still very new to Java, my apologies if this has appeared before.

Basically here is the original code

public static MarketType[] convert(final String[] values) {
        return ofNullable(values).map(v -> Stream.of(values))
                .orElse(Stream.empty())
                .map(v -> getMarketType(v))
                .toArray(MarketType[]::new);
}

Since other functions changed, I really need the return type to be List<MarketType> instead of MarketType[], but is there any way that can achieve this with the minimal amount of modification for the original code? I have been trying to put different things in the toArray function but nothing really worked.

Any help appreciated!
