I have a method that returns ArrayList<byte[]> and now I want to know if there is a way I can convert it in byte[][]. I've seen so many questions about ArrayList<byte>, but not ArrayList<byte[]>. Can I do that somehow?

ArrayList<byte[]> list = new ArrayList<>()

to

byte [][] b

    You use the same technique to convert an `Arraylist` to `X[]`, no matter what `X` is. Even if you need to use `[]` to write out `X` properly. – Karl Knechtel Nov 12 '21 at 14:06

list.toArray(new byte[0][]) or list.stream().toArray(byte[][]::new)
