java生成6位随机数代码片段，java6位随机数片段,int[] array

int[] array = {0,1,2,3,4,5,6,7,8,9};Random rand = new Random();for (int i = 10; i > 1; i--) {    int index = rand.nextInt(i);    int tmp = array[index];    array[index] = array[i - 1];    array[i - 1] = tmp;}int result = 0;for(int i = 0; i < 6; i++)    result = result * 10 + array[i];System.out.println(result);
