Question

I am getting a response String from server like below

    \"last_name\": \"Scott\",
            


        

Answer 1

    //import java.util.ArrayList;
    //import org.bson.Document;

    Document root = Document.parse("{\n"
            + "  \"name\": \"Json\",\n"
            + "  \"detail\": {\n"
            + "    \"first_name\": \"Json\",\n"
            + "    \"last_name\": \"Scott\",\n"
            + "    \"age\": \"23\"\n"
            + "  },\n"
            + "  \"status\": \"success\"\n"
            + "}");

    System.out.println(((String) root.get("name")));
    System.out.println(((String) ((Document) root.get("detail")).get("first_name")));
    System.out.println(((String) ((Document) root.get("detail")).get("last_name")));
    System.out.println(((String) ((Document) root.get("detail")).get("age")));
    System.out.println(((String) root.get("status")));
