How to turn byte array into string array without any conversion

Question

I have a byte array. I need to show its bytes on screen. How can I turn the bytes into a string representation without any conversion?

*By conversion, in this context I mean not decoding it into ASCII or any other equivalent encoding system

So for instance, if I have:

byte[] a = { 0x3F, 0x2C, 0x6A };

I'd like results like this:

String[] b = { "3F", "2C", 6A"};

Answer 1

byte[] a = { 0x3F, 0x2C, 0x6A };
String[] s = new String[a.length];
for (int i=0; i<a.length; i++) {
  s[i] = String.format("%02X", a[i]);
}
// s => ["3F", "2C", "6A"]

Answer 2

Give this a try

Byte[] a = {31,22,62}; 

System.out.println(Arrays.deepToString(a));
