Functional programming is a programming style that treats computation as the evaluation of mathematical functions and avoids changing-state and mutable data. It is a declarative programming paradigm in that programming is done with expressions or declarations instead of statements. For years, the conventional wisdom around attempting pure functional programming in …
The purpose of this talk is to illustratie why and how implementing laziness in Java with practical examples delivered with both slides and live coding sessions. Like all imperative programming languages Java is, with some minor but notable exceptions, an eagerly evaluated programming language. Nevertheless the introduction of lambdas in …
This video is a Q&A session with Brian Goetz who is the Java Language Architect at Oracle. He was specification lead for JSR 335 (Lambda Expressions for the Java Language.) He is the author of the best-selling book “Java Concurrency in Practice” and is a frequent presenter at major industry …
Lambda expressions and the streams API add a more functional style of programming to Java; something developers have not really had in the past. The session starts with a short summary of the key features of both Lambda expressions and streams before moving on to some real world examples of …
As the software development industry matures there is an increasing demand for high-throughput, low-latency systems heavily utilizing event-driven programming and asynchronous processing. This trend is rapidly converging on the somewhat well established but so-far not well understood term “Reactive”.
Java 8 was launched in March 2014 with great fanfare. The new lambda syntax allows us to have a more succinct coding style and get rid of a lot of boilerplate code. However, there is also confusion. Even the “State of the Lambdas” paper starts by comparing lambdas to ActionListener.
