Java recursive Fibonacci sequence

To implement a recursive Fibonacci sequence in Java, you can define a recursive method that returns the nth number in the sequence.

Here's an example of how you can implement a recursive Fibonacci sequence in Java:

public class Main {
  public static void main(String[] args) {
    for (int i = 0; i < 10; i++) {
      System.out.println(fibonacci(i));
    }
  }

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

This code defines a main method that calls the fibonacci method 10 times and prints the results to the console. The fibonacci method is a recursive method that returns the nth number in the Fibonacci sequence.

The Fibonacci sequence is defined as follows:

  • F(0) = 0
  • F(1) = 1
  • F(n) = F(n-1) + F(n-2) (for n > 1)

The fibonacci method uses this definition to compute the nth number in the Fibonacci sequence. If n is 0 or 1, it returns n; otherwise, it returns the sum of the previous two numbers in the sequence.
