Java 9 Features (with Examples)

Java 9 was released on September 21, 2017 – three and a half years after Java 8. It was the last release in the old style: a bundle of 91 JDK Enhancement Proposals (JEPs) that was only released once the largest of them was finished – the module system. Half a year later, Java 10 started the six-month release cycle – and the releases became much smaller. Java 9 was not a long-term support release.
