如何解决Java。HSSF。Apache-poi。如何修改代码?

如果我很清楚,您只想过滤您的第一列字符串,然后单独休息。

为什么不为此使用一个简单的计数器:

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将在每次迭代中串联单个行的每个单元格。

解决方法

我的数据以以下格式存储(向下看):[-]表示空白单元格,右边可能只有10列(空格后)。像这样的东西: [string0] [-] [string1] [string2] [string3] .. [string10] [-]

如何为以下代码更改此代码:

1)仅获取[string0]

2)仅获取[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..
