How to use MongoClientOptions instead of MongoOptions?

Use the writeConcern method on the builder, as in:

MongoClientOptions options = MongoClientOptions.builder()                                               .writeConcern(WriteConcern.JOURNALED)                                               .build();

or

Things are quite a bit more complicated with client version 3.6. You'll have to instantiate a WriteConcern and use it with MongoClientOptions.Builder. Example:

import com.mongodb.MongoClient;import com.mongodb.MongoClientOptions;import com.mongodb.ServerAddress;import com.mongodb.WriteConcern;import com.mongodb.WriteConcernError;public class MongoOptionsSample{    public static void main( String[] args )    {        WriteConcern l_concern = new WriteConcern( wVal, wTimeoutMS )                .withJournal( bool );        MongoClientOptions l_opts =                MongoClientOptions                .builder()                .writeConcern( l_concern )                .build();        ServerAddress l_addr = new ServerAddress( "localhost", 27017 );        try        (                MongoClient l_conn = new MongoClient( l_addr, l_opts );        )        {            ...        }    }}

Fsync and safe are deprecated. See the WriteConcern documentation for details.

You can use like below:You can set the read prefernece and write concern using object of new Mongoclient...There are list of apis are available .Please check the below format..

        MongoClient c =  new MongoClient(new MongoClientURI("mongodb://localhost"));        DB db = c.getDB("final");        DBCollection animals = db.getCollection("emp");        BasicDBObject animal = new BasicDBObject("emp", "john");MongoClientOptions options = new MongoClient().setReadPreference(preference);MongoClientOptions options = new MongoClient().setWriteConcern(concern);  

You can add fsynk aswell..

MongoClientOptions options = new MongoClient().fsync(async)
