I am waiting for your valuable suggestion to make necessary alteration in code ByteArrayToString2b.java to generating test_out1.pdf containing 'Hello World', Please help me.

I am very much thankful to you for your valuable suggestion. After observing your suggested example [https://www.tutorialspoint.com/itext/itext_adding_paragraph.htm] I altered my code, now there is no compilation error, But when I am executing the code it is generating test_out1.pdf containing with the Byte Array. As per my requirement the test_out1.pdf file containing 'Hello World' is not generating. My requirement is that the java code ByteArrayToString2b.java should generate test_out1.pdf file containing 'Hello World'. Like test_out.pdf file which I generated through the java code ByteArrayToString2a.java output file test_out.pdf which I informed you earlier.

Moreover it is observed that the statement
String str = new String(bytearray);
above statement I used both the java code ByteArrayToString2a.java and ByteArrayToString2b.java, but it is only performing in java code ByteArrayToString2a.java at the time of execution.

Following is my Altered Java Code at present :

import java.io.File;
import java.io.IOException;
import java.nio.file.Files;
import java.nio.file.Path;
import java.io.File;
import java.io.FileInputStream;
import java.io.FileWriter;

import com.itextpdf.text.pdf.PdfWriter;


public class ByteArrayToString2b {
public static void main(String[] args) throws IOException {

String fileName = "d:\\sumit\\test3\\file4.txt";
File file = new File(fileName);
Document document = new Document();

try {
PdfWriter writer = PdfWriter.getInstance(document, new
FileOutputStream("D:/sumit/test3/test_out1.pdf"));
document.open();
byte [] bytearray = Files.readAllBytes(file.toPath());
String str = new String(bytearray);
Paragraph para = new Paragraph (str);
document.add(para);
document.close();
}

catch (DocumentException exception)
{
exception.printStackTrace();
}
catch (FileNotFoundException exception)
{
exception.printStackTrace();
}


}
}

Which is not generating test_out1.pdf containing 'Hello World', Please help me.
