例如,我正在将Excel中的数据解析为Eclipse中的java项目。我最终将它传递给一些描述的数据库,但是我现在正在使用system.out.println语句来查看正在解析的文件数量。这就是我的困惑所在,excel表中有36,616行,但我使用的解析代码只从位置33,269解析为36,616,而不是1到33,616。我很困惑这是解析代码的一个问题,还是控制台要处理的行太多了?

public class ExcelReader {
public static final String SAMPLE_XLSX_FILE_PATH = "./LatLongPrice.xlsx";
public static void main(String[] args) throws IOException, InvalidFormatException {
Workbook workbook = WorkbookFactory.create(new File(SAMPLE_XLSX_FILE_PATH));
// Retrieving the number of sheets in the Workbook
System.out.println("Workbook has " + workbook.getNumberOfSheets() + " Sheets : ");
// obtain a sheetIterator and iterate over it
Iterator<Sheet> sheetIterator = workbook.sheetIterator();
System.out.println("Retrieving Sheets using Iterator");
while (sheetIterator.hasNext()) {
Sheet sheet = sheetIterator.next();
System.out.println("=> " + sheet.getSheetName());
}
// Getting the Sheet at index zero
Sheet sheet = workbook.getSheetAt(0);
// Create a DataFormatter to format and get each cell's value as String
DataFormatter dataFormatter = new DataFormatter();
// Obtain a rowIterator and columnIterator and iterate over them
System.out.println("\n\nIterating over Rows and Columns using Iterator\n");
Iterator<Row> rowIterator = sheet.rowIterator();
while (rowIterator.hasNext()) {
Row row = rowIterator.next();
// Iteratating over the columns of the current row
Iterator<Cell> cellIterator = row.cellIterator();
while (cellIterator.hasNext()) {
Cell cell = cellIterator.next();
String cellValue = dataFormatter.formatCellValue(cell);
System.out.print(cellValue + "\t");
}
System.out.println();
}
});
// Closing the workbook
workbook.close();
