Learn Java with Projects

Overview of this book

Learn Java with Projects stands out in the world of Java guides; while some books skim the surface and others get lost in too much detail, this one finds a nice middle ground. You’ll begin by exploring the fundamentals of Java, from its primitive data types through to loops and arrays. Next, you’ll move on to object-oriented programming (OOP), where you’ll get to grips with key topics such as classes, objects, encapsulation, inheritance, polymorphism, interfaces, and more. The chapters are designed in a way that focuses on topics that really matter in real-life work situations. No extra fluff here, so that you get more time to spend on the basics and form a solid foundation. As you make progress, you’ll learn advanced topics including generics, collections, lambda expressions, streams and concurrency. This book doesn't just talk about theory—it shows you how things work with little projects, which eventually add up to one big project that brings it all together. By the end of this Java book, you’ll have sound practical knowledge of Java and a helpful guide to walk you through the important parts of Java.

Exercises

Our park is full of diversity, not just in the species of dinosaurs but also in the roles of our employees. To model this diversity, we will be incorporating the concept of inheritance into our applications:

  1. Not all dinosaurs are the same. Some are small, others big. Some are herbivores, others carnivores. Create at least three subclasses for different types of dinosaurs that inherit from the base Dinosaur class.

    If you need inspiration, you can create a FlyingDinosaur subclass and an AquaticDinosaur subclass from the Dinosaur class, each with its unique properties. (This is not the most optimal way to model this, but don’t worry about that now.)

  2. Just like our dinosaurs, our employees also have diverse roles. Some are park managers, while others are security officers or veterinarians. Create subclasses for these employee roles that inherit from the Employee base class. Come up with at least three subclasses.
  3. Inheritance doesn’t just stop at properties...
