java实现斐波那契数列，现在要求输入一个整数n，请你输出斐波那契数列的第n项。 n<=39

public class Solution_feibonaqi
{

public int Fibonacci(int n)
{
int result[] =
{ 0, 1 };
if (n < 2)
{
return result
;
}
int f0 = 0;
int f1 = 1;
int f2 = 0;
for (int i = 2; i <= n; i++)
{
f2 = f1 + f0;
f0 = f1;
f1 = f2;
}
return f2;
}

public static void main(String[] args)
{
Scanner sc = new Scanner(System.in);
int n = sc.nextInt();
Solution_feibonaqi fei = new Solution_feibonaqi();
System.out.println(fei.Fibonacci(n));
}

}
