Question

I have an ArrayList, which I want to divide into smaller Lists of n size, and perform an operation on each. My current method of doing this is

implemented with Array

Answer 1

// Testing data

List list = Arrays.asList(0, 1, 2,     3, 4, 5,    6, 7, 8,    9);
int n = 3;

// One line(statement) with java 8 stream and list.subList

List> partitions = IntStream.range(0, list.size())
    .filter(i -> i % n == 0)
    .mapToObj(i -> list.subList(i, Math.min(i + n, list.size() )))
    .collect(Collectors.toList());
