有没有办法从ArrayList内部的mongodb访问JSON文档的值？

import com.mongodb.MongoClient;
import com.mongodb.client.MongoCollection;
import com.mongodb.client.MongoCursor;
import com.mongodb.client.MongoDatabase;
import org.bson.Document;

import java.util.ArrayList;
import java.util.List;

public class MongoDBExample {
    public static void main(String[] args) {
        // 连接到MongoDB数据库
        MongoClient mongoClient = new MongoClient("localhost", 27017);

        // 获取数据库对象
        MongoDatabase database = mongoClient.getDatabase("mydb");

        // 获取集合对象
        MongoCollection<Document> collection = database.getCollection("mycollection");

        // 创建查询条件
        Document query = new Document("name", "John");

        // 执行查询操作
        MongoCursor<Document> cursor = collection.find(query).iterator();

        // 遍历查询结果集
        while (cursor.hasNext()) {
            Document document = cursor.next();
            String name = document.getString("name");
            int age = document.getInteger("age");
            System.out.println("Name: " + name + ", Age: " + age);
        }

        // 关闭连接
        mongoClient.close();
    }
}
