What this book does for your students

This book focuses on what a beginning Java programmer needs to know. The Table of Contents shows how the content is structured. But briefly, here‘s how the content works for your students:

It gets them off to a quick start

By the end of chapter 2, your students will be writing their first complete Java applications that get input, perform calculations, and display output.

It shows them how to build realistic applications

By the end of chapter 9, your students will be writing object-oriented applications that validate user input and use files to store their data.

It helps them learn faster by using an IDE

Starting from chapter 1, your students will take advantage of the time-saving features that an IDE provides as they use NetBeans or Eclipse to create, compile, run, test, and debug Java applications.

It teaches them OOP in a practical and clear way

Chapter 7 introduces your students to object-oriented programming (OOP), including the concept of encapsulation. Then, chapters 10 and 11 explain inheritance and polymorphism in a practical way that cuts through the mystery and confusion these subjects can cause. This provides the foundation that your students need to develop real-world, object-oriented, business applications.

It shows them how to create user-friendly GUIs

Section 3 shows how to develop attractive graphical user interfaces (GUIs) with JavaFX, a modern library that’s designed to replace the aging Swing library.

It lets them master essential professional skills

Section 4 presents more Java skills that your students will use all the time, like extra skills for working with strings, collections, lambdas, recursion, algorithms, dates, times, and databases. Each chapter in this section is independent of the others, so you can teach these chapters in whatever sequence you prefer.

It shows them how to work with databases

Chapter 19 shows your students how to write database classes that map objects to a relational database. First, they’ll learn how to use SQL to work with a SQLite database. Then, they’ll learn how to use JDBC to work with any database.

It prepares them for web and mobile development

By the end of section 2, your students will have the foundation in Java programming that they need to learn how to develop applications for the web or mobile devices. So, they’ll be ready for other courses that show how to use Java to develop web applications or Android apps.

Why your students will learn faster and better with our book

We’ve specifically designed this book to help your students learn Java faster and better than they ever could before. Here are a few of the ways it does that:

  • There are two ways to simplify material: Avoid all complications or present the material in the right order, at the right pace. The no-complications approach doesn’t give students a true view of how Java programming works, so we present each piece slowly and methodically in section 1, building skills and confidence. Then, after the foundation is in place, the rest of the book picks up the pace.
  • All the material is in our distinctive paired-pages format, where each topic is presented in a two-page spread: the examples and reference material are on the right-hand page with additional explanation and perspective on the left. In today’s fast-paced world, it’s the ideal format for students who want to read less, do more, and pick up information on demand. Students love it!
  • Besides fitting students’ learning style, the paired-pages format also helps your students do their assignments and prepare for tests by making it easy for them to (1) review what they’ve learned and (2) refresh their memories on how to apply their new skills.
  • This book presents dozens of complete applications. In each chapter, the applications start simply to illustrate the new concepts and skills, but then show the new skills in the context of real-world programming. We have long felt that these applications are essential to effective learning, and no other publisher does this the way we do. Yes, other books present complete applications too, but when the applications are trivial, they limit what the students can be expected to learn.

What software your students need

  • Java Standard Edition (Java SE)
  • NetBeans or Eclipse

Although this book covers Java SE 17, the code it presents will work with future versions of Java. In addition, this book clearly notes which features have been added since SE 9, which makes it possible to use this book with earlier versions too.

Using the time-saving features of an IDE is the easiest and best way to learn Java. That’s why this book shows how to use NetBeans and Eclipse, the two most popular IDEs for Java development.

Appendix A (Windows) and Appendix B (macOS) explain how to install the software, all of which is free.

What’s new in this edition

This book has been updated from Java SE 9 to Java SE 17, which is the current long-term support (LTS) release. As part of this update, we have streamlined this book to do a better job than ever of setting the right pace for a beginning Java student.

New book features

  • Eclipse coverage has been integrated into the book
  • Scanner object coverage has been simplified to make it easier and less error-prone for students to get input from the console
  • Array and array list coverage has been simplified and is presented earlier to make the book applications more realistic and interesting
  • File I/O coverage has been simplified and is presented earlier to make the book applications more realistic and interesting
  • JavaFX coverage has been expanded and is presented earlier to engage students by creating visually pleasing graphical user interfaces
  • Recursion and algorithm coverage has been added so students can learn about these important programming concepts

New Java features

  • Type inference lets you write code that’s more concise and easier to maintain
  • Arrow labels provide a more concise and less error-prone way to write switch statements
  • Switch expressions provide a more concise way to write switch statements that set the value of a variable
  • Pattern matching with the instanceof operator provides a more concise way to get objects that match a specified type
  • Records provide a concise way to code immutable objects that you can use to transfer data
  • Sealed classes provide a new way to control how inheritance hierarchies work

