Java Programing laungage

In this example we will learn how we can create PDF using java. In this example we are creating very first example of HelloWord.In this we are creating an PDF file and adding Paragraph into this pdf. To create a PDF using java you need iText API.Which you can download from website.This is an open source jar .Then you have to set class path of this Text jar. In this example we are simply creating PDF file with name of "HelloWorld.pdf".We are writing HelloWorld in this PDF file.

There are basic five steps to create PDF:

Step1: Creation of a document-object

Document document = new Document();

Step2: Create a writer that listens to the document and directs a PDF-stream to a file.

PdfWriter.getInstance(document, new FileOutputStream("HelloWorld.pdf"));

Step3: Open the document

document.open();

Step4: Add a paragraph to the document

document.add(new Paragraph("Hello World"));

Step5: Close the document

document.close();

Example:

package com.itext.pdf.example.r4r;

/In this example we are making a simple first program of pdf.
/We are creating a pdf with name "HelloWorld.pdf".
/In this pDF we are writeing a String "HelloWorld" .
/You can compile and run this application at command promt.
/To run this example you need only iText API and set its classpath. 
/There are following five steps to create PDF using java.

import java.io.FileOutputStream;
import java.io.IOException;
import com.lowagie.text.Document;
import com.lowagie.text.DocumentException;
import com.lowagie.text.Paragraph;
import com.lowagie.text.pdf.PdfWriter;

public class HelloWorld 
	{
/*** Generates a PDF file with the text 'Hello World' */
	
public static void main(String[] args) 
	{
System.out.println("Hello World");

/ Step1: Creation of a document-object
Document document = new Document();
try {

/ Step2:Create a writer that listens to 
/the document and directs a  PDF-stream to a file.
PdfWriter.getInstance(document, new FileOutputStream(
"HelloWorld.pdf"));

/ Step3: Open the document
document.open();

/ Step4: Add a paragraph to the document
document.add(new Paragraph("Hello World"));
} 
catch (DocumentException de) 
	{
System.err.println(de.getMessage());
     } 
catch (IOException ioe) 
	{
System.err.println(ioe.getMessage());
    }

/ Step 5: Close the document
document.close();
System.out.println("PDF is created sussecefully ");
	}
}
