events, validate data, and populate objects to create applications that aren’t just useful, but easy-to-use as well.

Work with files and databases like a pro

To complete your OOP training, section 5 shows you how to write data access classes that store the data for objects in a file or database. Here, then, you’ll learn how to: work with text, binary, and XML files; embed an Apache Derby database in an application; and use JDBC to work with any database.

Take your skills to a new level

Section 6 shows you how to work with threads and how to deploy your finished applications using executable JAR files or Java Web Start.

Who this book is for

This book is for anyone who wants to learn the core features of the Java language. It works:

  • if you have an aptitude for problem-solving but no programming experience at all
  • if you have programming experience with another language
  • if you already know an older version of Java and you want to update your skills
  • if you’ve already read 3 or 4 other Java books and still don’t know how to develop a real-world application

If you want to go into Android programming or Java web development…

This book is a favorite among developers who are moving into programming Android apps or Java web applications. Chapters 1-14 and 19 deliver the core Java skills that you need, whether you’re looking for a refresher or a first course in Java.

What’s new in this edition

The big news in this edition is that it now teaches Java programming using the NetBeans IDE. Today, no professional programmer should miss out on the time-saving features of an IDE, and NetBeans is a popular choice that's free, easy-to-use, and powerful. And because NetBeans works on the Windows, Mac, and Unix/Linux operating systems, this book is less Windows-centric than previous editions have been.

There are also new chapters on debugging and deployment, and the GUI section now features the use of the NetBeans Swing GUI Builder. In terms of the Java language itself, there aren't a lot of significant changes in Java SE 7, but new features have been added whenever they’re useful, and of course, the technical content has been updated throughout.

What software you need

This book teaches you how to develop Java applications using:

  • the Java Platform Standard Edition (Java SE)
  • NetBeans, a popular, easy-to-use IDE

Although this book specifically covers Java SE 7, almost all of the core features will work with all previous releases of Java...and will continue to work with future releases as well.

You can download Java and its documentation for free from the Oracle website. Likewise, you can download NetBeans for free from the NetBeans website. To make this easier for you, Appendix A (for Windows) and Appendix B (for the Mac) explain the procedures you will use to download and install both pieces of software.

Companion books for web and Android developers

Since web programming is one of the primary uses of Java, we also offer a book on web programming called Murach’s Java Servlets and JSP (3rd Edition). It shows you how to use Java servlets and JavaServer Pages as you develop professional web applications. As you read that book, you’ll discover that Java web programming requires most of the skills that are presented in chapters 1-14 (sections 1-3) of our Java Programming book.

Another primary use of Java today is developing Android apps for tablets and smart phones. So we also offer a great first book for on that subject, Murach’s Android Programming. Again, like our Servlets and JSP book, this book assumes that you have the skills that are presented in chapters 1-14 of our Java Programming book.

What people say about this book

“Finally there is a Java book for serious programmers doing real life business applications.”
- Donna Dean, IS Trainer, Chicago, Illinois

“I bought your Java book a week ago and I am already writing useful programs, not ‘toys!’”
- Richard Cooper, Programmer

“If I’d seen this book first, I would not have wasted money (and time) on 6 other books! This one is highly organized, clear, and very effective as a learning tool.”
- Posted at Amazon.com

"I bought this book to brush up on my Java programming skills in preparation for doing some Android programming. This book brought me up to speed really fast, and it even has a chapter on XML, which is used in Android."
- Posted at an online bookseller

"I’m reading the part of the book that discusses the nio package. The information is so clear, it beats what I read in the Java tutorials on the Oracle web site. Once again, a Murach book adds clarity that’s hard to find elsewhere."
- Steve, Programmer, Denver, Colorado

"Ever have someone come in your office with a Java question, and you reach for a certain book that you know has the answer in it? When needing assistance with the core features of Java, Murach’s Java Programming is the resource that supplies these answers, both quickly and completely. If this book isn’t on your bookshelf, you should get it there."
- Robert Liguori, Tech Center Java User Group

“Terrific - Fantastic - Superlative! WELL worth several times the purchase price.”
- Posted at an online website

Murach's Java is now my go-to source for reference and learning and brushing up, well above and beyond the other books in my collection.”
- Jeff Salter, Sacramento Java Users Group (SacJUG)

 “The style is clean, very user friendly, and simple. The narrative is totally accurate and focuses on important issues; it is not dumbed down. This book is a winner!”
- Dr. Richard Wiener, Editor-in-Chief, Journal of Object Technology
