如何獲得Excel工作表的每一行和每一列的值

Question

我有一個excel文件，代碼工作正常，但是如何以不同的方式獲取每個列和行的值，以便可以將值存儲在數據庫中。 先感謝您

public class excel_demo {
public static void main(String[] args) {
    try {
        FileInputStream file = new FileInputStream(new File("C:\\Users\\Admin\\Downloads\\ExcelDemosWithPOI\\howtodoinjava_demo.xlsx"));

        //Create Workbook instance holding reference to .xlsx file
        XSSFWorkbook workbook = new XSSFWorkbook(file);

        //Get first/desired sheet from the workbook
        XSSFSheet sheet = workbook.getSheetAt(0);

        //Iterate through each rows one by one
        Iterator<Row> rowIterator = sheet.iterator();
        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();
    }
}

}

下載JEXCEL api，並使用此代碼，

import jxl.*;//import jxl package.


File excelSheet = null;
Workbook workbook = null;
Workbook wb = Workbook.getWorkbook(new File(destFile));//destFile is excel file
Sheet sheet = wb.getSheet(sheetNo);
columns = sheet.getColumns();
rows = sheet.getRows();
for(int row = 0;row <rows;row++)
{
   for(int col =0;col <columns;col++)
   {
      a[row][col] =Integer.parseInt( sheet.getCell(col,row).getContents());
   }
}

希望這可以幫助..
