Java Program to Find Whether Given number is Armstrong or not

/*Write a program to find whether given no. is Armstrong or not.
  Example :
           Input - 153
           Output - 1^3 + 5^3 + 3^3 = 153, so it is Armstrong no. */

class Armstrong

        int num = Integer.parseInt(args[0]); 
        int n = num; //use to compare at If stmt
        int check=0,remainder;
        while(num > 0)
        {
            remainder = num % 10;
            check = check + (int)Math.pow(remainder,3);
            num = num / 10;
