Perfect 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 a Perfect Number in Java using a clear and 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 mathematical and number-based Java programs and improve their logical programming skills. A Perfect Number is a number in which the sum of its proper factors (excluding the number itself) is equal to the number. For example, 6 is a perfect number because its factors 1, 2, and 3 add up to 6. This program is widely used to demonstrate factor finding, looping logic, and conditional checking in Java programming. In this video, you will learn how to find the factors of a number, calculate the sum of proper factors, and compare the result with the original number to determine whether it is a Perfect Number. The tutorial includes clear explanation of logic, 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 Perfect Number in Java Understanding the definition of Perfect Number Finding proper factors of a number Using loops to check divisibility Applying modulus (%) operator Calculating the sum of proper factors Comparing the sum with the original number Writing the complete Java program Performing a manual dry run Understanding the program output Common mistakes in Perfect Number programs Tips for solving factor-based 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 mathematical programs Students preparing for lab practical exams and viva 💡 Why Learn Perfect Number Program?
