converting an array of bytes to List<Byte>

Question

I could think of these things,

1. Arrays.asList(byte[]) converts byte[] to List<byte[]>,
2. looping through byte array and add each element to list

I was just wondering Is there any library function to do that?

Answer 1

Library Apache Commons Lang has ArrayUtils.toObject, which turns a primitive array to a typed object array:

int array[] = { 1, 2, 3 }; List<Integer> list = Arrays.asList(ArrayUtils.toObject(array)); 

Answer 2

As this post suggests: the guava Bytes class can help out:

byte[] bytes = ... List<Byte> byteList = Bytes.asList(bytes);
