In this core java programming tutorial we will write a program to generate Fibonacci series using recursion in java.
0 1 1 2 3 5 8 13 21 34 55 89.
First number of series is 0 & second number of series is 1.
So, logic behind the series generation is that the subsequent number generated is sum of previous two number of series in java.

public class FibonacciRecursionExample {
public static void main(String...args) {
int n = 10; //generate series upto n.
System.out.print("FibonacciSeries : 0 1 ");
for(int i=2; i<=n; i++){
System.out.print(fibonacciRecursion(i) +" ");
}
}
/*
* return next number of FibonacciSeries using recursion.
*/
public static int fibonacciRecursion(int n){
if(n == 1 || n == 2){
return 1;
}
return fibonacciRecursion(n-1) + fibonacciRecursion(n-2); //using tail recursion
}
}
/*OUTPUT
FibonacciSeries : 0 1 1 2 3 5 8 13 21 34 55
