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;
