    MongoClient mongoClient = null;
    try {
      mongoClient = new MongoClient("localhost", 27017);
    } catch (Exception e) {
      e.printStackTrace();
    }
    return mongoClient;
  }
  
  public static void main(String[] args) throws Exception {   
    MongoClient mongoClient = getMongoClient();
    
    /* Step 2: Connect to DB */
    DB db = mongoClient.getDB("test");
    
    /*Step 3 : Get collection */
