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.

Dealing with Exceptions

Error handling is another fundamental concept of software development. An error happens when the program can’t or doesn’t know how to react to a certain situation. Error handling allows you to respond to unexpected events in your program gracefully. Without error handling, the application would crash and stop running when the error occurred.

In Java, we have different types of errors. The type of error that we deal with most is called an exception. In Java terms that we’ll learn later, an Exception is not an Error. This is related to the class hierarchy. However, sticking to daily linguistics it is not weird to think of an exception as some sort of error.

But, instead of talking about errors, we usually talk about exceptions. Errors occur as well, but errors are typically situations your application will not recover from. Your application should be capable of recovering from an exception.

Exception handling in Java allows you to...
