JavaでJsonParserSequenceを使用して2つのJSON文字列を順番にマージするにはどうすればよいですか?

public static JsonParserSequence createFlattened(JsonParser first, JsonParser second)

import java.io.*;
import com.fasterxml.jackson.core.*;
import com.fasterxml.jackson.core.util.*;
public class JsonParserSequenceTest {
   public static void main(String[] args) throws JsonParseException, IOException {
      String jsonString1 = "{\"id\":\"101\", \"name\":\"Ravi Chandra\", \"address\":\"Pune\"}";
      String jsonString2 = "{\"id\":\"102\", \"name\":\"Raja Ramesh\", \"address\":\"Hyderabad\", \"contacts\":[{\"mobile\":\"9959984805\", \"home\":\"7702144400\"}]}";
      JsonFactory jsonFactory = new JsonFactory();
      JsonParser jsonParser1 = jsonFactory.createParser(jsonString1);
      JsonParser jsonParser2 = jsonFactory.createParser(jsonString2);
      JsonParserSequence jsonParserSequence = JsonParserSequence.createFlattened(jsonParser1, jsonParser2);
      JsonToken jsonToken = jsonParserSequence.nextToken();
         while(jsonToken != null) {
            switch(jsonToken) {
               case FIELD_NAME: System.out.println("Key field: " + jsonParserSequence.getText());
               break;
               case VALUE_FALSE:
               case VALUE_NULL:
               case VALUE_NUMBER_FLOAT:
               case VALUE_NUMBER_INT:
               case VALUE_STRING:
               case VALUE_TRUE: System.out.println("Key value: " + jsonParserSequence.getText());
               break;
            }
            jsonToken = jsonParserSequence.nextToken();
         }
      jsonParserSequence.close();
   }
}
