JEP 455 proposes enhancing pattern matching in Java by allowing primitive type patterns in all contexts and extending instanceof and switch to work with all primitive types.
The proposal simplifies code by allowing developers to directly test and convert between different primitive types without verbose syntax. It improves code readability and reduces errors related to lossy conversions.
The enhancement also addresses limitations related to record patterns and their interaction with primitive types, providing better support and potential simplification of code. [ more ]
