Either use Integer.toHexString(), as suggested, or do something like
the following:

    System.out.print( Character.forDigit( b >> 4 & 0xf, 16) );
    System.out.println( Character.forDigit( b & 0xf, 16) );

The main advantage of doing it this way is that the above always prints
exactly 2 digits, whereas toHexString() will vary.

As someone else pointed out, these are two separate issues. Please
explain further.
