PDF to byte array and vice versa

Question

I need to convert pdf to byte array and vice versa.

Can any one help me?

This is how I am converting to byte array

public static byte[] conve         


        

Answer 1

Java 7 introduced Files.readAllBytes(), which can read a PDF into a byte[] like so:

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

Path pdfPath = Paths.get("/path/to/file.pdf");
byte[] pdf = Files.readAllBytes(pdfPath);

EDIT:

Thanks Farooque for pointing out: this will work for reading any kind of file, not just PDFs. All files are ultimately just a bunch of bytes, and as such can be read into a byte[].
