如何使用poi jars處理空單元?這是代碼:如何使用apache-poi處理空單元
public static String getdata(String SheetName, String ObjectLabel, int row) throws InvalidFormatException, IOException{
String objvalue = null;
FileInputStream fi = new FileInputStream(dir + "\\src\\pack\\TaurusRefactored\\TaurusRegistration1.xls");
Workbook w = WorkbookFactory.create(fi);
Sheet s = w.getSheet(SheetName);
int rowcount = s.getLastRowNum();
int columncount = s.getRow(0).getLastCellNum();
for (int i = 0; i < columncount; i++) {
String objlabl = s.getRow(0).getCell(i).getStringCellValue();
if (objlabl.equals(ObjectLabel)) {
switch (s.getRow(row).getCell(i).getCellType()) {
case Cell.CELL_TYPE_STRING:
objvalue = s.getRow(row).getCell(i).getStringCellValue().trim();
break;
case Cell.CELL_TYPE_NUMERIC:
objvalue = Integer.toString((int) s.getRow(row).getCell(i).getNumericCellValue());
break;
case Cell.CELL_TYPE_BLANK:
objvalue = "";
default:
break;
}
}
}
return objvalue;
}
我得到了錯誤的開關語句:(s.getRow(row).getCell(i).getCellType())
而從空電池獲取的數據。
這與硒有什麼關係?!?! – SiKing 2014-11-21 21:57:56
