Java 17 - What's new?

Oracle announced the release of Java 17 on September 14, 2021 (ref: https://www.oracle.com/news/announcement/oracle-releases-java-17-2021-09-14/).

If you work for a company that chooses to adopt Long Term Support (LTS) releases, you probably either use Java 8 or Java 11 (ref: https://www.oracle.com/java/technologies/java-se-support-roadmap.html)

In this meetup, I'll walk through some language features that were introduced between Java 11 and Java 17 including:

• Record classes
• Sealed classes
• Text blocks
• Pattern matching based on instanceof
• Switch Expressions

Additionally, these are some great resources to review ahead of the meetup:
