This will work:

CommandResult resultSet = db.getCollection("emp").getStats();
        System.out.println(resultSet);

It remains hard coded to 1.0 for compatibility only." , "userFlags" : 1 , "capped" : false , "nindexes" : 1 , "indexDetails" : { } , "totalIndexSize" : 8176 , "indexSizes" : { "_id_" : 8176} , "ok" : 1.0}
