      {
         \"lat\":\"value\",
         \"lon\"         


        

Answer 1

If you want to add new value to an Object you can try the below as well

Before:

{
    "Name": "EnCoMa",
    "Manager": "Abhishek Kasetty"
 }

code :

JsonFactory factory = new JsonFactory();      
ObjectMapper mapper = new ObjectMapper(factory);
    ObjectWriter ow = new ObjectMapper().writer().withDefaultPrettyPrinter();
    String json = ow.writeValueAsString(TheObjectToWhichYouWantToAddNewValue);
    ObjectNode node = (ObjectNode) mapper.readTree(json);
    node.putPOJO("new Key","new value")

after:

{
    "Name": "EnCoMa",
    "Manager": "Abhishek Kasetty",
    "new Key": "new value"
}
