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

All is going great in our lovely dinosaur park. However, we do need to do some administrative tasks:

  1. We need to keep track of the dinosaurs in the park. Declare variables to represent the breed, height, length, and weight of one dinosaur in the main method. Give the variables a value and print them.
  2. Now, we want to do something similar to the program of exercise 1 and print the dinosaur’s age, name, and whether it’s a carnivore or not. This needs to happen in the main method. Give the variables a value and print them.
  3. Our park is doing great! But it gets a bit too busy at times. The fire department advised us to introduce a maximum number of visitors that are allowed at any given time. Declare a variable to represent the maximum number of visitors allowed in the park per day. You can choose a reasonable value for the variable. Then, print it in the sentence: “There’s a maximum of [x] people allowed in Mesozoic Eden.”
