From Agile Developer
Dr. Venkat Subramaniam is an award-winning author, founder of Agile Developer, Inc., and an instructional professor at the University of Houston.
He has trained and mentored thousands of software developers in the US, Canada, Europe, and Asia, and is a regularly-invited speaker at several international conferences. Venkat helps his clients effectively apply and succeed with agile practices on their software projects.
Venkat is a (co)author of multiple books, including the 2007 Jolt Productivity award winning book Practices of an Agile Developer. His latest book is Functional Programming in Java: Harnessing the Power of Java 8 Lambda Expressions. You can reach him by email at firstname.lastname@example.org or on twitter at @venkat_s.
Efficiency is achieved not just by running things faster, but by avoiding things that shouldn't be done in the first place. Lazy evaluations are a core feature of many functional programming languages. Your code can benefit from lazy evaluations with lambda expressions and, more so, with the power of Streams. In this presentation, we'll start with a discussion of lazy evaluations, with short examples from Haskell and Scala. Then we'll dive into Java to see how we can achieve similar benefits using lambdas and the Stream API.
Kotlin is that dark horse of JVM languages. It has gained prominence in the recent times for various good reasons. But, what does Kotlin really mean to Java programmers? In this presentation we will explore the language, learn about its key strengths and capabilities, take a peek under the hood to what it’s capabilities mean on the Java eco system, and how and where we can benefit from it.
Java 8 makes it relatively easy to program with parallel streams and to implement asynchronous tasks using CompletableFuture. When someone says it’s easy, cautious programmers ask “What’s the catch?” Well, of course, that’s one of the major topic we’ll address in this deep dive session. We will start with a fast introduction to parallel and asynchronous programming with Java 8 and quickly delve into the gotchas, when to use these facilities, when to avoid them, and how and where to put them to good use.
