Apache POI - 如何在特定单元格启动我的 cellIterator？

Question

I guess answering the question, how to start an Iterator from a specific index, would help me in figuring out how to begin my cellIterator from a specific cell? I've dropped my code block below:

    Iterator<Row> rowIterator = spreadSheet.iterator();
            while(rowIterator.hasNext()) {
                row = (XSSFRow) rowIterator.next();
                Iterator<Cell> cellIterator = row.cellIterator();
                //Cell cell = row.getCell(7);
                cell = cellIterator.next();

How do I get my iterator to start at column (cell) 7?

Any help is greatly appreciated: Thanks :)

LinkedList has a method listIterator(int) which starts from a particular index. I doubt whether rowIterator or columnIteratr provides this. But you can use something like:

public Iterator<E> iterator(int index) {
    Iterator<E> iterator = iterator();
    for (int i = 0; i < index && iterator.hasNext(); i++) {
        iterator.next();
    }
    return iterator;
}
