JAVA如何按空间拆分并存储为双数组

public class SplitArray {
    public static void main(String[] args) {
        int[] arr = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10};
        int splitSize = 3; // 拆分规则：每3个元素为一组

        int splitCount = (int) Math.ceil((double) arr.length / splitSize); // 计算拆分后的子数组数量

        int[][] splitArray = new int[splitCount][splitSize]; // 创建二维数组

        int index = 0;
        for (int i = 0; i < splitCount; i++) {
            for (int j = 0; j < splitSize; j++) {
                if (index < arr.length) {
                    splitArray[i][j] = arr[index]; // 将数据存储到二维数组中
                    index++;
                }
            }
        }

        // 打印拆分后的子数组
        for (int i = 0; i < splitCount; i++) {
            for (int j = 0; j < splitSize; j++) {
                System.out.print(splitArray[i][j] + " ");
            }
            System.out.println();
        }
    }
}
