Unreacable code @ Cell cell = cellIterator.next(); : Help please. I am coding a program to format the contents of an excel file. Eclipse is saying that the code is unreachable and I don't understand why.Where did I go wrong? Thanks for the help. :)

    private String formatExcel(File excel)
  {
    this.statusLabel.setText("formatting...");
    try
    {
      FileInputStream file = new FileInputStream(excel);
      try

      }

      try
      {
        sheetNum = Integer.parseInt(this.sheetNumber.getText());
      }
      catch (NumberFormatException e)
      {
        file.close();
      }
      if ((sheetNum < 1) || (sheetNum > this.workbook.getNumberOfSheets()))
      {
        file.close();
        return "Please input a valid sheet number.";
      }
      Sheet sheet = this.workbook.getSheetAt(sheetNum - 1);
      sheet.setZoom(17, 20);
