Think in Java第四章练习题

代码如下：

package cn.thinkinjava.yys;

public class Exercise9 {   public static int num(int n) {        if(n == 1){            return 1;        }        if (n == 2) {            return 1;        }else{            return num(n - 1) + num(n - 2);        }    }    public static void main(String[] args) {        int i = Integer.parseInt(args[0]);        System.out.println("First"+i+"Fibonacci number(s):");        for (int j = 0; j <= i; j++) {            System.out.println(num(j));        }    }}

运行一直出错
