importing CSV data into Database in java when the no of columns are known using javacsv

I have imported CSV data into postgres Database in java using javaCSV jar. But now i have to convert it in such way that if the no of columns in the csv are not known then also i should be able to import it. But the condition i can use only javaCSv jar. No other jar is allowed. And also the performance should not degrade if i insert 100000 records. Here is my code-

DataImport.java

package programs;
public class DataImport {
            public static void main(String[] args) {
                        CSVLoader csvLoader=new CSVLoader();
            String fileName="D:/File1.csv";
            csvLoader.loadCSV(fileName);
                    }
}

CSVLoader.java

package programs;
import java.io.FileNotFoundException;
import java.io.FileReader;

public class CSVLoader {
    static CSVToDB cd   = new CSVToDB();

    public CSVLoader(char seprator) {
        super();
        this.seprator = seprator;
    }

    public void loadCSV(String fileName) {
        CsvReader products = null;
        try {
            products = new CsvReader(fileName);

        } catch (FileNotFoundException e) {
            e.printStackTrace();
        }
        cd.retrieveData(products);
        products.close();
    }


}

    void retrieveData(CsvReader products) {

        try {

            c = ConnectionManager.getConnection();
            System.out.println(products.readHeaders());

            System.out.println(products.getHeaderCount());
            String a;

            stmt = c.prepareStatement("insert into csvtodb values(?,?,?)");
            final int batchSize = 1000;
            int count = 0;
        while (products.readRecord()) {

                stmt.setString(1, products.get("Name"));
                stmt.setString(2, products.get("Address"));
                stmt.setString(3, products.get("City"));
                stmt.addBatch();
                if (++count % batchSize == 0) {
                    stmt.executeBatch();
                }
            }

            stmt.executeBatch();
        } catch (Exception e) {
            System.err.println(e.getClass().getName() + " : " + e.getMessage());
            System.exit(0);
        } finally {
            try {

                products.close();
