Java 实现斐波那契数列

public class Fibonacci {

    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) + "	");
            if (j % 5 == 0) {
                System.out.println();
            }
        }
    }
}
