Where is the documentation for the values() method of Enum?

by

You can’t see this method in javadoc because it’s added by the compiler.

Documented in three places :

The compiler automatically adds some special methods when it creates
an enum. For example, they have a static values method that returns an
array containing all of the values of the enum in the order they are
declared. This method is commonly used in combination with the
for-each construct to iterate over the values of an enum type.

  • Enum.valueOf class
    (The special implicit values method is mentioned in description of valueOf method)

All the constants of an enum type can be obtained by calling the implicit public static T[] values() method of that type.

The values function simply list all values of the enumeration.
