如何使用Apache POI停止Java中的迭代

Question

I am reading a particular excel template in Java using Apache POI. There are some unwanted fields at the bottom (like a small guide) which I need to skip. So I want to stop the iteration whenever POI finds that a row is completely blank and hence the fields at the bottom will be skipped automatically.

I found many ways to handle a blank CELL but my requirement is for a complete row.

Answer 1

Following code will iterate through the cells of a row. it will keep a count for each cell it encounters(cellCount). another couont(nullCount), is incremented only if the cell is blank. if both these counts are equal, row is empty.

boolean isEmptyRow = false;
            int cellCount = 0;
            int nullCount = 0;

                Iterator<Cell> cellIterator = row.iterator();
                while (cellIterator.hasNext()) {
                    cellCount++;
                    Cell cell = (Cell) cellIterator.next();
                    if ((cell == null)
                            || ((cell != null) && (cell.getCellType() == Cell.CELL_TYPE_BLANK))) {
                        nullCount++;
                    }
                }

            if ((cellCount != 0) && (nullCount != 0)
                    && (cellCount == nullCount)) {        //If nullCount & cellCouont are same, Row is empty
                isEmptyRow = true;
            }
