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.
