I followed this mongodb documentation. Here is my code
public class JMongoDBCDemo
{
MongoClient mongoClient;
DB db;
DBCollection coll;
public JMongoDBCDemo()
{
MongoClient mongoClient = new MongoClient( "localhost" , 27017 );
db = mongoClient.getDB( "messenger" );
coll = db.getCollection("users");
DBObject myDoc = coll.findOne();
System.out.println(myDoc);
mongoClient.close();
System.out.println("Got a collection...");
}
public static void main(String[] args){
JMongoDBCDemo mongoDemo = new JMongoDBCDemo();
}
}
Below is the output

Got a collection... //my output
according to documentation it should print like
{ "_id" : { "$oid" : "55201cec68fb70b6affba026"} , "name" : "prasad" , "password" : "123456"}
Got a collection...
So can any one please help me to prevent these logs in console.
This is configurable within the Java code. This means, ideally, you should have one Mongo Client instance per JVM. So, the application's client uses a connection from the pool and returns it back to the connection pool after its usage. There is no need for closing the connection explicitly.
Before you start using MongoDB in your Java programs, you need to make sure that you have MongoDB CLIENT and Java set up on the machine. You can check Java tutorial for Java installation on your machine. Now, let us check how to set up MongoDB CLIENT. You need to download the jar mongodb-driver-3.11.
All Connection methods are thread safe, and Connection handles can be shared between threads.
Thanks to @jyemin By using MongoDB official documentation link
Logger mongoLogger = Logger.getLogger( "org.mongodb.driver" );
mongoLogger.setLevel(Level.SEVERE);
Now no logs are there in the console.
i tried this java.util.logging.Logger.getLogger("org.mongodb.driver").setLevel(Level.OFF);
it not worked, it still logs com.mongodb.diagnostics.logging.JULLogger log
I changed it to JULLogger and it worked
java.util.logging.Logger.getLogger("JULLogger").setLevel(Level.OFF);
