I'm looking for a cell in a spreadsheet that has the string 'Total' and then use the row in which that cell is to find the total value in another cell which is always the same cell/column (the 10th cell in a 0 based index).
I have the following code, which has no errors (syntax), but the findCell method is not returning rowNum value:
public static void main(String[] args) throws IOException{
String fileName = "C:\\file-path\\report.xls";
String cellContent = "Total";
int rownr=0, colnr = 10;
InputStream input = new FileInputStream(fileName);
HSSFWorkbook wb = new HSSFWorkbook(input);
HSSFSheet sheet = wb.getSheetAt(0);
rownr = findRow(sheet, cellContent);
output(sheet, rownr, colnr);
finish();
}
private static void output(HSSFSheet sheet, int rownr, int colnr) {
/*
* This method displays the total value of the month
*/
HSSFRow row = sheet.getRow(rownr);
HSSFCell cell = row.getCell(colnr);
System.out.println("Your total is: " + cell);
}
private static int findRow(HSSFSheet sheet, String cellContent){
/*
* This is the method to find the row number
*/
int rowNum = 0;
for(Row row : sheet) {
for(Cell cell : row) {
while(cell.getCellType() == Cell.CELL_TYPE_STRING){
if(cell.getRichStringCellValue().getString () == cellContent);{
rowNum = row.getRowNum();
return rowNum;
}
}
}
}
return rowNum;
}
private static void finish() {
System.exit(0);
}
}
This method fix is the solution to your problem:
private static int findRow(HSSFSheet sheet, String cellContent) {
for (Row row : sheet) {
for (Cell cell : row) {
if (cell.getCellType() == Cell.CELL_TYPE_STRING) {
if (cell.getRichStringCellValue().getString().trim().equals(cellContent)) {
return row.getRowNum();
}
}
}
}
return 0;
}
Keep in mind that your colnr
is still a fixed value.
