Factorial Program using recursion in java

In this example, we will see a Java program to find the factorial of any given input number.

Factorial of any number "n" is basically the product of all the positive integers less than the given number. Factorial of n is denoted by n!.

In this program, we will be using recursion to find the factorial of the given number.

Program


class Main
{  
 static int factorial(int n)
 {    
  if (n == 0)    
  return 1;    
  else    
  return(n * factorial(n-1));    
 }    
 public static void main(String args[])
 {  
  int i,fact=1;  
  int number=9;//It is the number to calculate factorial    
  fact = factorial(number);   
  System.out.println("Factorial of "+number+" is: "+fact);    
 }  
}

Output:
Factorial of 9 is: 362880
