Chapter 8. Variables

In Chapter 7 we discussed how classes could define fields as members of the class. You may be more familiar with the term variable. A variable is a storage location. A variable always has a type associated with it. A variable of primitive type holds the value of a primitive type. A reference type variable holds either a null reference or a reference to an object of the same type as the variable. There are seven kinds of Java variables. Fields, depending on how they are declared, represent two of them. Fields that are declared as static are called class variables. Fields not declared as static are called instance variables. The other Java variable types are array components, method parameters, constructor parameters, exception ...

Julian F.

Head of Cybersecurity

I wanted to learn C and C++, but it didn't click for me until I picked up an O'Reilly book. When I went on the O’Reilly platform, I was astonished to find all the books there, plus live events and sandboxes so you could play around with the technology.

Addison B.

Field Engineer

I’ve been on the O’Reilly platform for more than eight years. I use a couple of learning platforms, but I'm on O'Reilly more than anybody else. When you're there, you start learning. I'm never disappointed.

Amir M.

Data Platform Tech Lead

I'm always learning. So when I got on to O'Reilly, I was like a kid in a candy store. There are playlists. There are answers. There's on-demand training. It's worth its weight in gold, in terms of what it allows me to do.
