 public static void main(String args[]) throws UnknownHostException {
  DB database = getDatabase();
  DBCollection collection = database.getCollection("loans");

  // To Find All the Records
  DBCursor cursor = collection.find();
  while(cursor.hasNext()) {
      System.out.println("Record - " + cursor.next());
