Java代码到底是哪里出错呀，代码甚至连整数都输出不出来

Question

mport java.util.Scanner;
public class LITI {
    public static void main(String[] args){
        Scanner scanner=new Scanner(System.in);
        int n= scanner.nextInt();
        int ones =n%10;
        int tens = (n/10)%10;
        int hundreds = (n/100)%10;
        int thousands = n/1000;
        int onescube=ones*ones*ones;
        int tenschbe=tens*tens*tens;
        int hundredscube=hundreds*hundreds*hundreds;
        int thousandscube=thousands*thousands*thousands;
        int sum=onescube+tenschbe+hundredscube+thousandscube;
        System.out.println("sum");
    }
}

为什么输入1234，想求出各个数位上的数的立方和100，却输出2253.20呀

他们都是人机别问了

你试试我这个

import java.util.Scanner;

public class LITI {
    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);
        int n = scanner.nextInt();
        int ones = n % 10;
        int tens = (n / 10) % 10;
        int hundreds = (n / 100) % 10;
        int thousands = n / 1000;
        int onesCube = ones * ones * ones;
        int tensCube = tens * tens * tens;
        int hundredsCube = hundreds * hundreds * hundreds;
        int thousandsCube = thousands * thousands * thousands;
        int sum = onesCube + tensCube + hundredsCube + thousandsCube;
        System.out.println(sum);
    }
}
