        try {
            File file = new File("myfile.txt"); // java.io.File
            sc = new Scanner(file);     // java.util.Scanner
            String line;
            while (sc.hasNextLine()) {
              line = sc.nextLine();
              // process the line
            }
          }
          catch(FileNotFoundException e)
          {
              e.printStackTrace();
