How to zip two Java Lists

by

Here’s Java-8 solution using the Pair class (like in @ZhekaKozlov answer):

public static <A, B> List<Pair<A, B>> zipJava8(List<A> as, List<B> bs) {
    return IntStream.range(0, Math.min(as.size(), bs.size()))
            .mapToObj(i -> new Pair<>(as.get(i), bs.get(i)))
            .collect(Collectors.toList());
}

In Java 9 onwards you can use Map.entry():

    public static <A, B> List<Map.Entry<A, B>> zipJava8(List<A> as, List<B> bs) {
        return IntStream.range(0, Math.min(as.size(), bs.size()))
                .mapToObj(i -> Map.entry(as.get(i), bs.get(i)))
                .collect(Collectors.toList());
    }
