byte[] to file

[Dave Comeau]

Hi,
I have a byte[] that contains binary image data (for pngs and gifs). I can't figure out how to write this data to a file.
Can anyone give me an overview of what I need to do?
Thanks!

FileOutputStream f = new FileOutputStream("pic.gif");
for(int i = 0; i < <size of ur byte array>; i++)
f.write(<ur byte array name>[i]);
f.close();
i think this should do it.

No need for a loop - just spit out the whole array at once:

  public static void toFile(byte[] array, String fileName) throws IOException
  {
    OutputStream out = new BufferedOutputStream(FileOutputStream(fileName));
    out.write(array);
    out.close();
  }

The BufferedOutputStream is optional, but a good idea in general for efficiency.
