Answer 1

In case you are using JTable, refer to below code:

private int getColumnByName(JTable table, String name) {
    for (int i = 0; i < table.getColumnCount(); ++i)
        if (table.getColumnName(i).equals(name))
            return i;
    return -1;
}

Then you can use the following to set & get cell values :

table.setValueAt(value, rowIndex, getColumnByName(table, colName));

table.getValueAt(rowIndex, getColumnByName(table, colName));

If you are using POI, refer to below code:

InputStream inp = new FileInputStream("workbook.xls");

Workbook wb = WorkbookFactory.create(inp);
Sheet sheet = wb.getSheetAt(0);
Row row = sheet.getRow(2);
Cell cell = row.getCell(3);
if (cell == null)
    cell = row.createCell(3);
cell.setCellType(Cell.CELL_TYPE_STRING);
cell.setCellValue("a test");

// Write the output to a file
FileOutputStream fileOut = new FileOutputStream("workbook.xls");
wb.write(fileOut);
fileOut.close();

You can modify above code as per your requirement to get particular row and column.
