  public class ReadExcel {
  
  public static ArrayList<String> record;
  
  public static void main(String[] args) throws FileNotFoundException, IOException {
  
   //---Read file---
  FileInputStream in = new FileInputStream("test1.xlsx");
  XSSFWorkbook workbook = new XSSFWorkbook(in);

  XSSFRow row;
  Cell cell;
  
  Iterator<Row> rowIterator = spreadsheet.iterator();
  
  while(rowIterator.hasNext()){
      record = new ArrayList<String>();
      row = (XSSFRow)rowIterator.next();
  
      if(row.getRowNum()==0) {
          continue;
      }
  
       for(int k = 0; k < row.getLastCellNum();k++){
          cell = row.getCell(k, Row.CREATE_NULL_AS_BLANK);
      }
  
      Iterator<Cell> cellIterator = row.cellIterator();
  
      while(cellIterator.hasNext()){
              cell = cellIterator.next();
              cell.setCellType(Cell.CELL_TYPE_STRING); 
  
              switch(cell.getCellType()){
                  case Cell.CELL_TYPE_STRING:
                      record.add(cell.getStringCellValue());
                      System.out.print(cell.getStringCellValue());
                      break;
                  case Cell.CELL_TYPE_NUMERIC:
                      Double value = cell.getNumericCellValue();
                      Long longValue = value.longValue();
  
                      record.add(Double.toString(cell.getNumericCellValue()));
                      System.out.print(cell.getNumericCellValue());
                      break;
              }
          }   
          System.out.println();
  
          String name = record.get(0);
          String gender = record.get(1);
          String age = record.get(2);
          String dateLeave = record.get(3);  //[ERROR]
  
          System.out.println(name + gender + age + dateLeave);
          }
      }
  }
  

但是，从我上面的程序中，我得到了这个异常：

Exception in thread "main" java.lang.IndexOutOfBoundsException: Index: 3, Size: 3
at java.util.ArrayList.rangeCheck(ArrayList.java:653)
at java.util.ArrayList.get(ArrayList.java:429)
at ibguobform.ReadExcel.main(ReadExcel.java:66)
Java Result: 1

我犯了什么错误？
