In this article we are going to print factorial of a number using recursive function. Recursive function is function called by itself during its execution . See the below example.
import java.util.Scanner;
public class FactorialRecursive {
int fact(int n)
{
int result;
if(n==0 || n==1)
return 1;
result = fact(n-1) * n;
return result;
}
public static void main(String[] args) {
System.out.println("Please Enter Number: ");
Scanner read = new Scanner(System.in);
int a = read.nextInt();
int factorial = new FactorialRecursive().fact(a);
System.out.println("The factorial of given number is " + factorial);
}
}
