factorial using recursive

can please give this code !i am going to do a factorial function using recursion definition and then . my professor told me that we are going to create a three screen.

the first screen should be input an MAIN MENU then above that RECURSION below that again the EXIT BUTTON.. then second screen SHOULD BE INPUT an meaning of recursion and about information and also types of recursion below that create a text box to put a :ENTER YOUR CHOOSE:,AND EXIT AND CLOSE BUTTON. last screen is the meaning of recursion and uses and then their syntax. below that input a : DO YOU WANT TO CONTINUE: YES OR NO..after that if yes : ENTER NUMBER: id try again input another number. if no back to the main menu>

please help for this project! thank you!

 public double factorialRecursion(int number)
{
    if (number == 1)
        return 1;
    else
        return number * factorialrecursion(number - 1);
}

Here is an example that calculates the factorial number using recursion

public class FactorialExample{
public static long factorial(int n){
if(n <= 1) 
return 1;
else
return n * factorial(n - 1);
}
public static void main(String [] args){
    int num=5;
System.out.println(factorial(num));
}
}
