DBCollection collection = db.createCollection("employee", null);

import java.net.UnknownHostException;
import com.mongodb.MongoClient;
import com.mongodb.DB;
import com.mongodb.DBCollection;


public class DatabaseConnect {

/* Step 1 : get mongoCLient */
public static MongoClient getMongoClient(){
MongoClient mongoClient = null;
try {
mongoClient = new MongoClient( "localhost" , 27017 );
} catch (UnknownHostException e) {
e.printStackTrace();
}
return mongoClient;
}

public static void main(String args[]){
MongoClient mongoClient = getMongoClient();

/* Step 2: Connect to DB */
DB db = mongoClient.getDB("sample");

DBCollection collection = db.createCollection("employee", null);

System.out.println("Collection created ");
System.out.println("Collection employee belongs to db " + collection.getDB());
}
}
