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

We’ve learned so many fun new things in this chapter. It’s time to enlighten the users of the Mesozoic Eden software with some new features that have been built with our new skills:

  1. Manage the birthdays of the dinosaurs in our park. Add the birthday property to the Dinosaur class.
  2. The park operates on a strict schedule. Create a simple system to log events such as feeding times, cleaning, and emergency drills in the park using the Date API.
  3. In Mesozoic Eden, we have a very strong safety-first policy. Regular inspections help us maintain our high standards of safety. Create a program that calculates how many days are left until the park’s next safety inspection, based on the date of the last safety inspection. Safety inspections need to happen every 45 days.
  4. We have a newborn Theropod. The guests were asked to submit names for our youngest inhabitant of Mesozoic Eden. 10 names were picked. Create a list for these 10 names.
  5. We want...
