FAQs – Perfect Number Java Program Using For Loop
1. What is a Perfect Number in Java?
A Perfect Number is a positive integer that is equal to the sum of its proper divisors (excluding itself). For example, 28 is a Perfect Number because its divisors (1, 2, 4, 7, 14) add up to 28.
2. How do you write a Perfect Number Java Program using for loop?
You can write a Perfect Number program in Java by using a for loop to iterate through all numbers less than the given number and check if they are divisors. Then, add those divisors and compare the sum with the original number. If both are equal, it’s a Perfect Number.
3. Is this program important for Class 10, 11, and 12 ICSE/ISC/CBSE students?
Yes! The Perfect Number program is part of the Java programming curriculum for Classes 10, 11, and 12 in ICSE, ISC, and CBSE boards. It helps you understand the concept of loops, conditionals, and divisor logic, making it a common question in board exams.
Practice Question
Write a Java program using a for loop to display all the Perfect Numbers between 1 and 1000. This will help you strengthen your loop and conditional logic further.
