Answer 1

This worked for me. I haven't used any third-party libraries. Just the ones that are shipped with Java.

import java.io.*;
import java.nio.file.Files;
import java.nio.file.Path;
import java.nio.file.Paths;

public class PDFUtility {

public static void main(String[] args) throws IOException {
    /**
     * Converts byte stream into PDF.
     */
    PDFUtility pdfUtility = new PDFUtility();
    byte[] byteStreamPDF = pdfUtility.convertPDFtoByteStream();
    FileOutputStream fileOutputStream = new FileOutputStream("C:\\Users\\aseem\\Desktop\\BlaFolder\\BlaFolder2\\aseempdf.pdf");
    fileOutputStream.write(byteStreamPDF);
    fileOutputStream.close();
    System.out.println("File written successfully");
}

/**
 * Creates PDF to Byte Stream
 *
 * @return
 * @throws IOException
 */
protected byte[] convertPDFtoByteStream() throws IOException {
    Path path = Paths.get("C:\\Users\\aseem\\aaa.pdf");
    return Files.readAllBytes(path);
}

}
