Google Gson - adding arrays to a List

I want to make sure if it's good. Maybe there is another better solution.

List list = new ArrayList();
    for (int i = 0; i < 3; i++) {
        String[] arr = { String.valueOf(i) };
        list.add(arr);
    }

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

Expected output:

[
[
"0"
],
[
"1"
],
[
"2"
]
]

If you are able to use Java 8 you can use streams:

List list = IntStream.range(0, 3)
    .mapToObj(i -> new String[] { String.valueOf(i) })
    .collect(Collectors.toList());

Let's break it down:

• IntStream.range(0, 3) gives you the values 0, 1 and 2

• .mapToObj(i -> new String[] { String.valueOf(i) }) converts them to a string and puts them into a String[]

• .collect(Collectors.toList()) collects the stream into a List