What people say about this book

“I love this book. It was the required text for my Java class and I'm glad. It's very concise, very easy to follow. The left page will be a detailed description of the figure on the page to the right, along with a breakdown of major takeaways from that section.”
- Posted at an online bookseller

“I initially rented this book for a crash course on Java GUI. I liked it so much that I ended up buying a copy.”
- Posted at an online bookseller

“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 focus on the language itself [as though] an IDE plays no role in learning Java. Any professional programmer will tell you that an IDE is absolutely essential in making you more productive.”
- John Yeary, Java Evangelist

“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

“I loved the way this book is set up. We used this in my Java Programming class, and it just makes everything so much easier and clearer.”
- Posted at an online bookseller

“I've most recently used the Java book to supplement my (rather terrible) textbook for a recent Java class at a local college. I made an A in the class, which wouldn't have been possible with the required textbook alone.”
- IT Manager, North Carolina

“The beauty of Murach books is that they are broken into what I call 'mini lessons.’ I can look at a chapter and decide it has 14 mini lessons, and that is manageable to me as opposed to saying I need to read 30 pages to cover the chapter. In addition, each mini lesson is 2 pages. The left page describes the material and the right page provides the examples. No longer do I have to hunt for the examples in the discussion. And the book is less than $100. This was a true bargain in the runaway prices of textbooks in colleges these days, especially in the STEM subjects.”
- Posted at an online bookseller

“I have worked for several training companies as a trainer, and I can categorically state that Murach Books are superior to any courseware that I have ever encountered. Your examples and code are more hands-on, and they work. You may quote me.”
- Robert Vaughn, PhD, Iowa

Unlike other publishers, we don’t fill dozens of pages in our books with end-of-chapter activities that may never be used. Instead, we provide everything you need for an effective course in a download from our instructor’s website. Then, you decide which of these materials you want to use. In short, our instructor’s materials provide a turnkey package for a powerful Java course.

For a detailed description of all the materials, please see the Instructor’s Summary PDF. But here’s a quick overview:

End-of-chapter exercises

  • The EOC exercises are carefully designed to let your students (1) practice what they’ve just learned and (2) apply what they’ve learned in new ways.
  • Our exercises start from partial applications, so your students can focus on new skills and not waste time on repetitive code that they’d never code from scratch in a work environment.
  • Students can download the solutions to the EOC exercises from our retail website. We’ve found that these solutions keep students from giving up when they get stuck on a problem and that the model code also helps them refine their future work. For testing your students' coding skills, we provide projects where the solutions are available only to instructors (see below).
  • These exercises allow your students to practice and learn more in less time.

Objectives

  • Our objectives describe the skills that the students should master, and this mastery can be measured by the test banks and projects that we provide. As a result, our objectives facilitate learning.

Test banks

  • To test comprehension, we provide test banks in multiple formats that can be imported to all modern LMSs.
  • Each test bank provides questions that are designed to test the skills described by the objectives for that chapter, and each test question is designed to test the skill described by one objective. This keeps the promise to the students that they will only be expected to have the skills that are described by the objectives.
  • In the test banks, we use only multiple-choice test questions because they have the highest validity. In other words, the students with the best knowledge and skills will get the best scores. In contrast, matching and true/false questions have low validity, so we don’t use them.

Projects

  • The best way to develop programming skills is to write, test, and debug applications from scratch. To that end, we provide a set of projects for each chapter. These projects can be used for both practice and tests.
  • To make the projects as useful as possible, we provide a range of difficulty levels. That way, you can assign projects at levels that are appropriate for the students in your class.
  • Some of these projects can be done in an hour or less, so you can use them as tests. This is the only sure way to test whether your students have the skills described by the objectives.

PowerPoint slides

  • In our books, the figures present all of the critical information, including screen shots, diagrams, tables, code examples, and applications. Then, we build our PowerPoint slides from the figures, which means that our slides let you review everything that’s presented in the book. This makes it easy to answer any questions that your students raise or review any skills that your students are having trouble with.
  • The slides for each chapter start with the chapter objectives. That helps your students stay focused on what they’ll learn and be tested on.

On this page, we’ll be posting answers to the questions that come up most often about this book. So if you have any questions that you haven’t found answered here at our site, please email us. Thanks!

There are no book corrections that we know of at this time. But if you find any, please email us, and we’ll post any corrections that affect the technical accuracy of the book here. Thank you!
