Before we explore what we can do with variables, let’s learn how to keep code organized in Java.
Whitespace is one or more characters (such as a space, tab, enter, or return) that do not produce a visible mark or text. Whitespace is often used to make code visually presentable.
Java will ignore whitespace in code, but it is important to know how to use whitespace to structure code well. If you use whitespace correctly, code will be easier for you and other programmers to read and understand.
