Question

I need help with this Java Problem as described in the image below:

import java.util.Scanner;

public class LabProgram {

public static int fibonacci(int n) {
/* Type your code here. */
}

public static void main(String[] args) {
Scanner scnr = new Scanner(System.in);
int startNum;

startNum = scnr.nextInt();
System.out.println("fibonacci(" + startNum + ") is " + fibonacci(startNum));
}
}

The Fibonacci sequence begins with 0 and then 1 follows. All subsequent values are the sum of the previous two, for example: 0, 1, 1, 2, 3,
5, 8, 13. Complete the fibonacci() method, which takes in an index (starting at 0), n, and returns the nth value in the sequence. Any negative
index values should return -1.
Ex: If the input is:
7
the output is:
fibonacci (7) is 13
Note: Use recursion and DO NOT use any loops.
