How do I create Anchor or link in iText?

This example show you how to use the com.itextpdf.text.Anchor class to create an external link in the PDF document. You can create an instance of Anchor with a phrase of string and set its reference, in this case a website URL, by calling the setReference() method of this object.

package org.kodejava.itextpdf;

import com.itextpdf.text.Anchor;
import com.itextpdf.text.Document;
import com.itextpdf.text.DocumentException;
import com.itextpdf.text.Paragraph;
import com.itextpdf.text.pdf.PdfWriter;

import java.io.FileNotFoundException;
import java.io.FileOutputStream;

public class AnchorDemo {
    public static void main(String[] args) {
        Document doc = new Document();
        try {
            PdfWriter.getInstance(doc, new FileOutputStream("AnchorDemo.pdf"));
            doc.open();

            String content = "You can learn Java programming on the " +
                    "following website: ";
            Paragraph paragraph = new Paragraph(content);

            // Creates a new anchor that link to external website
            // and add this anchor to the paragraph.
            Anchor anchor = new Anchor("Learn Java by Examples");
            anchor.setReference("https://kodejava.org");
            paragraph.add(anchor);

            doc.add(paragraph);
        } catch (DocumentException | FileNotFoundException e) {
            e.printStackTrace();
        } finally {
            doc.close();
        }
    }
}
