        // TODO Auto-generated method stub
             ExcelJxl.WriteFile("D:\nimit.xls");
    }

    public static void WriteFile(String path) throws BiffException, IOException, RowsExceededException, WriteException{

    Workbook wb=Workbook.getWorkbook(new File(path));

    WritableWorkbook copy=Workbook.createWorkbook(new File("D:\temp.xls"),wb);
    WritableSheet sheet = copy.getSheet(1); 
    WritableCell cell = sheet.getWritableCell(0,0); 
    String S="nimit";
    if (cell.getType() == CellType.LABEL) 
    { 
      LabelCell l = (LabelCell) cell; 
      l.setString(S); 
    }
    copy.write(); 
    copy.close();
    wb.close();

    }
   }

我已经编辑了我的程序，现在它说 setString()方法 setString(String) 未定义类型 LabelCell我阅读了文档，在 LabelCell 类型中有一个方法 setString。

LabelCell 只是一个只有一种方法的接口，getString()您可以在此处了解更多信息

你应该jxl.write.Label改用。
您应该做的如下
您应该导入以下文件

import jxl.write.Label

然后以下是将所需位置的单元格添加到excel文件的代码

Workbook existingWorkbook = Workbook.getWorkbook(new File(fileToEdit.getAbsolutePath()));
WritableWorkbook workbookCopy = Workbook.createWorkbook(new File("output.xls"), existingWorkbook);
WritableSheet sheetToEdit = workbookCopy.getSheet(sheetName);
WritableCell cell;
Label l = new Label(currentColumn, currentRow, value);
cell = (WritableCell) l;
sheetToEdit.addCell(cell);
 workbookCopy.write();
 workbookCopy.close();
 existingWorkbook.close();

currentColumn并currentRow定义索引和值包含要放置在该单元格中的字符串。

希望能帮助到你
