Posted 2020-12-02 liehuonanjue

//存放的是电话号码包含的数字
int[] nums = {4, 2, 1, 0, 8, 3};
//电话号码出现的下标
int[] index = {2, 4, 5, 2, 3, 0, 3, 2, 1, 0, 0};
//方式1
for (int i = 0; i < index.length; i++) {
    System.out.print(nums[index[i]]);
}
System.out.println();
//方式2
for (int a : index) {
    System.out.print(nums[a]);
}
