  - ### Method Detail

    - #### values

          public static JavaVersion[] values()

      Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

          for (JavaVersion c : JavaVersion.values())
              System.out.println(c);

      Returns:
        an array containing the constants of this enum type, in the order they are declared

    - #### valueOf

          public static JavaVersion valueOf​(String name)

      Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)
      Parameters:
        `name` - the name of the enum constant to be returned.
      Returns:
        the enum constant with the specified name
      Throws:
        `IllegalArgumentException` - if this enum type has no constant with the specified name
        `NullPointerException` - if the argument is null

    - #### toVersion

          public static JavaVersion toVersion​(Object value)
                                       throws IllegalArgumentException

      Parameters:
        `value` - An object whose toString() value is to be converted. May be null.
      Returns:
        The version, or null if the provided value is null.
      Throws:
        `IllegalArgumentException` - when the provided value cannot be converted.

    - #### current
