Convert json array to arraylist and Arraylist to jsonArray

1) Convert json array to arraylist

Gson gson = new Gson();
JSONArray jsonArray = NetworkUtilities.getData("mymodeldata");

Type listType = new TypeToken<List<MyModel>>(){}.getType();
List<MyModel> myModelList = gson.fromJson(jsonArray, listType);

2)Arraylist to jsonArray

List<Customer> customerList = CustomerDB.selectAll();

JsonArray result = (JsonArray) new Gson().toJsonTree(customerList,
            new TypeToken<List<Customer>>() {
            }.getType());


 public class Test {

  public static void main (String[] args) {

    // Initialize a list of type DataObject
    List<DataObject> objList = new ArrayList<DataObject>();
    objList.add(new DataObject(0, "zero"));
    objList.add(new DataObject(1, "one"));
    objList.add(new DataObject(2, "two"));

    // Convert the object to a JSON string
    String json = new Gson().toJson(objList);
    System.out.println(json);

    // Now convert the JSON string back to your java object
    Type type = new TypeToken<List<DataObject>>(){}.getType();
    List<DataObject> inpList = new Gson().fromJson(json, type);
    for (int i=0;i<inpList.size();i++) {
      DataObject x = inpList.get(i);
      System.out.println(x);
    }

  }
