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.

Generics and Collections

Organizing data is another important software development topic. Java hands us collections to deal with various data structures. It also gives us generics to achieve type safety and avoid duplicate code in our applications. We cannot say we’re masters of Java without understanding how to use collections and generics.

That’s why we devoted this chapter to the Java collections framework. In this chapter, we’ll cover the following topics:

  • The collections framework and its interfaces – List, Set, Map, and Queue
  • Several implementations of each collection type and their basic operations
  • Sorting collections using natural ordering and the Comparable and Comparator interfaces
  • Working with generics
  • Basic hashing concepts and their relevance

By the end of this chapter, you will have a solid understanding of the Java collections framework and generics, and you’ll be ready to manage data and use collections...
