Java的日期API真烂
记得在我刚学Java的时候，真是搞不清楚Date和Calendar这两个类，后来我渐渐知道，原来不能全怪我啊，Java日期API之烂是公认的（不妨参见这篇文章，Tiago Fernandez做过一个投票，就是要选举最烂的Java API，结果Java日期API排行第二，仅次于臭名远扬的EJB2，嘿嘿）。蛋疼的java.sql.Date
只有Date和Calendar搞定一切吗？那还好啊。当然不是！光Date就有java.util.Date和java.sql.Date，而且关系是java.sql.Date extends java.util.Date。为了把前者转成后者，我写了这样的代码：
<div style="font-size: 14px; font-family: Verdana, Arial, Tahoma; vertical-align: baseline; color: #222222; line-height: 21px; text-align: left; padding: 0px; margin: 0px;"><div class="syntaxhighlighterjava" style="margin-top: 1em !important; margin-right: 0px !important; margin-bottom: 1em !important; margin-left: 0px !important; font-style: inherit; font-size: 1em !important; font-family: inherit; vertical-align: baseline; width: 560px; background-color: white !important; padding: 0px;"><div class="line number1 index0 alt2" style="padding-top: 0px !important; padding-right: 0.5em !important; padding-bottom: 0px !important; padding-left: 1em !important; border-top-width: 0px !important; border-right-width: 3px !important; border-bottom-width: 0px !important; border-left-width: 0px !important; border-color: initial !important; font-size: 1em !important; vertical-align: baseline !important; border-top-left-radius: 0px !important; border-top-right-radius: 0px !important; border-bottom-right-radius: 0px !important; border-bottom-left-radius: 0px !important; background-image: none !important; background-color: white !important; float: none !important; height: auto !important; line-height: 1.1em !important; text-align: right !important; width: auto !important; direction: ltr !important; white-space: pre !important; border-right-style: solid !important; border-right-color: #6ce26c !important; margin: 0px !important;">1
