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.

Contrasting method overriding and method overloading

These two terms are often confused but in this section, we will compare and contrast both. We will show that concerning method overloading, the method signature must be different; whereas concerning method overriding, the method signature must be the same. Recall that the method signature consists of the method name and the parameter types, including their order. The return type and the parameter identifiers are not part of the method signature. So, for example, take the method from Figure 9.5:

public static void doAction(Vehicle v){…}

The signature is doAction(Vehicle).

With this in mind, we will initially discuss method overloading.

Method overloading

Recall that the method signature consists of the method name and the parameter types. Method overloading is where you have the same method name but the parameters differ, either in type and/or order. This means that the method signatures are different even though...
