Create a arraylist of bytes by a inputstream

Question

I want to get a inputStream source from a file, and put this as a Byte in a ArrayList.

But I didn´t find any thing about this.

Can someone help me?

 byte[] bytes = Files.readAllBytes(path);

The conversion to a List<Byte>, if you really need it, can be done with a simple loop.

Might be worth adding a note about Arrays.asList(Files.readAllBytes(path)) since he wants an ArrayList.

That would return a List<byte[]> with one element.

But I want the inputStream, because its a file from in e-mail.
