OpenJDK proposals would improve Java pattern matching
Java programming is set to be enhanced with record patterns and array patterns, and pattern matching for switch expressions and statements, although the arrival time of these capabilities remains undetermined.
In an online presentation on March 23, Gavin Bierman, consulting member of the technical staff at Oracle, cited these features as the focus of two JDK (Java Development Kit) enhancement proposals eyed for an upcoming, as-yet-undetermined release of Java, which would include them in a preview stage. The hope is that they would appear in the JDK 17 release planned for September.
