Java中将一个列表拆分为多个较小列表的三种不同方法

import java.util.ArrayList;
import java.util.List;
public class Main {
    public static void main(String[] args) {
        List<Integer> list = new ArrayList<>();
        for (int i = 0; i < 10; i++) {
            list.add(i);
        }
        int chunkSize = 3;
        int numOfChunks = (int) Math.ceil((double) list.size() / chunkSize);
        List<List<Integer>> chunks = new ArrayList<>(numOfChunks);
        for (int i = 0; i < numOfChunks; i++) {
            int fromIndex = i * chunkSize;
            int toIndex = Math.min(fromIndex + chunkSize, list.size());
            chunks.add(list.subList(fromIndex, toIndex));
        }
        for (List<Integer> chunk : chunks) {
            System.out.println(chunk);
        }
    }
}

import java.util.List;
import java.util.stream.Collectors;
import java.util.stream.IntStream;
public class Main {
    public static void main(String[] args) {
        List<Integer> list = IntStream.range(0, 10).boxed().collect(Collectors.toList());
        int chunkSize = 3;
        List<List<Integer>> chunks = IntStream.range(0, (list.size() + chunkSize - 1) / chunkSize)
            .mapToObj(i -> list.subList(i * chunkSize, Math.min((i + 1) * chunkSize, list.size())))
            .collect(Collectors.toList());
        chunks.forEach(System.out::println);
    }
}

import com.google.common.collect.Lists;
import java.util.List;
public class Main {
    public static void main(String[] args) {
        List<Integer> list = Lists.newArrayList(0, 1, 2, 3, 4, 5, 6, 7, 8, 9);
        int chunkSize = 3;
        List<List<Integer>> chunks = Lists.partition(list, chunkSize);
        for (List<Integer> chunk : chunks) {
            System.out.println(chunk);
        }
    }
}
