在java中将列表拆分成多个列表

List<Integer> originalList = Arrays.asList(1, 2, 3, 4, 5, 6, 7, 8, 9, 10);
int batchSize = 3; // 每个子列表的大小

List<List<Integer>> splitLists = new ArrayList<>();
for (int i = 0; i < originalList.size(); i += batchSize) {
    int endIndex = Math.min(i + batchSize, originalList.size());
    splitLists.add(originalList.subList(i, endIndex));
}

System.out.println(splitLists);

List<Integer> originalList = Arrays.asList(1, 2, 3, 4, 5, 6, 7, 8, 9, 10);
int partitionSize = 3; // 每个子列表的大小

Map<Boolean, List<Integer>> partitionedLists = originalList.stream()
        .collect(Collectors.partitioningBy(i -> (originalList.indexOf(i) / partitionSize) % 2 == 0));

List<List<Integer>> splitLists = new ArrayList<>(partitionedLists.values());

System.out.println(splitLists);

import org.apache.commons.collections4.ListUtils;

List<Integer> originalList = Arrays.asList(1, 2, 3, 4, 5, 6, 7, 8, 9, 10);
int partitionSize = 3; // 每个子列表的大小

List<List<Integer>> splitLists = ListUtils.partition(originalList, partitionSize);

System.out.println(splitLists);
