Java Collections Power Techniques

The Java Collections framework is a cornerstone of Java development. It's been a part of J2SE for six years now. Every Java developer knows it—how to create Lists, Maps, and Sets, how to put things into them and take things out, and how to iterate over the contents. But there's a lot more to the collections framework than that – and very few programmers really know how to exploit the power that's just under the surface.

The basics of the collections classes are so simple that many developers haven't even thought to look for the additional power that's there. And it's not just built-in capabilities, either. The design of the collections framework makes possible several powerful techniques and patterns that can magnify your productivity, as well as helping you build systems that are efficient and scalable.

It may seem strange to give a talk on a framework that every Java programmer already knows. But in every project I've worked on for the past six years, I've seen a lot of code that uses the collections poorly. More often than not, that code was written by skilled programmers with significant Java experience. In this talk, you'll learn how to use the collections well, exploiting their full power—the little-known capabilities, the extensibility features, and powerful patterns such as wrappers, adapters, and decorators. We'll also cover some new features that slipped into Java 1.5, plus a few especially useful third-party collection implementations.
