  15. for (int i = 0; i < cells.length; i++) {

  16. cells[i] = rows[i].createCell(1);

  17. cells[i].setCellValue(1111.25);

  18.  

  19. cells[i].setCellStyle(styles[i]);

  20. }

Row[] rows = new Row[2];
for (int i = 0; i < rows.length; i++) {

}
DataFormat format = wb.createDataFormat();

CellStyle[] styles = new CellStyle[2];
for (int i = 0; i < styles.length; i++) {
    styles[i] = wb.createCellStyle();
}
styles[0].setDataFormat(format.getFormat("0.0"));
styles[1].setDataFormat(format.getFormat("#,##0.000"));

Cell[] cells = new Cell[2];
for (int i = 0; i < cells.length; i++)  {

  8.  

  9. cell1_1.setCellValue(30);

  10. cell1_2.setCellValue(25);

  11. cell1_3.setCellFormula("B2+C2");

  12. cell2_3.setCellFormula("MOD(B2,C2)");

Row row1 = wb.getSheet("sheetname13").createRow(1);
Row row2 = wb.getSheet("sheetname13").createRow(2);

Cell cell1_1 = row1.createCell(1);
Cell cell1_2 = row1.createCell(2);
Cell cell1_3 = row1.createCell(3);
Cell cell2_3 = row2.createCell(3);

cell1_1.setCellValue(30);
cell1_2.setCellValue(25);
cell1_3.setCellFormula("B2+C2");
cell2_3.setCellFormula("MOD(B2,C2)");
