| gptkbp:description |
Enhances the Java programming language with pattern matching for the instanceof operator.
Provides an API to allow Java programs to safely and efficiently access foreign memory. This JEP proposes the removal of the Java EE and CORBA modules from the JDK. Enhances Class Data Sharing (CDS) to allow the sharing of class metadata across different Java applications. Introduces a new rendering pipeline for mac OS. Allows the use of local-variable syntax for lambda parameters. Enhances the switch statement to allow it to be used as an expression. Provides a mechanism for streaming events from the Java Flight Recorder. Introduces sealed interfaces to restrict which classes can implement them. This JEP proposes to enhance the Java programming language with pattern matching for the instanceof operator. |
