Learn Java with Projects

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 – Park Operations System – the calm before the storm

While our park thrives with lively dinosaurs and excited visitors, our behind-the-scenes operations must run concurrently and seamlessly. The use of concurrency can ensure that tasks such as feeding dinosaurs, tracking dinosaur movements, and scheduling staff shifts are handled efficiently.

However, despite our best efforts, things start to go awry. A few dinosaurs become restless, security systems begin to glitch, and staff reports mysterious occurrences. Could this be the calm before the storm, and will we relive what happened in a famous competing park they made a movie about?

Update the following Park Operations System so that it concurrently safely handles different park operations. Use low-level threading, ExecutorService, atomic classes, synchronized blocks, and the Lock interface to manage concurrent access to shared resources. Prevent and handle race conditions, deadlocks, livelocks, and starvation...
