Apache POI Word - Font & Alignment

This chapter shows how to apply different font styles and alignments in a Word document using Java. Generally, Font Style contains: Font size, Type, Bold, Italic, and Underline. And Alignment is categorized into left, center, right, and justify.

Font Style

The following code is used to set different styles of font −

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

import org.apache.poi.xwpf.usermodel.VerticalAlign;
import org.apache.poi.xwpf.usermodel.XWPFDocument;
import org.apache.poi.xwpf.usermodel.XWPFParagraph;
import org.apache.poi.xwpf.usermodel.XWPFRun;

public class FontStyle {

   public static void main(String[] args)throws Exception {

      //Blank Document
      XWPFDocument document = new XWPFDocument(); 
        
      //Write the Document in file system
      FileOutputStream out = new FileOutputStream(new File("fontstyle.docx"));
        
      //create paragraph
      XWPFParagraph paragraph = document.createParagraph();
        
      //Set Bold an Italic
      XWPFRun paragraphOneRunOne = paragraph.createRun();
      paragraphOneRunOne.setBold(true);
      paragraphOneRunOne.setItalic(true);
      paragraphOneRunOne.setText("Font Style");
      paragraphOneRunOne.addBreak();
        
      //Set text Position
      XWPFRun paragraphOneRunTwo = paragraph.createRun();
      paragraphOneRunTwo.setText("Font Style two");
      paragraphOneRunTwo.setTextPosition(100);
 
      //Set Strike through and Font Size and Subscript
      XWPFRun paragraphOneRunThree = paragraph.createRun();
      paragraphOneRunThree.setStrike(true);
      paragraphOneRunThree.setFontSize(20);
      paragraphOneRunThree.setSubscript(VerticalAlign.SUBSCRIPT);
      paragraphOneRunThree.setText(" Different Font Styles");
        
      document.write(out);
      out.close();
      System.out.println("fontstyle.docx written successully");
   }
}

Save the above code as FontStyle.java and then compile and execute it from the command prompt as follows −

$javac FontStyle.java
$java FontStyle

It will generate a Word file named fontstyle.docx in your current directory and display the following output on the command prompt −

fontstyle.docx written successfully

The fontstyle.docx file looks as follows.

Alignment

The following code is used to set alignment to the paragraph text −

import java.io.File;
import java.io.FileOutputStream;
import org.apache.poi.xwpf.usermodel.ParagraphAlignment;
import org.apache.poi.xwpf.usermodel.XWPFDocument;
import org.apache.poi.xwpf.usermodel.XWPFParagraph;
import org.apache.poi.xwpf.usermodel.XWPFRun;

public class AlignParagraph {

   public static void main(String[] args)throws Exception {

      //Blank Document
      XWPFDocument document = new XWPFDocument(); 
        
      //Write the Document in file system
      FileOutputStream out = new FileOutputStream(
      new File("alignparagraph.docx"));
        
      //create paragraph
      XWPFParagraph paragraph = document.createParagraph();
        
      //Set alignment paragraph to RIGHT
      paragraph.setAlignment(ParagraphAlignment.RIGHT);
      XWPFRun run = paragraph.createRun();
      run.setText("At howcodex.com, we strive hard to " +
         "provide quality tutorials for self-learning " +
         "purpose in the domains of Academics, Information " +
         "Technology, Management and Computer Programming " +
         "Languages.");
        
      //Create Another paragraph
      paragraph = document.createParagraph();
        
      //Set alignment paragraph to CENTER
      paragraph.setAlignment(ParagraphAlignment.CENTER);
      run = paragraph.createRun();
      run.setText("The endeavour started by Mohtashim, an AMU " +
         "alumni, who is the founder and the managing director " +
         "of Howcodex (I) Pvt. Ltd. He came up with the " +
         "website howcodex.com in year 2006 with the help" +
         "of handpicked freelancers, with an array of tutorials" +
         " for computer programming languages. ");
			
      document.write(out);
      out.close();
      System.out.println("alignparagraph.docx written successfully");
   }
}

Save the above code as AlignParagraph.java and then compile and execute it from the command prompt as follows −

$javac AlignParagraph.java
$java AlignParagraph

It will generate a Word file named alignparagraph.docx in your current directory and display the following output in the command prompt −

alignparagraph.docx written successfully

The alignparagraph.docx file looks as follows −
