A) Write a ‘java’ program to check whether given number is Armstrong or not. (Use static keyword)

 

 Slip 3 Q 1

SAVE CODE AS         "Armstrong.java"

import java.util.Scanner;

public class Slip3Q1 {
    static boolean is_armstrong(int n){
        int temp,last,digits=0,sum=0;
        temp = n;
        while (temp>0){
            temp=temp/10;
            digits++;
        }
        temp = n;
        while (temp>0){
            last = temp%10;
            sum+=Math.pow(last,digits);
            temp=temp/10;
        }
        return n == sum;
    }

    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);
        System.out.print("Enter a number to check armstrong : ");
        int number = scanner.nextInt();
        scanner.close();
        if (is_armstrong(number)){
            System.out.println(number+" is a armstrong number.");
        }
        else {
            System.out.println(number+" is not a armstrong number.");
        }
    }
}

OUTPUT :
