Read CSV file

Hello,

I'm pretty new in Java, I try to read csv file into Data class. I use superCsv, but I have an error :(

Code:

---

Error while filling an object context: null offending processor: null
        at org.supercsv.io.CsvBeanReader.fillObject(Unknown Source)
        at org.supercsv.io.CsvBeanReader.read(Unknown Source)

Caused by: java.lang.InstantiationException: data.Data
        at java.lang.Class.newInstance0(Unknown Source)

Code:

        Locale.setDefault(Locale.US);
                               
                CsvPreference pref = new CsvPreference(';', ';', ";");
                FileReader fr = new FileReader(csvfile);
                ICsvBeanReader inFile  = new CsvBeanReader(fr, pref);
                       
                try{
               
                        Data data;
                        String[] header = inFile.getCSVHeader(true);                       
                       
                        while((data = inFile.read(Data.class, header, processors))!=null){
                               
                                System.out.println(data.getTime());
                                System.out.println(data.getVal1());
                               
                        }
                       
                       
                }
               
                finally{
                        inFile.close();
                }
               
        }
       
        static CellProcessor[] processors = new CellProcessor[]{
                       
                        new ParseDate("HH:mm:sss"),
                        new StrMinMax(1,30), //value 1,
                        null, // value 2
                        new StrMinMax(0, 20)// value 3
        };

actually value 1,2,3 are double, but I have error when I try to use ParseDouble, may be because values in CSV file has the following format #,#####.
Thank you.

For a moment change the content and give a try with a dummy file. Then you can make sure it. Since the exception you ends with not provide much details, seems that is the best way.

Oh, I've solved the problem, I used EXCEL_NORTH_EUROPE_PREFERENCE and it worked, and one of the name of the columns was with capitals "VA", but I had setVa, while setVA is correct. Anyway, Thnx a lot. :)

You are welcome (even I have not really helping you to solve the problem)

However, thanks a lot for posting that the way you solved it. There may be other members in the forums that stuck with the same issue.
