ArrayList<byte[]> to byte[][] in Java?

Question

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

Answer 1

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