remainder=num%10;
sum=sum+remainder;
counter++;
if(counter==1){
strResult=String.valueOf(remainder);
}
else{
strResult=String.valueOf(remainder)+"+"+strResult;

Answer / gunreddy

Scanner scan = new Scanner(System.in);
int in = scan.nextInt();

String s = in + "";

int sum = 0;
int div = 10;
int di = 1;

for (int i = 0; i < s.length(); i++) {
int rem = in % div;
rem = rem / di;
sum += rem;
div *= 10;
di *= 10;

}
System.out.println("sum " + sum);
