return Integer.toString ( SHORTMONTH [ ])+”. ”+ Long.toString (determineGregorianDay ( ) )+”, ”+ Long.toString (determineGregorianYear ( ) %100 );
}


简短一下,其实就是这几句有问题,该如何改呢??

部分代码没有给全!

以及Integer.toString(int para)
API 传递的参数类型不对!

你的代码太厉害了,我都看不出来,到底写的是什么!!
还麻烦你简单的介绍下了!!

就是给出一个具体的日期,比如公元2010年12月31日.这个日期与公元1年1月1日相隔总数多少天.多少年,多少月,跟天数.然后将2010年12月31日的格式写成5种表达形式:12/31/10(年份2010变10),December 31 ,2010,12-31-10, 2010 12 31跟Dec 31,10

API不对?那该怎样改呢?

我把你的第一个方法已经更改了其他的方法已经屏蔽掉了!
你自己把下面的代码copy下 来运行 看看第一个方法是不是你想要的结果!

是这个结果就好了,
其他的方法你对照我写的那个public String returnShortDate()自己修改下吧!!
周末不知道,有问题发帖子求助, 还有很多高手在的!!
我有时间就上来看看!!

其实你的代码 过于很复杂化了!
你自己去看看DateFormat 以及 SimpleDateFormat 定义几个时间日期格式!
直接Format一下就OK了!
最多40行当代码 给你搞得150多行去!!
而且可读性相当的差!!
多看下API吧!
