Trying to solve what should be a simple problem. Got a list of Bytes, want to convert it at the end of a function to an array of bytes.
final List<Byte> pdu = new ArrayList<Byte>();
return pdu.toArray(new byte[pdu.size()]);;
The compiler doesn't like it, because
What you can do is use commons-lang's
Byte bytes = pdu.toArray(new Byte[pdu.size()]); return ArrayUtils.toPrimitive(bytes);
If you can't use commons-lang, simply loop through the array and fill another array of type
byte with the values (they will be automatically unboxed)
If you can live with
Byte instead of
byte - leave it that way.
