Picnic & NLJUG Java 14 Masterclass

Picnic & NLJUG

Code in this repository is the starting point for all live-coding demos in the Java 14 Masterclass. If you want, you can clone this repository and follow along with the demos, or try them yourself at a later time.

The master branch does not use any Java 14 features as-is, that's what we'll be doing during the masterclass! The resulting code can be found in the java14 branch of this repository.

Pre-requisites

  • Download & unpack Java 14 from http://jdk.java.net/14/
  • Ensure the JAVA_HOME variable points to the JDK installation directory
  • If you want to use javac from the command-line, ensure the JDK's bin folder is added to your PATH
  • Ensure Maven 3.x is installed
  • Optional: install IntelliJ 2020.1 (Community Edition is fine), or another IDE with Java 14 language support

Running the demo code

Within every sub-directory, you can run mvn compile exec:java to compile & execute the main class for that sub-module.

If you're using an IDE, make sure it is configured to point to the Java 14 JDK, and that preview features are enabled at the Java 14 language level. For IntelliJ, here's a description on how to do so (under 'IntelliJ IDEA configuration').
