生手求教，数组_J2SE

新手求教，数组。


class  ArrayTestWeek
{
	public static void main(String[] args) 
	{
		String weeks=getWeek(2);
		System.out.println(weeks);
	}
	public static String getWeek(int num)
	{
		if(num>7||num<1)
			return num+"没有对应的星期";
		
		String[] weeks={"星期一","星期二","星期三","星期四","星期五","星期六","星期日"};
		return weeks[num-1];
	}
}

上面这个编译通过，且可以成功运行的，但是我在if语句后加了个else，就出现编译错误，是什么情况？


class  ArrayTestWeek
{
	public static void main(String[] args) 
	{
		String weeks=getWeek(2);
		System.out.println(weeks);
	}
	public static String getWeek(int num)
	{
		if(num>7||num<1)
			return num+"没有对应的星期";
		else
		String[] weeks={"星期一","星期二","星期三","星期四","星期五","星期六","星期日"};
		return weeks[num-1];
	}
}

------解决方案--------------------
将else里面扩起来试试


else {
        String[] weeks={"星期一","星期二","星期三","星期四","星期五","星期六","星期日"};
        return weeks[num-1];
}
