完成程序填空，实例化一个mongo客户端,服务器地址：localhost(本地)，端口号：27017，实例化一个mongo数据库mycol, 创建集合 test,获取数据库中集合test,在集合test中插入内容为"name","zhangsan"的一条文档，打印输出“Connect to database successfully”，利用try-catch机制捕获异常，输出打印错误信息。 public class MongoDBJDBC{ public static void main( String args[] ){ try{ // 连接到 mongodb 服务 MongoClient mongoClient = new MongoClient( __(1)__); // 连接到数据库 MongoDatabase mongoDatabase = mongoClient.getDatabase("mycol"); mongoDatabase. _____(2)___("test"); MongoCollection collection = mongoDatabase.getCollection("test"); collection.insertOne(new Document().__(3)__("name","zhangsan")); System.out.println("Connect to database successfully"); FindIterable findIterable = collection.find(); MongoCursor mongoCursor = findIterable.__(4)__; while(mongoCursor.__(5)__){ System.out.printIn(mongoCursor.next()); } System.out.printIn("文档插入成功"); }catch(Exception e){ System.err.printIn( e.getClass().getName() + ": "' + e.getMessage() );｝｝｝

以下是代码的完整版，其中__(1)__、__(2)__、__(3)__、__(4)__、__(5)__需要填入相应的内容：

public class MongoDBJDBC{
    public static void main( String args[] ){
        try{
            // 连接到 mongodb 服务
            MongoClient mongoClient = new MongoClient("localhost", 27017 ); // (1)
            
            // 连接到数据库
            MongoDatabase mongoDatabase = mongoClient.getDatabase("mycol");
            mongoDatabase.createCollection("test");
            
            MongoCollection<Document> collection = mongoDatabase.getCollection("test");
            collection.insertOne(new Document().append("name","zhangsan")); // (3)
            
            System.out.println("Connect to database successfully");
            
            FindIterable<Document> findIterable = collection.find();
            MongoCursor<Document> mongoCursor = findIterable.iterator(); // (4)
            while(mongoCursor.hasNext()){
                System.out.println(mongoCursor.next());
            }
            
            System.out.println("文档插入成功");
        }catch(Exception e){
            System.err.println( e.getClass().getName() + ": " + e.getMessage() );
        }
    }
}
