    Question Convert List<Set<String>> to string array

    Hi all,

    I am a beginner in java and would like to know how to convert List<Set<String>> to an array, so that the output would be without brackets and commas. I have the following part of code:

    List<Set<String>> ls = new ArrayList();
    for (int i = 0; i < ls.size(); i++) {



    [x, y, z]

    [c, e]

    I tried with toArray(), but I'm getting an ArrayStoringException error.
    Can anyone give some hints?

    the output would be without brackets and commas.
    How are you printing it? If you write your own printing code you will have complete control over what is output.
    If you don't understand my answer, don't ignore it, ask a question.
