How do I change the Text Color and the Fillcolor

Question

How do I change the header font color to white and the fill green? These are the classes that I am using:

import static org.apache.poi.ss.usermodel.CellStyl

If you want to set the color as simple cellstyle... you can write code like.

 cell.setCellValue("Header Text");
 XSSFCellStyle headerStyle = wb.createCellStyle();
 Font headerFont = wb.createFont();
 headerStyle.setFillForegroundColor(IndexedColors.GREEN.getIndex());
 headerFont.setColor(IndexedColors.WHITE.getIndex());
 headerStyle.setFillPattern(CellStyle.SOLID_FOREGROUND);
 headerStyle.setFont(headerFont);
 cell.setCellStyle(headerStyle);

This will fill the cell with GREEN color and the font will be of Bold WHITE color
