加密数字

package com.Demo;

//加密数字
public class Test4 {
    public static void main(String[] args) {
        System.out.println(encry(1983));
    }
    //2.加密数字
    public static String encry(int nmber){
        int[] number=split(nmber);
        for (int i = 0; i < number.length; i++) {
            number[i]=(number[i]+5)%10;
        }
        reveres(number);
//4.遍历加密后的数字返回结果
        String data="";
        for (int i = 0; i < number.length; i++) {
            data+=number[i];
        }
        return data;
    }
//3.反转数字
    public static void reveres(int[] number) {
        for (int i = 0,j=number.length-1; i<j;i++,j--) {
            int type=number[j];
            number[j]=number[i];
            number[i]=type;

        }
    }
//1.解析成一个一个的数字
    public static int[] split(int nmber) {
        int[] number=new int[4];
        number[0]=nmber/1000;
        number[1]=(nmber/100)%10;
        number[2]=(nmber/10)%10;
        number[3]=nmber%10;
        return number;
    }
