To convert the map to JSON, use the Jsonobject object:

map<string, object> map = new hashmap<string, object> ();

Map.put ("UserId", 1001);

Map.put ("UserName", "Zhang San");

Map.put ("Usersex", "male");

Jsonobject jsonobject = jsonobject.fromobject (map);

System.out.println (Jsonobject);

To convert an array to JSON:

String[] arr = {"ASD", "DFGD", "ASD", "234"};

Jsonarray Jsonarray = Jsonarray.fromobject (arr);

System.out.println (Jsonarray);
