In the below example, we will create second cell of first row having applied style.

The code is given below :

import org.apache.poi.hssf.usermodel.*;
import org.apache.poi.hssf.util.HSSFColor;

import java.io.FileOutputStream;
import java.io.File;
import java.io.IOException;

public class ExcelCellFormat {
public static void main(String[] args) {
//
// Create an instance of workbook and sheet
//
HSSFWorkbook workbook = new HSSFWorkbook();
HSSFSheet sheet = workbook.createSheet();

//
// Create an instance of HSSFCellStyle which will be use to format the
// cell. Here we define the cell top and bottom border and we also
// define the background color.
//
HSSFCellStyle style = workbook.createCellStyle();
style.setBorderTop((short) 6); // double lines border
style.setBorderBottom((short) 1); // single line border
style.setFillBackgroundColor(HSSFColor.GREY_25_PERCENT.index);

//
// We also define the font that we are going to use for displaying the
// data of the cell. We set the font to ARIAL with 20pt in size and
// make it BOLD and give blue as the color.
//
HSSFFont font = workbook.createFont();
font.setFontName(HSSFFont.FONT_ARIAL);
font.setFontHeightInPoints((short) 20);
font.setBoldweight(HSSFFont.BOLDWEIGHT_BOLD);
font.setColor(HSSFColor.BLUE.index);
style.setFont(font);

//
// We create a simple cell, set its value and apply the cell style.
//
HSSFRow row = sheet.createRow(1);
HSSFCell cell = row.createCell(1);
cell.setCellValue(new HSSFRichTextString("Hi there... It's me again!"));
cell.setCellStyle(style);
sheet.autoSizeColumn((short) 1);

//
// Finally we write out the workbook into an excel file.
//
FileOutputStream fos = null;
try {
fos = new FileOutputStream(new File("xls/ExcelDemo.xls"));
workbook.write(fos);
} catch (IOException e) {
e.printStackTrace();
} finally {
if (fos != null) {
try {
fos.flush();
fos.close();
