如何使用Java中的jena将从csv读取的行数中的数据插入到rdf文件中？

Question

try {

        br = new BufferedReader(new FileReader(csvFile));
        final Resource FlightOperations = model.createResource(NS+"FlightOperations");

        int i=0;
        while ((line = br.readLine()) != null) {
            //  j++;

            String[] flightOperation = line.split(cvsSplitBy);

            model.addLiteral (FlightOperations, rowID, i);
            model.addLiteral (FlightOperations, DataExtractDate, ResourceFactory.createTypedLiteral(flightOperation[0], XSDDatatype.XSDdate));
            model.addLiteral (FlightOperations, ReportPeriod, ResourceFactory.createTypedLiteral(flightOperation[1], XSDDatatype.XSDdate));
            model.addLiteral (FlightOperations, FlightType, ResourceFactory.createTypedLiteral(flightOperation[2], XSDDatatype.XSDstring));
            model.addLiteral (FlightOperations, arrival_departure, ResourceFactory.createTypedLiteral(flightOperation[3], XSDDatatype.XSDstring));
            model.addLiteral (FlightOperations, domestic_international, ResourceFactory.createTypedLiteral(flightOperation[4], XSDDatatype.XSDstring));
            model.addLiteral (FlightOperations, flightOpsCount, ResourceFactory.createTypedLiteral(flightOperation[5], XSDDatatype.XSDint));

            i++;
        }
    }
    catch (FileNotFoundException e) {
        e.printStackTrace();
    }

I am not able to print the the values in the correct order that are in the ccsv file. I want to build rdf with 1369 rows of csv. enter image description here

An RDF graph does not preserve order.

If you are simply printing the RDF, it does not matter.

If you are querying the RDF, sort by the recorded row number rowID .
