Question

in java eclipse, Create a program “FibonacciFifteen.java” and a method called “double[] getFibonacci()” that creates an array with a length of 15 that contains the first 15 numbers in the Fibonacci sequence and returns it. Set the first element to 0 and the second element to 1, then use a for loop to fill out the rest of the array by adding the prior two elements.

Answer 1

public class FibonacciFifteen {

    public double[] getFibonacci() {
        double[] f = new double[15];
        f[0] = 0;
        f[1] = 1;
        for (int i = 2; i < f.length; i++) {
            f[i] = f[i-1] + f[i-2];
        }
        return f;
    }

    public static void main(String[] args) {
        double[] fibonacciNumbers = new FibonacciFifteen().getFibonacci();
        System.out.println("First 15 fibonacci numbers are");
        for (int i = 0; i < fibonacciNumbers.length; i++) {
            System.out.println(fibonacciNumbers[i]);
        }
    }
}
