我的数据以一种格式存储(向下看):[-] 表示空白单元格,右侧可能只有 10 列,在空格之后。像这样:
[string0] [-] [string1] [string2] [string3] .. [string10] [-]
如何将此代码更改为:
1) 仅获取 [string0]
2) 仅获取 [string1] [string2] [string3] .. [string10] [-]
try {
FileInputStream file = new FileInputStream("C:\\Users\\student3\\"+sfilename+".xls");
//Get the workbook instance for XLS file
HSSFWorkbook workbook = new HSSFWorkbook(file);
//Get first sheet from the workbook
HSSFSheet sheet = workbook.getSheetAt(0);
//Iterate through each rows from first sheet
Iterator<Row> rowIterator = sheet.iterator();
while(rowIterator.hasNext()) {
Row row = rowIterator.next();
//For each row, iterate through each columns
Iterator<Cell> cellIterator = row.cellIterator();
while(cellIterator.hasNext()) {
Cell cell = cellIterator.next();
switch(cell.getCellType()) {
case Cell.CELL_TYPE_STRING:
System.out.print(cell.getStringCellValue() + "\t\t");
list1.add(cell.getStringCellValue());
break;
}
}
System.out.println("");
}
file.close();
FileOutputStream out =
new FileOutputStream("C:\\Users\\student3\\"+sfilename+".xls");
workbook.write(out);
out.close();
我不知道如何停止迭代器。他吸收了所有..
