如何比较Java中的两个字符串日期?
我有两个字符串格式的日期，如下所示 -
I have two dates in String format like below -
String startDate = "2014/09/12 00:00";
String endDate = "2014/09/13 00:00";
我想确保 startDate 应该小于 endDate.startDate 不应大于 endDate.
I want to make sure startDate should be less than endDate. startDate should not be greater than endDate.
如何比较这两个日期并相应地返回布尔值?
How can I compare these two dates and return boolean accordingly?
推荐答案
将它们转换为实际的 Date 对象，然后调用 before.
Convert them to an actual Date object, then call before.
SimpleDateFormat sdf = new SimpleDateFormat("yyyy/MM/dd h:m");
System.out.println(sdf.parse(startDate).before(sdf.parse(endDate)));
回想一下，parse 将抛出 ParseException，因此您应该在此代码块中捕获它，或者将其声明为作为方法签名的一部分抛出.
Recall that parse will throw a ParseException, so you should either catch it in this code block, or declare it to be thrown as part of your method signature.
