Answer 1

Calculate factorial using recursion in JAVA.

class FindFactorial{

   public static void main(String args[]){

      int factorial = fact(5);

      System.out.println("Factorial of 5 is: "+factorial);

   }

   static int fact(int n)

   {

       int output;

       if(n==1){

         return 1;

       }

       //Recursion: Function calling itself!!

       output = fact(n-1)* n;

       return output;

   }

}

Output:

 

Factorial of 5 is: 120
