Java Program to Find Factorial of a Number using FOR LOOP
In this tutorial we will write a Java program to find the factorial of a number using for loop. Factorial of a number is given as –
n! = n*(n-1)! till 1.
E.g. 4! = 4 x 3 x 2 x 1
5! = 5 x 4 x 3 x 2 x 1
6! = 5 x 5 x 4 x 3 x 2 x 1
We will be using For Loop to find the factorial in this program.
Java program to Find Factorial of a Number –
public class JavaApplication4 { public static void main(String[] args) { int num = 4; int factorial =1; for(int i = num; i>0; i--) { factorial = factorial *i; } System.out.println("Factorial is: "+factorial); } }
Output
Factorial is: 24
