برنامج جافا لحساب عاملي عدد معين باستخدام الركيرشن

java Program to demonstrate the use of recursion to find the factorial of a given number.

import java.util.Scanner;

class Factorial

{

public static void main(String args[])

{

int n, c, f = 1;

System.out.println("Enter number");

Scanner in = new Scanner(System.in);

n = in.nextInt();

if (n < 0)

System.out.println("Number should be non-negative.");

else

{

for (c = 1; c <= n; c++)

f = f*c;

System.out.println("Factorial of "+n+" is = "+f);

}

}

} 

output:

Enter number

9

Factorial of 9 is = 362880
