public enum JavaFeature
extends Enum<JavaFeature>

An internal enumeration of all Java language features that were introduced as standard feature or preview feature from Java 15. The idea is to have one location where the applicability of a feature, such as version supported in, whether or not a preview, what are the restricted keywords introduced by a feature etc. This is expected to be updated every time there's a new Java version and the change is expected to be one of the following kinds:

• The preview feature continues to be a preview in the next version
• The preview feature is upgraded to a standard feature
• The preview feature is removed
