java itext document

Document represents current pdf document to which we are adding content. It is represented by com.itextpdf.text.Document class.

Steps:

1. Create Document instance. It represents the current document to which we are adding content.
2. Create OutputStream instance. It represents the generated pdf.
3. Create PDFWriter instance and pass Document and OutputStream instance to its constructor.
4. Open the Document by calling document.open().
5. Add the content to the document by calling document.add() method.
6. Close the document by calling document.close() method.

Example:

PDFCreateExample.java

import java.io.File;
import java.io.FileOutputStream;
import java.io.OutputStream;
import com.itextpdf.text.Document;
import com.itextpdf.text.Paragraph;
import com.itextpdf.text.pdf.PdfWriter;
 
/**

public class PDFCreateExample {
  public static void main(String args[]){
    try {
        //Create Document instance.
 Document document = new Document();
 
 //Create OutputStream instance.
 OutputStream outputStream = 
  new FileOutputStream(new File("D:\\TestFile.pdf"));
 
 //Create PDFWriter instance.
        PdfWriter.getInstance(document, outputStream);
 
        //Open the document.
        document.open();
 
        //Add content to the document.
        document.add(new Paragraph("Hello world, " +
        "this is a test pdf file."));
 
        //Close document and outputStream.
        document.close();
        outputStream.close();
 
        System.out.println("Pdf created successfully.");
    } catch (Exception e) {
 e.printStackTrace();
    }
  }
}
