Learn Java with Projects

5 (3)
By: Dr. Seán Kennedy, Maaike van Putten

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 – agile dinosaur care system

Our park is growing, and so are the tasks that need to be accomplished. Lambda expressions can simplify our code and improve the efficiency of operations. Let’s integrate them into our system!

Incorporate lambda expressions into your “dinosaur care system” for sorting, filtering, and performing actions on collections of dinosaurs. Furthermore, design a notification system using method references to alert park staff about various events, enhancing communication and responsiveness within our park.

Here are the steps. We assume certain methods exist. You’ll have to create those methods according to your Dinosaur class’s design:

  1. Set up your project: If you haven’t already done so in the previous chapter, create a new Java project in your IDE. Make sure you have a Dinosaur class defined with properties such as name, species, healthStatus, and so on. You’ll also want to have a DinosaurCareSystem...
