How to do cell iteration of excel in java

Question

I am having an excel with 2 rows and 5 columns. Now I entered code manually to take values from 1st row. How can I iterate the process?

Below is the code for 1st row

Answer 1

Use the code below to iterate over all rows of a datasheet:

Sheet sheet = workbook.getSheet("Sheet1");
for (Row row : sheet) {
    for (Cell cell : row) {
        //your logic
    }
}

Or, alternatively, use the following code:

Sheet sheet = workbook.getSheet("Sheet1");
for (int i = 0; i < 2; i++) {
    Row row = sheet.getRow(i);
    if(row == null) {
        //do something with an empty row
        continue;
    }
    for (int j = 0; j < 5; j++) {
        Cell cell = row.getCell(j);
        if(cell == null) {
            //do something with an empty cell
            continue;
        }
        //your logic
    }
}
