  //u can call this style method before loops where we are creating cells
   HSSFCellStyle yellowStyle = getYellowColoreBasedOnNewField(workBook);     

  private HSSFCellStyle getYellowColoreBasedOnNewField(HSSFWorkbook workBook) {
    HSSFCellStyle style = workBook.createCellStyle();
    HSSFFont font = createAndSetFontStyle(workBook);
    setYellowColor(style, font);
    return style;
} 

    private HSSFFont createAndSetFontStyle(HSSFWorkbook wb) {
    HSSFFont font = wb.createFont();
    font.setFontName(XSSFFont.DEFAULT_FONT_NAME);
    font.setFontHeightInPoints((short)10);
    return font;
}
