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

Now that we can iterate, it’s time to do some similar tasks to the chapters before but iterate for multiple values!

Be creative on how to implement these ones and add context where you need it. As always, there’s not one right answer:

  1. All of our dinosaurs are unique. Okay, we cloned their DNA, but still. Let’s say they have unique personalities. That’s why the IDs of all our dinosaurs are unique too: they are called dino1, dino2, dino3, and so on. Write a for loop that prints out the IDs of the first 100 dinosaurs in the park.
  2. Some of our dinosaurs have large appetites! Write a do-while loop that continues to feed a dinosaur until it is no longer hungry.
  3. We all love the thrill of waiting for the park to open. Use a while loop to print out a countdown to the park’s opening time.
  4. For planning purposes, it’s essential to know the total weight of all dinosaurs in a specific enclosure. Write a for loop that calculates...
