Find factorial of a number in Java?

There are two ways to find factorial of a number. One is iterative which is very simple and other is recursive. Following is the code to get factorial by recursive method.

Code :

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31

Output

Factorial of 4 is : 24
