Overview of this book

Learn Java with Projects bridges the gap between introductory Java guides and verbose, theoretical references. This book is crafted to build a strong foundation in Java programming, starting from the Java environment itself. It goes far beyond a superficial review of the topics; it demonstrates, with practical examples, why these fundamentals are crucial for developing a deep understanding of the language. You'll not only learn about classes and objects but also see how these concepts are used in practical scenarios, enhancing your ability to write clean, efficient code. The engaging projects throughout the book provide real-world applications of complex topics, ensuring you can connect theoretical knowledge with practical skills. What makes this book stand out is the expertise of its authors. Seán, a seasoned university lecturer with over 20 years of experience, brings academic rigor and real-world insights, thanks to his work with a prestigious software company. Maaike, a passionate software developer and award-winning trainer, brings hands-on experience and a love for teaching. By the end of this book, you'll not only understand Java's core concepts and the critical advanced ones, but also gain practical experience through projects that mimic real-life challenges.

Java Core API

In this chapter, we will delve more deeply into popular classes and interfaces from the Java API. We will start with the Scanner class, which is commonly used for scanning and parsing text from sources such as the keyboard (the user). We will then examine the very popular String and StringBuilder classes. We will discuss their differences, which will require contrasting mutable and immutable types. We will also show you how to design immutable types and look at the List interface and its popular implementation class, ArrayList. Lastly, we will examine the Date API, which was overhauled in Java 8.

For further details on the types covered in this chapter, please refer to the Java Docs API: https://docs.oracle.com/en/java/javase/21/docs/api/index.html.

This chapter covers the following main topics:

  • Understanding the Scanner class
  • Comparing String with StringBuilder
  • Designing an immutable type
  • Examining List and ArrayList
  • Exploring the Date API...
