Java Generics: Past, Present and Future
Показать описание
Generics are one of the most complex features of Java. They are often poorly understood and lead to confusing errors. Unfortunately, it won’t get easier. Java 10, release planned for 2018, extends Generics. It’s now time to understand generics or risk being left behind.
We start by stepping back into the halcyon days of 2004 and explain why generics were introduced in the first place back. We also explain why Java’s implementation is unique compared to similar features in other programming languages.
Then we travel to the present to explaining how to make effective use of Generics. We then explore various entertaining code examples and puzzlers of how Generics are used today.
Finally, this talk sheds light on the planned changes in Java 10 with practical code examples and related ideas from other programming languages. If you ever wanted to understand the buzz around higher kinded types or declaration site variance now is your chance!

Richard Warburton
Richard Warburton is a software developer who loves solving complex problems, but actively challenges how much of software development is dealing with day-to-day trivialities. Having obtained a PhD in the area of compiler optimizations and static analysis, he has been applying his abilities in industry. Initially on bytecode analysis software, and more recently on Java performance tuning tools. He actively involves himself in the London Java Community, and its Java Community Process Committee. He has been helping with the push to improve and complete the JSR 310 API and the expand community engagement with JSR 335.

Raoul started his PhD in Computer Science at the University of Cambridge at the age of 20. He is a frequent speaker at developer conferences. He holds a MEng in Computer Science from Imperial College London and graduated with first class honours having won several prizes for technical innovation. He has worked on several startup projects as well as worked for large companies such as eBay, Oracle, and Goldman Sachs.
