 package com.mongo;import java.util.ArrayList;import java.util.List;import org.bson.Document;import com.mongodb.MongoClient;import com.mongodb.client.MongoCollection;import com.mongodb.client.MongoDatabase;
public class MongoTest {
   public static void main(String[] args) {
       MongoClient mongoClient = new MongoClient("localhost", 27017);
       MongoDatabase mongoDatabase = mongoClient.getDatabase("student");
       MongoCollection<Document> collection = mongoDatabase
               .getCollection("student");
       Document document = new Document("name", "scofield").append(
               "score",
               new Document("English", 45).append("Math", 89).append(

       List<Document> documents = new ArrayList<Document>();
