We can easily separate the digits of an integer number using Java.

public static void main(String[] args) {

int num=1020; // int number


while (num > 0) {

    System.out.println( num % 10);

    num = num / 10;

}

}

You can convert a number into String and then you can use toCharArray()  or split() method to separate the number into digits.
 

String number = String.valueOf(someInt);

char[] digits1 = number.toCharArray();
// or:
String[] digits2 = number.split("(?<=.)");

import java.util.*;

public class AmstrongNumber {

public static void main(String args[])

{

int a,i,count=0;

Scanner s= new Scanner(System.in);

System.out.println("Enter a number");

a=s.nextInt();

   while (a > 0) {

i= a % 10;

System.out.println(i);

  a = a / 10;

}

   //System.out.println(a);

}

}
