求解水仙花数

public class Sxh {

public static void main(String[] args) {
    while (true) {
    Scanner sc = new Scanner(System.in);
    String s = sc.next();
    int i = Integer.parseInt(s);
    int a = i / 100;//百位
    int b = (i - a * 100) / 10;//十位
    int c = (i - a * 100 - b * 10);//个位

    if (a * a * a + b * b * b + c * c * c == i) {
        System.out.println(i+"是水仙花数");
    }else{
        System.out.println(i+"不是水仙花数");
    }
    }

}
}
