The compiler doesn’t like it, because byte[]
isn’t Byte[]
.
What you can do is use commons-lang‘s ArrayUtils.toPrimitive(wrapperCollection)
:
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.
