I'm trying to read a csv file to a 2D array in Java.

So far I manage to follow some stackoverflow examples and successfully read the .csv using opencsv-3.2.

    CSVReader csvReader = new CSVReader(new FileReader(new File("file.txt")));
    List<String[]> list = csvReader.readAll();

    String[][] dataArr = new String[list.size()][];
    dataArr = list.toArray(dataArr);

However I would like to dataArr be on float type and not on String. I probably imagine that we have to convert the String list to float, but despite several attempts and some reading I still do not have success. Thanks
