Append quotes to strings in an array and make it comma separated string in Java

Java 8 has Collectors.joining() and its overloads. It also has String.join.
Using a Stream and a Collector

Function<String,String> addQuotes = s -> "\"" + s + "\"";

String result =
  .collect(Collectors.joining(", "));
String result = .map(s -> "\"" + s + "\"") .collect(Collectors.joining(", "));
String result = listOfString.isEmpty() ? "" : "\"" + String.join("\", \"", listOfStrings) + "\"";

Happy Coding!
