Help me with this thing.

Question

Why does this if () condition is not working when we enter input as 371 ??

import java.util.Scanner;
class armStrong{
public static void main(String []args){
Scanner sc=new Scanner(System.in);
int num,arm=0,a;
System.out.println("Enter the num which you want to check which is < 1000= ");
num=sc.nextInt();

while(num!=0){
a=num%10;
arm=arm+(a*a*a);
num=num/10;
}
System.out.println(arm);

if(arm==num){
System.out.println("The integer is an Armstrong number.");
}
else{
System.out.println("The integer is not an Armstrong number.");
}

}
}

Answer 1

Because the value of num is lost in the while loop. Store the value of the num in a variable before the loop and check arm with that variable
