JDK 23: The new features in Java 23
Java Development Kit (JDK) 23, the next planned version of standard Java, is off and running, with two features now scheduled for the release.
Due September 19, JDK 23 has just added a second preview of a class-file API, providing a standard API for parsing, generating, and transforming Java class files. This feature was previously previewed in JDK 22, which was released on March 19. Previously slotted for JDK 23 was a preview of primitive types in patterns, instanceof, and switch.
