How to iterate excel cell in java
I have excel with 2 rows and 5 columns. Now I entered the code manually to take values from the 1st line. How can I repeat the process?
Below is the code for 1st line in excel. Starting from the second line, I don't know how to do this ... I want to repeat one line after another.
Workbook workbook = Workbook.getWorkbook(new File(
"\\C:\\users\\a-4935\\Desktop\\DataPool_CA.xls"));
Sheet sheet = workbook.getSheet("Sheet1");
System.out.println("Reached to Sheet");
Cell a = sheet.getCell(2,1);
Cell b = sheet.getCell(3,1);
Cell c = sheet.getCell(4,1);
Cell d = sheet.getCell(5,1);
Cell e = sheet.getCell(6,1);
Cell f = sheet.getCell(7,1);
Cell g = sheet.getCell(8,1);
Cell h = sheet.getCell(9,1);
Cell i = sheet.getCell(10,1);
String uId = a.getContents();
String deptFromDat = b.getContents();
String deptToDate = c.getContents();
String dept1 = d.getContents();
String arrival1 = e.getContents();
String eihon1 = f.getContents();
String branchCode1 = g.getContents();
String userType1 = h.getContents();
String sessionId1 = i.getContents();

Use the following code to iterate over all rows of the table:
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
}
}

You just need to change 1 to the line number and use a for loop. Based on your code, you can do the following for example. For exmaple:
for(int i=0; i<number; i++)
{
Cell a = sheet.getCell(2,i);
Cell b = sheet.getCell(3,i);
Cell c = sheet.getCell(4,i);
...
}
Or better yet, move the Cell declarations out of the for loop, which is best practice.
Cell a,b, c...;
for(int i=0; i<number; i++)
{
a = sheet.getCell(2,i);
b = sheet.getCell(3,i);
c = sheet.getCell(4,i);
...
}
