Write a ‘java’ program to check whether given number is Armstrong or not. (Use static keyword) | EasyCoding45

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

An Armstrong number (also known as a narcissistic number, pluperfect number, or pluperfect digital invariant) is a number that is the sum of its own digits each raised to the power of the number of digits. For example, 153 is an Armstrong number because $1^3+5^3+3^3=153$.

Here's a Java program that checks whether a given number is an Armstrong number or not using the static keyword:

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

import java.util.Scanner;

public class ArmstrongNumber1 {

    public static void main(String[] args) {

        Scanner scanner = new Scanner(System.in);

        System.out.print("Enter a number: ");

        int number = scanner.nextInt();

        if (isArmstrong(number)) {

            System.out.println(number + " is an Armstrong number.");

        } else {

            System.out.println(number + " is not an Armstrong number.");

        }

        scanner.close();

    }

    // Function to check whether a number is Armstrong or not

    private static boolean isArmstrong(int num) {

        int originalNumber, remainder, result = 0, n = 0;

        originalNumber = num;

        // Count the number of digits

        while (originalNumber != 0) {

            originalNumber /= 10;

            ++n;

        }

        originalNumber = num;

        // Calculate the sum of nth power of digits

        while (originalNumber != 0) {

            remainder = originalNumber % 10;

            result += Math.pow(remainder, n);

            originalNumber /= 10;

        }

        // Check if the result is equal to the original number

        return result == num;

    }

}

Note : This program defines a function isArmstrong to check whether a given number is an Armstrong number or not. The main method takes user input, calls the isArmstrong function, and prints the result.

Output :
