Write a java Program to read a number from command prompt to calculate the factorial using recursion.

In this tutorial, we are going to learn how we can Write a java Program to read a number from command prompt and calculate the factorial using recursion.

Program :-

import java.util.*;

class factorial

{

int fact(int num)

{

if(num>=1)

return num*fact(num-1);

else

return 1;

}

public static void main(String ap[])

{

int n=Integer.parseInt(ap[0]);

factorial f=new factorial();

int ans=f.fact(n);

System.out.println("Factorial of a number is :"+ans);

}

}

Output :-
