Welcome to the first part of my Java 8 Concurrency tutorial. This guide teaches you concurrent programming in Java 8 with easily understood code examples. It’s the first part out of a series of tutorials covering the Java Concurrency API. In the next 15 min you learn how to execute code in parallel via threads, tasks and executor services. Part 1: Threads and Executors Part 2: Synchronization and

This article demonstrates how to combine React.js with Java and Spring Boot in order to pre-render fully-fledged MVC-frontends on the JVM server without even thinking about Node.js. Wait. Isomorphic Webapps? What the heck is that? Isomorphic JavaScript apps are JavaScript applications that can run both client-side and server-side.The backend and frontend share the same code. Traditionally webapps

This example-driven tutorial gives an in-depth overview about Java 8 streams. When I first read about the Stream API, I was confused about the name since it sounds similar to InputStream and OutputStream from Java I/O. But Java 8 streams are a completely different thing. Streams are Monads, thus playing a big part in bringing functional programming to Java: In functional programming, a monad is a

Learn all about the Nashorn Javascript Engine with easily understood code examples. The Nashorn Javascript Engine is part of Java SE 8 and competes with other standalone engines like Google V8 (the engine that powers Google Chrome and Node.js). Nashorn extends Javas capabilities by running dynamic javascript code natively on the JVM. In the next ~15 minutes you learn how to evaluate javascript on
