听说最近流行这样玩手机号

package com.chauvet.utils;

public class Test1 {
    public static void main(String[] args) {
        int[] arr = new int[]{8,5,1,3,6,4};
        int[] index = new int[]{2,0,1,2,5,1,3,2,4,5,2};
        String tel = "";
        for (int i : index) {
            tel += arr[i];
        }
        System.out.println("my tel:"+tel);
    }
}
