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.

Working with threads

Let’s finally get to explaining threads. Threads are sequences of executed instructions, representing the most fundamental units of execution. Each thread follows a certain path through the code. The threads perform specific tasks within processes. A process is typically composed of multiple threads.

To give you an example, the programs we’ve created so far had one user-created thread (and the user in this case is the developer). The thread went through the lines of code in a certain order; for example, when a method was called, the thread would execute that method before continuing with the code that was directly on the next line after the method call. This is the path of execution of the thread.

When multiple threads are running, multiple paths of execution are being walked through your code, and that’s why multiple things are happening at the same time.

In order to make this possible, we’ll need duplicates of certain Java...
