            System.out
                    .println("byteArray of \"Hi\" with charsetName \"ISO-8859-1\" = "
                            + byteArray);
            for (byte b : byteArray)
            {
                System.out.println(b);
            }
        }
        catch (UnsupportedEncodingException e)
        {
            e.printStackTrace();
        }

    }
}

Output

byteArray of "Hi" with charsetName "UTF-8" = [B@1a93a7ca
72

--------------------
byteArray of "Hi" with charsetName "ISO-8859-1" = [B@66cd51c3
