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.

Getting to know collections

Collections are worth getting to know. Collections are a much more elegant way of dealing with multiple values in one variable than arrays. A common example of a collection would be a list.

Writing any proper Java application without collections would be very complicated. You’d probably start by creating some classes that will act like Java’s built-in collections. They play a vital role in software development as they provide a means to manage and organize data.

There are many reasons why we need them, but let’s just list (collection pun) a few:

  • Managing large amounts of data: As applications grow in complexity, they often need to deal with large amounts of data. Collections help store and manage these datasets. They also come with helpful methods that make it easier to perform typical operations on data, such as searching and filtering.
  • Storing and manipulating various data structures: Different data structures have...
