[英]Reading and writing excel sheet using java apache POI
我正在使用Java Apache POI閱讀Excel工作表。 讀完后我想寫在同一行上,The ode讀得很好但不寫完,我想在每次迭代的每一行中創建第六列。...這是代碼

for (int rowIndex = 1; rowIndex <= 5; rowIndex++) {
Row row = firstSheet.getRow(rowIndex);
Cell cell = row.getCell(3);
String review = cell.getStringCellValue();
System.out.println(review);
String label =input.next();
row.createCell(6).setCellValue(label);
}
inputStream.close();
inputStream.close();
}
}
您僅在讀取文件而未在寫入文件。 最后,您必須輸入以下內容:
FileOutputStream out = new FileOutputStream(new File("..."));
workbook.write(out);
out.close();
