How to add double quotes automatically, converting a list of strings as comma-separated values?

We can perform it in two steps with StringUtils only,

List s = new ArrayList<>();
s.add("ten");
s.add("twenty");
s.add("thirty");

String step1 = StringUtils.join(s, "\", \"");// Join with ", "
String step2 = StringUtils.wrap(step1, "\"");// Wrap step1 with "

System.out.println(step2);

Output,

"ten", "twenty", "thirty"
