hii guys plz ans my question.write a program to input a number and check whether it is an an Armstrong number or not an Armstrong number is such a number whose sum of the cube of the digits is equal to the number for example 153 is an Armstrong number because one Cube + 5 Cube + 3 Cube is equals to 153 .

public class JavaExample {
public static void main(String[] args) {
int num = 370, number, temp, total = 0;
number = num;
while (number != 0)
{
temp = number % 10;
total = total + temp*temp*temp;
number /= 10;
}
if(total == num)
System.out.println(num + " is an Armstrong number");
else
System.out.println(num + " is not an Armstrong number");
}
}
CODE :
import java.util.*;
class armstrong
{
public static void main(String args[])
{
Scanner sc=new Scanner(System.in);
System.out.println("Enter a number");
int n=sc.nextInt();
int s=0;
int cpy=n;
while(n>0)
{
int d=n%10;
s=s+(d*d*d);
n=n/10;
}
if(s==cpy)
{
System.out.println("Armstrong number");
}
else
{
System.out.println("Not armstrong number");
}
}
}

Hope it helps :-)
