定义功能，将数组中的0元素，使用1-10之间的随机数替换掉。

public static void main(String[] args) {
int[] arr = {1, 43, 43, 5, 4, 6, 6, 7, 7, 88, 9, 9, 9, 0, 0, 9};
for (int i = 0; i < arr.length; i++) {
Random r = new Random();
int random = r.nextInt(10) + 1;
if (arr[i] == 0) {
arr[i] = random;
}

System.out.println(arr[i]);
}
}
