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

Arrays are incredibly useful for storing and managing similar types of data, such as a list of dinosaur names, dinosaur weights, and visitors’ favorite snacks. Arrays are helpful and they enable us to manage more complex data in Mesozoic Eden. Try out the following:

  1. The unique appeal of our park lies in the diversity of our dinosaur species. (And also in that we have dinosaurs at all.) Create an array that holds the names of all the dinosaur species in the park. This list will help us in inventory management.
  2. Every visitor has their favorite dinosaur, and for many, it’s the heaviest one. Write a program that finds this star’s weight in an array of dinosaur weights. This information can then be highlighted in our park tours and educational programs.
  3. Dinosaurs come in all sizes, and the smallest ones hold a special place in the hearts of children. Write a program that finds this smallest dinosaur in an array of dinosaur weights.
  4. Running...
