I want to print all the rows and column in my excel, but it always print the last column alone(ie whatever writes in the last loop).
Is there a way to get print all the values and not overwrite the excel again and again. below is the program i used please let me know where i have mistaken.
I want the 1st Column get printed first and then the 2nd column. Don't want the row to get print first
public class test {
public static void main(String[] args) throws IOException, Exception {
XSSFWorkbook wb=new XSSFWorkbook();
XSSFSheet spreadsheet=wb.createSheet();
FileOutputStream fos=null;
for(int j=0; j<4; j++) {
for(int i=0; i<10; i++) {
Row row=spreadsheet.createRow(i);
Cell value=row.createCell(j);
value.setCellValue(i+" Test");
fos=new FileOutputStream("Testexcel.xlsx");
wb.write(fos);
}
}
wb.close();
fos.close();
}
}
Look at the comments as well.
public static void main(String[] args) throws IOException {
XSSFWorkbook wb = new XSSFWorkbook();
XSSFSheet spreadsheet = wb.createSheet();
FileOutputStream fos = null;
for (int row = 0; row < 10; row++) {
XSSFRow xssfRow = spreadsheet.createRow(row); // row should be created only once per iteration
for (int col = 0; col < 4; col++) {
XSSFCell value = xssfRow.createCell(col);
value.setCellValue(row + " Test"); // changes as per your need
// value.setCellValue("("+ row + "," + col + ") Test");
}
}
fos = new FileOutputStream("Testexcel.xlsx"); // this should be done at the end, not within the loop
wb.write(fos);
wb.close();
fos.close();
}
please try this code
public class test {
public static void main(String[] args) throws IOException, Exception {
XSSFWorkbook wb=new XSSFWorkbook();
XSSFSheet spreadsheet=wb.createSheet();
FileOutputStream fos=null;
for(int i=0; i<10; i++) {
Row row=spreadsheet.createRow(i);
for(int j=0; j<4; j++) {
Cell value=row.createCell(j);
value.setCellValue(i+" Test");
}
}
fos=new FileOutputStream("Testexcel.xlsx");
wb.write(fos);
wb.close();
fos.close();
}
}
ok for you case try this and get back to me i cant test this. cause i don't have the source code.
public class test {
public static void main(String[] args) throws IOException, Exception {
XSSFWorkbook wb=new XSSFWorkbook();
XSSFSheet spreadsheet=wb.createSheet();
FileOutputStream fos=null;
for(int i=0; i<10; i++) {
Row row=spreadsheet.createRow(i);
}
for(int j=0; j<4; j++) {
for(int i=0; i<10;i++){
Row row = spreadsheet.getRow(i);
Cell value=row.createCell(j);
value.setCellValue(i+" Test");
}
}
fos=new FileOutputStream("Testexcel.xlsx");
wb.write(fos);
wb.close();
fos.close();
}
}
