String to jsonobject in java [closed]

Answer 1

You can use GSON to parse JSON strings into Java objects and vice versa.

Answer 2

I suppose your input string is str,

 String str = {"xyz":[{"name":"apple","email_id":"apple@apple.com"}]}

 JSONObject json = JSONObject.fromObject(str);

 JSONArray jarr = json.getJSONArray("xyz");

Inplace of xyz, you can pass root string input.

This should work.

Answer 3

Use Google's JSON library (google-gson):

JsonParser jsonParser = new JsonParser();
JsonElement element = jsonParser.parse(your json string);

Answer 4

Use this one:

String jsonStr = "[{\"No\":\"1\",\"Name\":\"ABC\"},{\"No\":\"2\",\"Name\":\"PQR\"},{\"No\":\"3\",\"Name\":\"XYZ\"}]";

   JSONArray array = new JSONArray(jsonStr); 

    for(int i=0; i<array.length(); i++){
        JSONObject jsonObj  = array.getJSONObject(i);
        System.out.println(jsonObj.getString("No"));
        System.out.println(jsonObj.getString("Name"));
    }

Output:

1
ABC
2
PQR
3
XYZ
