Chapter 13. Arrays

If you have done any scientific or engineering programming you are familiar with using arrays. In Java, as in every other programming language, arrays are used for storing data. If you solve a system of equations or create a computational grid you will be using arrays. Since Java is a C-based language, there are some similarities between Java and C arrays. Java array indices start at 0. An element of a Java array can be accessed using the element index surrounded by brackets, [].

There are some notable differences between Java and C arrays. Java arrays are objects. Memory for an array is allocated on the heap using the new keyword. Arrays implicitly extend from the Object class and can use Object class methods. Unlike other languages, ...

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.
