java对一个number进行倒置

//对一个number进行倒置public class NumberInversion2 {public static void main(String[] args) {int num = 123456;int numbk = 0;int plus = 100000;for(int i=0; i < 6; i++){numbk += plus*(num%10);plus = plus/10;num = num/10;}System.out.println(numbk);}}

另附网友的另一种算法

public class NumberC {    public static void main(String[] args) {        int num = 123456;        char[] numx = String.valueOf(num).toCharArray();        for(int i=0; i<numx.length/2; i++) {            if(i != numx.length-1-i) {                char temp = numx[i];                numx[i] = numx[numx.length-1-i];                numx[numx.length-1-i] = temp;            }        }        for (char str : numx) {            System.out.println(str);        }    }}
