thank you so much , ur videos means a lot

Recursion would go as well public static long factorial(int number) { if(number>=1) return number*factorial(number-1); else return 1; } and SysOut factorial(5);

[@hemmishra1102]

//using while loop
import java.util.Scanner;
public class FactorialOfANumber {
public static void main(String[] args) {
System.out.println("Enter a number :");
Scanner sc=new Scanner(System.in);
int num;
num=sc.nextInt();
int number=num;
int res=1;
while (num>0)
{
res=res*num;
num--;
}
System.out.println("Factorial of "+number+" is: "+res);
}
}

very simple explanation...thaanks a lot sir

[@sdetpavan]

You are most welcome

[@RamisettyKalpana-jy7jb]

Thank you sir

Welcome

[@nickthelover1]

Good explanation. But did not cover while loop

[@kogilathotavijayreddy4963]

Find factorial of a big number using Big integer class..... because if we do using int for big numbers it will stack overflow

Wonderful ❤️

[@sdetpavan]

Thank you!

[@roshaniagrahari5640]

Very nice

[@gauri992]

Thankyou Sir

Could have explained recursive solution as well. Mostly interviewers look for that.

[@niteshwar1714]

public class Main
{
public static void main(String[] args) {
int num=5;
long fact=1;
while(num!=0){
for(int i=1;i

[@lekhyasagala]

Write your print out statement outside the while loop
