How to create a String with String.format by taking parameters from a list

aristas :

I want to create a String with String.format like this String.format("Q1={}, Q2={}, Q3={}, Q4={}" list) from the values of a list that contains Integers.

private String createString(Player player){

List<Integer> answers= new ArrayList<>();
    answers.add(player.getQuestion1());
    answers.add(player.getQuestion2());
    answers.add(player.getQuestion3());
    answers.add(player.getQuestion4());
    answers.add(player.getQuestion5());
    answers.add(player.getQuestion6());
    answers.add(player.getQuestion7());
    answers.add(player.getQuestion8());
    answers.add(player.getQuestion9());
    answers.add(player.getQuestion10());
    return String.format("Q1={}, Q2={}, Q3={}, Q4={}, Q5={}, Q6={}, Q7={}, Q8={}, Q9={}, Q10={}", answers.stream().map(a -> a.toString());

}

Naman :

Something like the following using Collectors.joining with mapping as required witht index and answer :

return IntStream.range(0, answers.size())
            .mapToObj(idx -> String.format("Q%s = %s", idx + 1, answers.get(idx)))
            .collect(Collectors.joining(", "))
