Adding a List to Json ObjectNode

Question

ObjectNode row = Json.newObject();
row.put("0", a);
row.put("1", x);
row.put("2", y);

now I have list

List<String> list = new ArrayList<String>();

How can I add this to the row?

Answer 1

You can use the putArray method which creates an ArrayNode. Then you should fill it with the elements from your list.

ArrayNode arrayNode = row.putArray("myList");
for (String item : list) {
    arrayNode.add(item);
}
