Java Program that prompts user to enter an index and computes the Fibonacci number for that index, using recursive method.

Code:

import java.util.Scanner;
public class Fib
 {
      public static void main(String args[])
      {
           int n;
           Scanner s=new Scanner(System.in);
           System.out.println("Enter number upto which Fibonacci series should be printed : ");
           n=s.nextInt();
           System.out.println("Fibonacci series upto " + n+ " is  ");
           for(int i=1; i<=n; i++)
           {
                 System.out.print(recursion(i) +" ");
          }
    }
    static int recursion(int num)
    {
        if(num == 1 || num == 2)
        {
            return 1;
        }
        return recursion(num-1) + recursion(num -2);
     }
 }

Output:
