public class TradeSim {
    public void readFile(String fileName) {
        try {
            // file name and absolute path
            File file = new File(fileName);
            String fullPath = file.getAbsolutePath();
            System.out.println("Using file:n" + fullPath + "n");

            // set File Input Stream to Full Path
            FileInputStream inputStream = new FileInputStream(fullPath);

            // open input stream and retrieve data
            Scanner scanner = new Scanner(inputStream);
            scanner.useDelimiter(System.getProperty("line.separator"));
            while (scanner.hasNext()) {
                String data = scanner.next(); // gets a whole line

            }
            scanner.close();

    }

    public void parseCSVLine(String line) {
        Scanner scanner = new Scanner(line);
        scanner.useDelimiter(",");
        long timeStamp = scanner.nextLong();
        System.out.println("timeStamp: " + timeStamp);
        String symbol = scanner.next();

        int price = scanner.nextInt(); //Error occurs here!!
