    • 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
        Converts the given object into a JavaVersion.
        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

        public static JavaVersion current()
        Returns the version of the current JVM.
        Returns:
        The version of the current JVM.
