how to convert JSON Array to arraylist

Hi,

I'm receiving data in form of JSON Array. Here's the JSON Array that i've received :
[{"FOODID":"Jus Alpukat","PRICE":"7000","NUM":"1","RES":"7000.0","ORDERID_FK":""},{"FOODID":"Ice Cream","PRICE":"5000","NUM":"10","RES":"50000.0","ORDERID_FK":""}]

i need it to be converted into arraylist that will be inserted into JTable into java. I've read about GSON and a few article to do this but i still don't understand. Can you give me example how to do this? thanks.

Hi Melody,

You can use jackson library to convert json object to arraylist,

first, you need to create a POJO

public class Food{ private String foodId; private int price; private int res; private int orderIdFk; //... etc }

second , create a method that convert to ArrayList Object, let say a convert method.

public void convert() throws JsonParseException, JsonMappingException, IOException {    ObjectMapper objectMapper = new ObjectMapper();    List<Food> foods = objectMapper.readValue(jsonString,objectMapper.getTypeFactory().constructCollectionType(List.class, Food.class)); }

Hope it helps
