Reading semicolon delimited csv

Question

I have the below block of code which uses OpenCSV to read a CSV file and store the 7th column. The problem I face is that I use ; as delimiter in the CSV file but it takes , as delimiter as well. How can I avoid this?

Putting "" in CSV is not possible, since we get a non-editable file from client.

        CSVReader reader = null;
    String[] nextCsvLine = new String[50];
    String splitBy = ";";

    int count = 0;

    try {
        StringReader sr = new StringReader(new String(in, offset, len));
        reader = new CSVReader(sr);

        while ((nextCsvLine = reader.readNext()) != null) {
            for (String linewithsemicolon : nextCsvLine) {
                log.debug("Line read : "+linewithsemicolon);
                String[] b = linewithsemicolon.split(splitBy);
                if (count==0){
                    count++;
                    continue;
                }
                else    {      
                    detailItems.add(b[7]);
                    log.debug("7th position: "+b[7]);
                    count++;
                }                   
            }

Use the overloaded version with separator of OpenCSV

CSVReader(reader, ';')

Update (thanks to @Matt) - better use:

CSVReaderBuilder(reader)
    .withCSVParser(new CSVParserBuilder()
        .withSeparator(';')
        .build()
    ).build()

I think the counting was done a bit wrong:

try (CSVReader reader = new CSVReader(sr, ';')) {
    String[] nextCsvLine;
    while ((nextCsvLine = reader.readNext()) != null) {
        int count = 0;
        for (String field: nextCsvLine) {
            log.debug("Line read : "+linewithsemicolon);
            if (count == 6) { // 7th column
                detailItems.add(field);
                log.debug("7th position: " + field);
            }                   
            count++;
        }
    }

Instead the for-loop you could have done:

         if (nextCsvLine.length > 6) {
             detailItems.add(nextCsvLine[6]);
         }

Where the seventh field should have index 6.
