I'm new to mongo, I'm trying to make an insert in the bank but it's the problem at the time of inserting

import com.mongodb.BasicDBObject;
import com.mongodb.DB;
import com.mongodb.DBCollection;
import com.mongodb.MongoClient;

    public class InsertDriver {
        public static void main(String[] args) throws UnknownHostException {
            DB dB = (new MongoClient("localhost", 27017)).getDB("realdatabase");
            DBCollection dBCollection = dB.getCollection("Channel");
            BasicDBObject basicDBObject = new BasicDBObject();
            basicDBObject.put("name", "guilherme");
            basicDBObject.put("state", "happy");
            dBCollection.insert(basicDBObject);

        }
    }

Error: (14, 21) java: no suitable method found for insert (com.mongodb.BasicDBObject) method com.mongodb.DBCollection.insert (com.mongodb.DBObject ...) is not applicable (argument mismatch; com.mongodb.BasicDBObject can not be converted to com.mongodb.DBObject []) method com.mongodb.DBCollection.insert (java.util.List) is not applicable (argument mismatch; com.mongodb.BasicDBObject can not be converted to java.util.List)

The installation to work would be two .jar :

NetBeans Development Environment

Code worked after the installation of these two packages:

import com.mongodb.BasicDBObject;
import com.mongodb.DB;
import com.mongodb.DBCollection;
import com.mongodb.MongoClient;

MongoClient mongoClient = new MongoClient("localhost", 27017);
DB db = mongoClient.getDB("realdatabase");        
DBCollection collection = db.getCollection("channel");
BasicDBObject basicDBObject = new BasicDBObject();
basicDBObject.put("name", "guilherme");
basicDBObject.put("state", "happy");
collection.insert(basicDBObject);

But the ~~getDB~~ method is obsolete, and soon will not work. Then use the method getDatabase , MongoDatabase and MongoCollection<Document> which are the most current.

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

MongoClient mongoClient = new MongoClient(new ServerAddress("localhost", 27017));
MongoDatabase database = mongoClient.getDatabase("realdatabase");                
MongoCollection<Document> collection = database.getCollection("channel");

Document doc = new Document();
doc.put("name", "somalia");
doc.put("state", "casado");

collection.insertOne(doc);

IntelliJ Development Environment

There are also two .jar
