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 meal planner

Dinosaurs are not easy animals to keep. This is very advanced pet ownership. The right nutrition is difficult to manage, but it’s vital to their health and well-being. Therefore, you are asked to create a system that can manage the feeding schedule of our various dinosaur residents.

The project’s primary goal is to create a program that calculates the meal portions and feeding times for each dinosaur. Since we haven’t covered arrays yet, we’ll focus on a single dinosaur for now.

Here’s how we can do it:

  1. Start by declaring a variable to hold the current time; let’s say it’s an integer and it goes from 0 (midnight) to 23 (last hour of the day).
  2. Define variables for each dinosaur species with different feeding times. For example, T-Rex could eat at 8 (morning), 14 (afternoon), and 20 (evening), while the Brachiosaurus could eat at 7 (morning), 11 (mid-morning), 15 (afternoon), and 19...
