在Java中进一步拆分数组

int[] originalArray = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10};
int chunkSize = 3; // 每个子数组的大小

List<int[]> subArrays = new ArrayList<>();
int[] subArray = new int[chunkSize];

for (int i = 0; i < originalArray.length; i++) {
    subArray[i % chunkSize] = originalArray[i];
    
    if ((i + 1) % chunkSize == 0 || i == originalArray.length - 1) {
        subArrays.add(subArray);
        subArray = new int[chunkSize];
    }
}

// 输出拆分后的子数组
for (int[] arr : subArrays) {
    System.out.println(Arrays.toString(arr));
}

int[] originalArray = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10};
int chunkSize = 3; // 每个子数组的大小

List<int[]> subArrays = IntStream.range(0, originalArray.length)
        .boxed()
        .collect(Collectors.groupingBy(i -> i / chunkSize))
        .values()
        .stream()
        .map(list -> list.stream().mapToInt(i -> originalArray[i]).toArray())
        .collect(Collectors.toList());

// 输出拆分后的子数组
for (int[] arr : subArrays) {
    System.out.println(Arrays.toString(arr));
}
