cont. on java apache poi (part 1)

Code

...
while(rowIterator.hasNext()){
    List<String> record = new ArrayList<String>();

    row = (XSSFRow)rowIterator.next();

    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());
                break;
            case Cell.CELL_TYPE_NUMERIC:
                record.add(Double.toString
                (cell.getNumericCellValue()));
            break;
        }
    }
    readFile();
}

public void readFile(){
    String ID = record.get(0);
    System.out.println(ID);
}
...

From above code, my output is like below:
ID
1
2
3
My expected output should like this:
1
2
3
My question is how to remove the first row from excel (ID) from the above code?

回答1:

To skip the first row:

while(rowIterator.hasNext()){

    row = (XSSFRow)rowIterator.next();

    if(row.getRowNum()==0) {
        continue;
    }

    List<String> record = new ArrayList<String>();
    Iterator<Cell> cellIterator = row.cellIterator();
    ...
    readFile();
}

回答2:

Add rowIterator.next(); above the While loop in the program which ignore the first row.So simple.Hope this helps you.

 **rowIterator.next();**
            while (rowIterator.hasNext())
            {
                Row row = rowIterator.next();
                //For each row, iterate through all the columns
                Iterator<Cell> cellIterator = row.cellIterator();

                while (cellIterator.hasNext())
                {
                    Cell cell = cellIterator.next();
                    //Check the cell type and format accordingly
                    switch (cell.getCellType())
                    {
                        case Cell.CELL_TYPE_NUMERIC:
                            System.out.print(cell.getNumericCellValue() + "t");
                            break;
                        case Cell.CELL_TYPE_STRING:
                            System.out.print(cell.getStringCellValue() + "t");
                            break;
                    }
                }
                System.out.println("");
            }
            file.close();
        }
        catch (Exception e)
        {
            e.printStackTrace();
        }
    }
