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.

Working with Arrays

Arrays are an essential data structure that you can use to store multiple values in one variable. Mastering arrays will not only make your code more organized and efficient but also open the door to more advanced programming techniques. Once you add arrays to the mix, you can level up the data structures of your applications.

In this chapter, we’ll explore arrays and equip you with the skills needed to effectively work with this fundamental data structure. You’ll learn how to create, manipulate, and iterate over arrays to solve a wide range of programming challenges.

Here’s an overview of what we’ll cover in this chapter:

  • What arrays are and how to use them
  • Declaring and initializing arrays
  • Accessing array elements
  • Getting the length of an array and understanding the bounds
  • Different ways to loop through arrays and process their elements
  • Working with multidimensional arrays
  • Performing common operations...
