How to print raw byte content from a byte[] array to stdout in Java?

Question

I am doing the same project as describe here:

Wrap deflated data in gzip format

My problem is that when I try to print out bytes, I get weird results. My pro

Answer 1

Assuming your byte array is called buf:

 System.out.println(Arrays.toString(buf));

Edit: It sounds like what you really want to do is write your bytes to stdout, not print them. See http://docs.oracle.com/javase/6/docs/api/java/io/PrintStream.html for the difference between printing to a stream and writing to it. Easiest way should be to call the write(byte[] b) method:

System.out.write(buf);

Answer 2

 /* There is an image / ic_launcher in the drawable folder for which I am making ByteArray   */



    Bitmap bmp = BitmapFactory.decodeResource(getResources(), R.drawable.img);
    ByteArrayOutputStream stream = new ByteArrayOutputStream();
    bmp.compress(Bitmap.CompressFormat.PNG, 100, stream);
    byte[] mByteArray = stream.toByteArray();

/* here I am showing the raw data not in hexadecimal format */

    System.out.println(Arrays.toString(mByteArray));

I think this will help you guys!
