Java Program Fibonacci Series Using Recursion

In this Java program, I show you how to calculate the Fibonacci series of a given number using a recursive algorithm where the fibonacci() method calls itself to do the calculation.

Fibonacci series is a sequence of values such that each number is the sum of the two preceding ones, starting from 0 and 1. The beginning of the sequence is thus:
```
0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144 ...
```

Output:
Enter a number: 100 1 1 2 3 5 8 13 21 34
