Java。HSSF。Apache-poi。如何修改代碼

如果我很清楚，您只想過濾您的第一列字符串，然后單獨休息。

為什么不為此使用一個簡單的計數器：

while(rowIterator.hasNext()) { Row row = rowIterator.next(); String RowContent = null; Iterator<Cell> cellIterator = row.cellIterator(); while(cellIterator.hasNext()) {Cell cell = cellIterator.next();RowContent=RowContent+cell.toString(); } //Code for saving RowContent or printing or whatever you want for text in complete row}

RowContent將在每次迭代中串聯單個行的每個單元格。

我的數據以以下格式存儲（向下看）：[-]表示空白單元格，右邊可能只有10列（空格后）。像這樣的東西： [string0] [-] [string1] [string2] [string3] .. [string10] [-]

如何為以下代碼更改此代碼：

1）僅獲取[string0]

2）僅獲取[string1] [string2] [string3] .. [string10] [-]

try { FileInputStream file = new FileInputStream('C:Usersstudent3'+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 columnsIterator<Cell> cellIterator = row.cellIterator();while(cellIterator.hasNext()) { Cell cell = cellIterator.next(); switch(cell.getCellType()) {case Cell.CELL_TYPE_STRING: System.out.print(cell.getStringCellValue() + 'tt'); list1.add(cell.getStringCellValue()); break; }}System.out.println(''); } file.close(); FileOutputStream out = new FileOutputStream('C:Usersstudent3'+sfilename+'.xls'); workbook.write(out); out.close();

我不知道如何停止Iterator。他吸收了所有..
