    public static int factorial(int n) {
        //base case: return 1 (n = 1).
        if (n == 1) {
            return 1;
        }
        else {
            //recursive case: call n * factorial(n-1).
            //5 * 4 * 3 * 2 * 1
            return n * factorial(n-1);
        }
    }
    
    public static void main(String[] args) {
        int n = 5;
        
        //Finding factorial and stores into f variable.
        int f = factorial(n);
        System.out.println(n+"! = "+f);
    }
}
Output
5! = 120
