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.

Project – Dino tracker

Safety always comes first. That’s why keeping track of all our dinosaur residents is of utmost importance. The park managers need to have an easy-to-use system for managing information about their slightly exotic pets.

For this project, you’ll be creating a Dino tracker. This is a simple tracking system that maintains records of each dinosaur’s name, age, species, and enclosure number. This will be done using fixed arrays – four arrays in total, one for each attribute.

Assume you have room for 10 dinosaurs in your park for now, so each array should have a length of 10. Each dinosaur will correspond to an index in the array. For example, if the dinosaur “Rex” is in the first position of the name array, his age, species, and enclosure number will also be in the first position of their respective arrays.

You’re going to print information about all the dinosaurs and print their average age and weight...
