Java Challenge - fibonacci recursive

The fibonacci sequence is a famous bit of mathematics, and it happens to have a recursive definition. The first two values in the sequence are 0 and 1 (essentially 2 base cases). Each subsequent value is the sum of the previous two values, so the whole sequence is: 0, 1, 1, 2, 3, 5, 8, 13, 21 and so on. Define a recursive fibonacci(n) method that returns the nth fibonacci number, with n=0 representing the start of the sequence.

fibonacci(0) → 0
fibonacci(1) → 1
fibonacci(2) → 1

Hisoka :

public int fibonacci(int n) {
  if(n == 0 || n == 1) return n;
  return fibonacci(n-1)+fibonacci(n-2);
}
