You can just use Weekday.values[2] and get the same thing. If you need range safety, create a method that checks the ordinal and then indexes into the values array. No need to build a map. public static valueOf(int ordinal) { if (ordinal = values.length) return null; return values[ordinal]; } Why do you need a method?

public static valueOf(int ordinal) {
if (ordinal = values.length) return null;
return values[ordinal];
