Program :
package SimpleQueries;
import java.util.Scanner;
public class ArmstrongNumberCheck {
void checkNumber(int number)
{
int sum=0;
int original=number;
while(number>0)
{
int a=number%10;
sum=sum+a*a*a;
number=number/10;
}
if(original==sum)
{
System.out.println("Number is armstrong");
}
else
System.out.println("Number is not armstrong");
}
public static void main(String[] args) {
System.out.println("Please enter a 3 digit number:");
int number = new Scanner(System.in).nextInt();
ArmstrongNumberCheck acheck= new ArmstrongNumberCheck();
acheck.checkNumber(number);
}
