I highly recommend that you use a library to handle instead doing it yourself. I guess your data is in CSV format, so you should take a look at common-csv.

You can resolve your problem with simple code:

CSVParser records = CSVParser.parse("abc,\"test,data\",valid", CSVFormat.DEFAULT);
for (CSVRecord csvRecord : records) {
    for (String value : csvRecord) {
        System.out.println(value);
    }
}

Output:

abc
test,data
valid
