    public static void main(String[] args) {
        System.out.println(today());
        System.out.println(oneDay(1989, 9, 10));
    }
}

运行效果：

2012年10月7日 星期日 农历壬辰(龙)年八月廿二
2012年10月7日 星期日 农历己巳(蛇)年八月初十

注：第二条输出记录，我们有做处理，所以输出的是当前的日期，你也可以自己写一个方法，如：oneDay(int year,int month,int day)

自己实现自己想要的输出结果.

遗憾的事总是有滴，就是这样一个问题：

//如果我现在给出了农历，如：农历壬辰(龙)年八月廿二<br>
//我想要输出公历：2012年10月7日 星期日<br>

如果大家看了这篇blog后，知道怎样解决这个问题，大家可以一起交流，共同学习。
