Chapter 1. What’s New?

Note

In this chapter:

Even with nearly 200 pages before you, it’s going to be awfully tough to cover all of Tiger’s new features. Whether it’s called Java 1.5, 2.0, Java 5, or something altogether different, this version of Java is an entirely new beast, and has tons of meat to offer.

Rather than waste time on introductory text, this chapter jumps right into some of the “one-off” features that are new for Tiger, and that don’t fit into any of the larger chapters. These will get you used to the developer’s notebook format if it’s new for you, and introduce some cool tools along the way. Then Chapter 2 gets downright serious, as generics are introduced, and from there to the last page, it’s a race to cram everything in.

Working with Arrays

Tiger has a pretty major overhaul of its collection classes, most of which have to do with generic types and support for the new for/in loop. Without getting into those details yet, you can get some immediate bang for your buck by checking out the java.util.Arrays class, which is chock-full of static utility methods (many of which are new to Tiger).

How do I do that?

The java.util.Arrays class is a set of static methods that all are useful for working with arrays. Most of these methods are particularly helpful if you have an array of numeric primitives, which is ...

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.
