Retrieve All Field Values From From JSON Object Or ObjectNode

To retrieve all field values from an ObjectNode, use elements() method which returns an Iterator of JsonNode.

Example Code for Json Object:

{
       "firstname" : "Phani",
       "lastname" : "Nagula"
}
// Create an object to ObjectMapper
ObjectMapper objectMapper = new ObjectMapper();
		
// Creating Node that maps to JSON Object structures in JSON content
ObjectNode employeeInfo = objectMapper.createObjectNode();

employeeInfo.put("firstname", "Phani");
employeeInfo.put("lastname", "Nagula");


// To get all field values
Iterator allFieldValues = employeeInfo.elements();
System.out.println("Fields values are : ");
while(allFieldValues.hasNext())
{
    System.out.println(allFieldValues.next());
}
