InputStream inp = new FileInputStream("d:/Writefile.xls");    
		WorkbookSettings ws = new WorkbookSettings();
		Workbook wb = Workbook.getWorkbook(inp, ws);
		Sheet sheet = wb.getSheet(0);  
		//Cell cells[] = sheet.getRow(0);     
		//Cell cell = cells[0];
		//String cellContents = cell.getContents(); 
		//Modify the cellContents here     
		//Write the output to a file 		
		Number number;
		number = new Number(0, 0, 453.25, times);
		((WritableSheet) sheet).addCell(number);
		wb.close();

((WritableSheet) sheet).addCell(number);
