Question

I have a String of data called purchaseData which is separated into into lines with "\n" and into fields with "," (in CSV format).

How could I make a 2D string array so that the array contains arrays with each of the fields in. So for String[i][j], i would be the line value (position of row) and j would be the position of the field within the selected array of data (the row).

    String str = "YOUR_VERY_LONG_STRING";
    String[] lines = str.split("\n");
    String[][] linesCsv = new String[lines.length][];

    for (int i=0; i<lines.length; i++) {
        linesCsv[i] = lines[i].split(",");
    }
