I cannot insert into Mongodb using Java

Question

I’m new in Mongo, I’m trying to make an Insert in the bank but it’s a problem when 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 cannot be converted to com.mongodb.Dbobject[]) method com.mongodb.Dbcollection.Insert(java.util.List) is not applicable (argument Mismatch; com.mongodb.Basicdbobject cannot be converted to java.util.List)

The installation to work would be two .jar:

• mongodb-driver-core-3.0.4.jar
• Mongo-java-driver-3.0.0.jar

Netbeans Development Environment

Code worked after installing 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);

only that the method getDB is obsolete, and soon will not work.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);

There are also two .jar

• Mongo-java-driver-2.13. 3.jar
• bson-2.13.3.jar
