This example shows you Excel cell fills and colors using Apache POI.
In our example i have used all the possible colors and set it as Fills background colors of cells.
Below is the example code.
package com.java.connect.poi;import java.io.FileOutputStream;import java.io.IOException;import org.apache.poi.ss.usermodel.Cell;import org.apache.poi.ss.usermodel.CellStyle;import org.apache.poi.ss.usermodel.IndexedColors;import org.apache.poi.ss.usermodel.Row;import org.apache.poi.ss.usermodel.Sheet;import org.apache.poi.ss.usermodel.Workbook;import org.apache.poi.xssf.usermodel.XSSFWorkbook;public class POIFillAndColorExample {	public static void main(String[] args) throws IOException {		// Create a workbook object		Workbook workbook = new XSSFWorkbook();		// Create sheet		Sheet sheet = workbook.createSheet();		// Create a row and put some cells in it.

The generated excel files looks like below images.
