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

With interfaces and abstract classes, we can improve our application structure even further! Take a look at the following exercises to test your knowledge:

  1. Dinosaurs, no matter the exact species, have common behaviors such as eating and moving. Define an interface that encapsulates these behaviors, come up with a logical name for it, and implement it in the Dinosaur class.
  2. Our park uses different types of vehicles for different purposes. Design an abstract class called Vehicle and derive concrete classes such as Jeep and Helicopter from it.
  3. Modify the Vehicle class so that it includes an abstract method called travel() that provides different implementations in its subclasses.
  4. Make our Dinosaur class sortable by implementing the Comparable interface to compare dinosaurs based on their age.
  5. Similarly, our employees also have common behaviors. Define a Worker interface with methods that represent these behaviors and implement it in the Employee class...
