替换阵列上的括号

Question

I have an array like this: ["one", two"]

If I make array.toString().replace("[", "").replace("]", "").trim(); , I will have: "one, two"

What I really want is "one", "two"

How can I do this?

EDIT:

This is a simple program to explain my question:

 ArrayList<String> array = new ArrayList<>();

    array.add("one");
    array.add("two");

    String stringArray = array.toString().replace("[", "").replace("]", "");

    Gson gson = new Gson();
    String json = gson.toJson(stringArray);
    System.out.println(json);

Answer 1

You can try with

array.stream().map(s->"\""+s+"\"").collect(Collectors.joining(", "));

which will first surround each strings with quotes, then join them using ,

For Java 7

String delimiter = ", ";
StringBuilder sb = new StringBuilder();

if (!array.isEmpty()) {
    sb.append('"').append(array.get(0)).append('"');
}
for (int i = 1; i < array.size(); i++) {
    sb.append(delimiter).append('"').append(array.get(i)).append('"');
}

String result = sb.toString();

Answer 2

Well, just replace comma's with some extra " 's

array.toString().replace("[", "").replace("]", "").trim().replace(", ", "\", \"")

(Not tested, but you get the idea)
