Sep 10, 2017 · We will write three java programs to find factorial of a number. 1) using for loop 2) using while loop 3) finding factorial of a number entered by user. Before going through the program, lets understand what is factorial: Factorial of a number n is denoted as n! and the value of n! is: 1 * 2 * 3 * … (n-1) * n

In this section, we will create Java programs to find the factorial of a number using a while loop and do-while loop. How to find factorial? Then the factorial of 5 is represented as 5! Note: The value of 0! is 1, according to the convention for an empty product.

In this program, we've used for loop to loop through all numbers between 1 and the given number num (10), and the product of each number till num is stored in a variable factorial. We've used long instead of int to store large results of factorial.

Jan 27, 2025 · Here’s a step-by-step breakdown of the factorial program in Java using a while loop: Input a Number: The program prompts the user to enter a non-negative integer. Initialize Variables: Set up a variable to hold the result (factorial) and another for iteration (i). Use a While Loop: Multiply factorial by i repeatedly until the loop condition ...
