Java Language Specification
Java SE 14 Edition

The Java Language Specification, Java SE 14 Edition, was the official, authoritative specification of the Java programming language. It was published in February 2020 and followed the Java SE 13 Edition of the JLS.

It specifies the Java programming language as implemented in Java SE 14.

This Java SE 14 Edition goes beyond the Java SE 13 Edition of the JLS by specifying the following feature:

  • switch-expressions
  • pattern matching for instanceof (but only as a preview feature)
  • records (but only as a preview feature)
  • text blocks (but only as a preview feature)

This language change was introduced in Java SE 14 in 2020.
