Показать описание

JEP 427 proposes two changes to pattern matching in switch: 1. Guarded patterns, which belonged to patterns, are replaced with when clauses, which belong to the case. 2. null needs to be handled by a specific case null.

My vote on dealing with null in switch is: explicit case clause only. Exception to occur when null is fed to any switch not having an explicit null case. No use of catch-all case for this purpose. It adds nothing and its obviously confusing. "When" is fine, a reasonably powerful soln with maximal ease of understanding whilst limiting unnecessary complexity.

Can we move Optional to java.lang and deprecate null for removal please?
