Introduction

The below-given program lists the factorial of 1 to 20 and is a good example of Recursive Function in java:

Code

public class RecursiveFunction {
public static void main(String[] args) {
System.out.println("Number\t\tFactorial");
for (int i = 0; i <= 20; i++) {
System.out.println(i + "\t\t" + Factorial(i));
}
}
public static long Factorial(long x) {
if (x == 0) {
return 1;
} else {
return Factorial(x - 1) * x;
}
}
}

Output

Number	Factorial
0	1
1	1
2	2
3	6
4	24
5	120
6	720
7	5040
8	40320
9	362880
10	3628800
11	39916800
12	479001600
13	6227020800
14	87178291200
15	1307674368000
16	20922789888000
17	355687428096000
18	6402373705728000
19	21645100408832000
