Issue with SimpleDateFormat's milliseconds
提问by Pith
I tried this snippet code and the output is very surprising. Why the output is different from the input? Did I make a mistake or is there a problem with SimpleDateFormat?
我尝试了这个片段代码，输出非常令人惊讶。为什么输出与输入不同？是我弄错了还是 SimpleDateFormat 有问题？
SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd-HH.mm.ss.SSS");
try {
Date date = sdf.parse("2013-04-18-19.01.33.080");
System.out.println(sdf.format(date)); // output: 2012-04-18-19.01.33.80
} catch (ParseException e) {
e.printStackTrace();
}
EDIT:In fact, I checked my code and I wrote yyyy-MM-dd-HH.mm.ss.Sinstead of yyyy-MM-dd-HH.mm.ss.SSS. It was a stupid mistake. Thanks all for your answers.
编辑：事实上，我检查了我的代码，我写的yyyy-MM-dd-HH.mm.ss.S不是yyyy-MM-dd-HH.mm.ss.SSS. 这是一个愚蠢的错误。谢谢大家的回答。

This works fine for me, If it doesn't work for you try setting Localeexplicitly
这对我来说很好，如果它对你不起作用，请尝试Locale明确设置
SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd-HH.mm.ss.SSS", Locale.ENGLISH);
