1. iText – Write PDF
iText PdfWriter example to write content to a PDF file.
package com.mkyong;
import com.itextpdf.text.*;
import com.itextpdf.text.pdf.PdfWriter;
import java.io.File;
import java.io.FileNotFoundException;
import java.io.FileOutputStream;
import java.io.IOException;
public class PdfWriteExample {
private static final String FILE_NAME = "/tmp/itext.pdf";
public static void main(String[] args) {
writeUsingIText();
}
private static void writeUsingIText() {
Document document = new Document();
try {
PdfWriter.getInstance(document, new FileOutputStream(new File(FILE_NAME)));
//open
document.open();
Paragraph p = new Paragraph();
p.add("This is my paragraph 1");
p.setAlignment(Element.ALIGN_CENTER);
document.add(p);
Paragraph p2 = new Paragraph();
p2.add("This is my paragraph 2"); //no alignment
document.add(p2);
Font f = new Font();
f.setStyle(Font.BOLD);
f.setSize(8);
document.add(new Paragraph("This is my paragraph 3", f));
//close
document.close();
System.out.println("Done");
} catch (FileNotFoundException | DocumentException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}
}
Output, a new PDF file is created – /tmp/itext.pdf
2. iText – Read PDF

public class PdfReadExample {
private static final String FILE_NAME = "/tmp/itext.pdf";
public static void main(String[] args) {
PdfReader reader;
try {
reader = new PdfReader("f:/itext.pdf");
// pageNumber = 1
String textFromPage = PdfTextExtractor.getTextFromPage(reader, 1);
System.out.println(textFromPage);

3. Talk
The code above uses 2 major classes – PdfWriter and PdfReader. As indicated by the name, these classes provide the base for reading and writing a pdf. Document object is basically a Pdf file which is being addressed. Paragraph is a content type that can be written to the Pdf. Other possible content types include Anchor, Chapter, Section, List, PdfPTable etc. All these classes help to create a specific type of content as per the requirement in the pdf.
iText pdf is the most convenient library with its latest version supporting HTML to Pdf, Image to Pdf as well as QR codes. The only drawback of the iText pdf library is that it is complex to work with it. The class structure is tough to understand.
