Overview of this book

Are you trying to start a career in programming, but haven't found the right way in? Do you have a great idea for an app, but don't know how to make it a reality? Or maybe you're just frustrated that in order to learn Android, you must know Java. If so, then this book is for you. This new and expanded second edition of Android Programming for Beginners will be your companion to create Android Pie applications from scratch. We will introduce you to all the fundamental concepts of programming in an Android context, from the basics of Java to working with the Android API. All examples use the up-to-date API classes, and are created from within Android Studio, the official Android development environment that helps supercharge your application development process. After this crash course, we'll dive deeper into Android programming and you'll learn how to create applications with a professional-standard UI through fragments and store your user's data with SQLite. In addition, you'll see how to make your apps multilingual, draw to the screen with a finger, and work with graphics, sound, and animations too. By the end of this book, you'll be ready to start building your own custom applications in Android and Java.

Chapter 7. Java Variables, Operators, and Expressions

In this chapter and the next, we are going to learn and practice the core fundamentals of Java data and manipulating that data. In this chapter, we will focus on the creation and understanding of the data itself, and in the next, we will see how to manipulate and respond it.

We will also quickly recap what we learned in the earlier chapters about Java, and then dive into learning how to write our very own Java code. The principles we are about to learn are not limited to Java, but are also applicable to other programming languages as well.

By the end of the chapter, you will be comfortable writing Java code that creates and uses data within Android. This chapter takes you through the following:

  • Java syntax and jargon
  • Variables
  • Operators
  • Expressions

Let's learn some Java.
