Answer 1

Although it is late, just case if someone else comes to this thread... If you are using Java 8, you can use streaming and Collectors interfaces like the following:

List cloudChipList = new ArrayList();
    cloudChipList.add("Action");
    cloudChipList.add("Comedy");
    cloudChipList.add("Family");

    String result = cloudChipList.stream().collect(Collectors.joining(" , ", "Genre: ", "\n"));
    System.out.println(result);

Here Collectors.joining adds delimiter, prefix and suffix to the result, but it has an option with only the delimter, too.
