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 ...
```

Java Fibonacci series program using a recursive algorithm where the fibonacci() method calls itself to do the calculation.
/**  *   */ package net.javaguides.corejava.programs; import java.math.BigInteger; import java.util.Scanner; /**  * The program calculates the fibonacci sequence of given number.  * @author Ramesh Fadatare  *  */ public class FibonacciRecursiveProgram { public static BigInteger fibonacci(int n) { if (n <= 1) return BigInteger.valueOf(n); return fibonacci(n - 2).add(fibonacci(n - 1)); } public static void main(String[] args) { Scanner scanner = new Scanner(System.in); System.out.print("Enter a number: "); int n = scanner.nextInt(); for (int i = 0; i < n; i++) { BigInteger value = fibonacci(i); System.out.print( value + "\t"); } scanner.close(); } }
Output:
Enter a number: 10 0 1 1 2 3 5 8 13 21 34
