The world of Java is constantly changing. While getting from Java 1 to Java 9 took 22 years,  now a new Java version is released every 6 months, and a new long-term support version every few years. Java 8 brought us lambdas, and the streaming functional programming revolution. Java 9 added modules and a built-in mature API for Reactive programming. Java 10 added local type deduction with vars, and the list goes on.

This seminar explores the new features included in 9 – 16 short & long-term releases and introduces the latest APIs, environmental updates, new utilities and deprecated ones.
