Wie zu Lesen excel-Datei die ersten beiden Zeilen weglassen

Überspringen Sie die ersten zwei Zeilen mit rownum().Hier ist der Beispielcode

HSSFWorkbook      workBook = new HSSFWorkbook (fileSystem);
HSSFSheet         sheet    = workBook.getSheetAt (0);
Iterator<HSSFRow> rows     = sheet.rowIterator ();

while (rows.hasNext ())
{
  HSSFRow row = rows.next ();
  //display row number in the console.
  System.out.println ("Row No.: " + row.getRowNum ());
  if(row.getRowNum()==0 || row.getRowNum()==1){
   continue; //just skip the rows if row number is 0 or 1
  }
}

Hier ist das komplette Beispiel
