斐波那契数列java完整代码

以下是使用数组循环、递归和递归方法实现斐波那契数列的完整代码：

使用数组循环：

public class test4 {
    public static void main(String[] args) {
        int[] arr = new int = 1;
        arr = 1;
        for (int i = 2; i < arr.length; i++) {
            arr[i = arr[i - 1 + arr[i - 2];
        }
        String s = Arrays.toString(arr);
        System.out.println("前十个斐波那契数是：" + s);
    }
}

使用递归方法：

public class Demo2 {
    private static int getFibo(int i) {
        if (i == 1 || i == 2)
            return 1;
        else
            return getFibo(i - 1) + getFibo(i - 2);
    }

    public static void main(String[] args) {
        System.out.println("斐波那契数列的前20项为：");
        for (int j = 1; j <= 20; j++) {
            System.out.print(getFibo(j) + "\t");
            if (j % 5 == 0)
                System.out.println();
        }
    }
}

使用递归的方法：

public class test2 {
    public static void main(String[] args) {
        for (int counter = 1; counter <= 10; counter++) {
            System.out.printf("Fibonacci of %d is: %d\n", counter, fibonacci(counter));
        }
    }

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

请注意，以上代码是完整的斐波那契数列的实现。不同的代码使用了不同的方法来计算斐波那契数列，你可以根据自己的需要选择其中一个方法来使用。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
