Learn Java with Projects

Overview of this book

Learn Java with Projects stands out in the world of Java guides; while some books skim the surface and others get lost in too much detail, this one finds a nice middle ground. You’ll begin by exploring the fundamentals of Java, from its primitive data types through to loops and arrays. Next, you’ll move on to object-oriented programming (OOP), where you’ll get to grips with key topics such as classes, objects, encapsulation, inheritance, polymorphism, interfaces, and more. The chapters are designed in a way that focuses on topics that really matter in real-life work situations. No extra fluff here, so that you get more time to spend on the basics and form a solid foundation. As you make progress, you’ll learn advanced topics including generics, collections, lambda expressions, streams and concurrency. This book doesn't just talk about theory—it shows you how things work with little projects, which eventually add up to one big project that brings it all together. By the end of this Java book, you’ll have sound practical knowledge of Java and a helpful guide to walk you through the important parts of Java.

To get the most out of this book

While much of the code will work with earlier Java versions, we would recommend installing or upgrading to Java 21 to avoid version-related compiler errors.

If you currently have nothing on your system, the following setup would be great:

  • JDK 21 or later (Oracle’s JDK or OpenJDK)
  • IntelliJ IDEA (community edition is good enough) or Eclipse or Netbeans

Software/hardware covered in the book

Operating system requirements

Java 21+

Windows, macOS, or Linux

See Chapter 1 for instructions on how to get both Java and an IDE installed on various operating systems.

If you are using the digital version of this book, we advise you to type the code yourself or access the code from the book’s GitHub repository (a link is available in the next section). Doing so will help you avoid any potential errors related to the copying and pasting of code.
