| gptkbp:description |
Enhances the instanceof operator to allow pattern matching.
Enhances the Java programming language with record patterns. This JEP proposes to remove the Java EE and CORBA modules from the JDK. Provides a new class type for modeling immutable data. Provides a mechanism for context-specific deserialization. Enhances the String conversion mechanism in Java. This JEP proposes to return unused memory to the operating system promptly. Introduces a new string literal syntax that allows for context-sensitive string literals. |
