There are some java classes that handle complex mathematical calculation BigDecimal BigInteger MathContex; https://docs.oracle.com/javase/7/docs/api/ But you can use Math class that is part of java.lang; so you don't need to import anything. There is a method called pow() and as parameters it takes two double values the first element is the base of the number and the secon element is the exponent of the base below I will post the code to calculate the cubic sum of this number 153 Hope this is the answer you are looking for. public class CubicSum{ public static void main(String [] args){ //this is the method Math.pow(135,3); //let's print it out System.out.println(Math.pow(135,3)); } } //keep in mind this method has more functions that this hope you understand

use string and the charAt methods solving this problem will be a some thing like that Scanner in =new Scanner(System.in); String n=in.next(); long number,sum=0; for(int i =0;i<n.length();i++) { number=Long.parseLong(n.charAt(i)+""); sum+=Math.pow(number,3); } System.out.println(sum);
