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 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.

Apr 7, 2025 · The factorial of a non-negative integer is multiplication of all integers smaller than or equal to n. In this article, we will learn how to write a program for the factorial of a number in Java. Formulae for Factorial. n! = n * (n-1) * (n-2) * (n-3) * …….. * 1

Dec 29, 2017 · String a = “”; for(i = 1; i <= num; i++) { factorial = factorial.multiply(i); if(i==1) a = String.valueOf(i) else a = a + "*" + String.valueOf(i) } System.out.println("!"+num+"="+ a + "="+factorial);

Aug 29, 2015 · public class forLoop1{ public static void main(String[] args){ // n is the number whose factorial is to be calculated int n = 10; int factorial = 1; for(int i = n; i >= 2; i--){ factorial = factorial * i; } System.out.println(factorial); } }

Nov 13, 2024 · Given the number n (n >=0), find its factorial. Factorial of n is defined as 1 x 2 x … x n. For n = 0, factorial is 1. We are going to discuss iterative and recursive programs in this post. Examples: The idea is simple, we initialize result as 1. Then run a loop from 1 to n and multiply every number with n.

Write a Java Program to find the Factorial of a number using For Loop, While Loop, Functions, and Recursion. The Factorial of a number is the product of all the numbers less than or equal to that number & greater than 0.

Sep 20, 2013 · You should make a public static int factorial(int n) function which just computes the factorial of its argument n; also googling for factorial java gives interesting results. –

In Java Programming, we can write a program in the following ways. 1.) Factorial of a Number using For Loop. 2.) Factorial Program using While Loop. 3.) Factorial Program using Do-While Loop. 4.) Find Factorial of a number using recursion in java. 5.) Find Factorial of a number entered by the user in java.

Mar 11, 2024 · In this article we will show you the solution of factorial program in java using for loop, a number's factor is represented by the symbol n! and is defined as the sum of all positive descending integers. Just follow the step by step guide below.
