Murach’s Java Programming (5th Edition)
This is the 5th Edition of our best-selling core Java book. (There is a newer version). Since 2001, it has been used by thousands of beginning and experienced programmers to master the core Java skills that are needed to create desktop, web, and mobile applications. Now revised to cover Java SE 9 and updated throughout, it focuses on today’s best practices, including using an IDE for all phases of program development …a professional practice that most other Java books ignore.
College Instructors

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 an IDE
Starting from chapter 1, you’ll take advantage of the time-saving features that an IDE provides as you use NetBeans or Eclipse to create, compile, run, test, and debug Java applications. The book itself shows how to use NetBeans, but there’s a PDF in the free download for this book that shows how to use Eclipse.
Make sense out of object-oriented programming
Section 2, on object-oriented programming, cuts through the mystery of encapsulation, inheritance, and polymorphism so you can learn how to create and use sophisticated business and data access classes. It also shows you how to use two new features of Java 9, the module system and Project Jigsaw, to develop truly modular classes that are easier to use and deploy. At the end, 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, collections, generics, strings, dates, times, file I/O, exceptions, and more! Each chapter in this section is independent of the others, so you can add these skills to your resume whenever you need them.
Create user-friendly GUIs
Section 4 shows you the basics of using the JavaFX and Swing APIs to develop attractive graphical user interfaces (GUIs) that handle events and validate data. JavaFX is newer and offers more advanced features, but Swing has been popular for years and is more widely-used.
Work with databases like a pro
To complete your OOP training, section 5 shows you how to write database classes that map objects to a relational database. First, you’ll learn how to use SQL to work with SQLite databases. Then, you’ll learn how to use JDBC to work with any database.
Take your skills to a new level
Section 6 adds to your professional skills. So you’ll become proficient with the two most exciting features of Java 8, lambda expressions and streams. And you’ll learn how to use threads to make your applications run more efficiently.
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 mobile or web development…
This book is a favorite among developers who are moving into programming Android apps or Java web applications. Chapters 1-16 deliver the core Java skills that you need, whether you’re looking for a first course in Java or a refresher.
What’s NEW in this edition
This book has been updated from Java SE 7 to Java SE 9. Here’s a quick summary of all that’s new:
- New chapter on lambda expressions and streams
- New chapter on the Java 8 date/time API
- New chapter on JavaFX
- New coverage of the popular SQLite database
- New material on using Java 9’s JShell to interactively test code
- New material on using Java 9’s module system and Project Jigsaw
- New downloadable PDF that shows how to use Eclipse with this book
- New source code files in Eclipse format
What software you need
This book teaches you how to develop Java applications using:
- the Java Platform Standard Edition (Java SE)
- the top IDEs for Java programming: NetBeans (shown in the book) and Eclipse (covered in a downloadable PDF)
Although this book covers Java SE 9, 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 for free from the Oracle website. Likewise, you can download the IDEs for free from the NetBeans website or the Eclipse website.
Companion books for web and mobile 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). This book requires most of the skills that are presented in chapters 1-16 (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 book on that subject, Murach’s Android Programming (2nd Edition). Again, this book requires that you have most of the skills presented in chapters 1-16 of our Java Programming book.
What people say about this book
“If you’re a Java virgin like I was before reading this book, then you’re going to love it. I had a development environment up & running within half an hour and was dabbling with code 15 minutes after that!”
- Andy Bonner, vbcity.com
“One of the things I really like is that this book uses an IDE to teach Java to the next generation of programmers. A lot of books on Java focus on the language itself. This would have the appearance that an IDE plays no role in learning Java [but] any professional programmer will tell you that an IDE is absolutely essential in making you more productive.”
- John Yeary, Java Evangelist
“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.”
- Posted at an online bookseller
“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
“I love the 2-page style that you use in your Java book. It is such a great way to organize the lessons. I already have another Murach book picked out for when I am done with this one.”
- Dave Merton, Director of Development, Connecticut
“Another thing I like is the exercises at the end of each chapter. These exercises are a great way to reinforce the main points of each chapter and force you to get your hands dirty.”
- Hien Luu, SD Forum/Java SIG
“If I’d seen this book first, I would not have wasted money (and time) on 6 other books!”
- Posted at an online bookseller
“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
