This JEP also finalizes this feature and incorporates enhancements in response to feedback from the previous four rounds of preview: JEP 433, Pattern Matching for switch (Fourth Preview), delivered in JDK 20 JEP 427, Pattern Matching for switch (Third Preview), delivered in JDK 19 JEP 420, Pattern Matching for switch (Second Preview), delivered in JDK 18 and JEP 406, Pattern Matching for switch (Preview), delivered in JDK 17. Similarly, JEP 441: Pattern Matching for switch, has been promoted from its JEP Draft 8300542 to Candidate status. The most significant change from JEP 432 removed support for record patterns appearing in the header of an enhanced for statement. Record patterns may be used in conjunction with type patterns to "enable a powerful, declarative, and composable form of data navigation and processing." Type patterns were recently extended for use in switch case labels via: JEP 420, Pattern Matching for switch (Second Preview), delivered in JDK 18, and JEP 406, Pattern Matching for switch (Preview), delivered in JDK 17.
This feature enhances the language with record patterns to deconstruct record values.
This JEP finalizes this feature and incorporates enhancements in response to feedback from the previous two rounds of preview: JEP 432, Record Patterns (Second Preview), delivered in JDK 20 and JEP 405, Record Patterns (Preview), delivered in JDK 19.
