Armstrong Number In Java Explained Step-by-Step | Master In Looping in Java

In this tutorial, we will learn how to check whether a number is an Armstrong Number in Java using a clear, step-by-step method. This video is specially designed for ICSE Class 10, ISC Class 11 & 12 Computer Science students, as well as B.Tech, BCA, MCA, CS, IT, and IIT-level students who want to strengthen their understanding of special number programs and improve their logical programming skills. An Armstrong Number (also known as a Narcissistic Number) is a number in which the sum of the powers of its digits (raised to the number of digits) is equal to the original number. For example, 153 is an Armstrong number because 1³ + 5³ + 3³ = 153. This program is widely used to demonstrate digit extraction, power calculations, and loop-based problem solving in Java. In this video, you will learn how to count the number of digits, extract digits using the modulus (%) operator, remove digits using integer division (/), compute the power of each digit, and calculate the sum of these powers. Finally, the program compares the calculated sum with the original number to determine whether it is an Armstrong Number. The tutorial includes clear logic explanation, complete Java program development, manual dry run, and output verification, making it suitable for beginners as well as intermediate learners. This program is frequently asked in ICSE and ISC board exams, university practical exams, coding assignments, and technical interviews, making it an essential topic for Java learners. 🎯 Topics Covered in This Video Introduction to Armstrong Number in Java Understanding the definition of Armstrong Number Counting the number of digits Digit extraction using modulus (%) operator Digit removal using division (/) operator Calculating the power of each digit Finding the sum of powers of digits Comparing the calculated sum with the original number Writing the complete Java program Performing a manual dry run of the program Understanding the program output Common mistakes in Armstrong Number programs Tips for solving special number problems 📚 Who Should Watch This Video This tutorial is ideal for: ICSE Class 10 Computer Applications students ISC Class 11 Computer Science students ISC Class 12 Computer Science students B.Tech Computer Science and IT students BCA and MCA students learning Java programming CS and IT diploma students IIT and engineering students studying programming fundamentals Beginners learning Java special number programs Students preparing for lab practical exams and viva 💡 Why Learn Armstrong Number Program?
