Answer 1

You could use a method like this and provide the path to the file you wish to read from. This creates a Scanner to read from the file passed in.

It grabs each line one at a time and adds a new CarOwner(String,String,String,String,String) object to the result array.

P.S. i have no idea your implementation of CarOwner so i just used all Strings... I'll leave that to you to figure out heh.

public ArrayList < CarOwner > processTextToCarOwnerList(String filePath) throws IOException {
    ArrayList < CarOwner > result = new ArrayList < CarOwner > ();
    Scanner scan = new Scanner(new File(filePath));
    while (scan.hasNextLine()) {
        String line = scan.nextLine();
        String[] lineArray = line.split(" ");
        result.add(new CarOwner(lineArray[0], lineArray[1], lineArray[2], lineArray[3], lineArray[4]));
        }
        return result;
    }

Answer 2

You could use something like this:

ArrayList<CarOwner> owners = new ArrayList<CarOwner>();

BufferedReader br = new BufferedReader(new FileReader(new File("path/to/your/file.csv")));
String line;
while ((line = br.readLine()) != null) {

    String[] entries = line.split(",");

    CarOwner owner = new CarOwner(entires[0], entries[1], entries[2], entries[3]);

    owners.add(owner);
}

Do you have a real csv file (all values separated by ,) or are they separated by spaces or something like that? In that case you'd have to replace the , with spaces.
