在.property中存储日期并与当前日期进行比较 [英] Storing a date in .property and comparing with current date

问题描述

如何将未来日期存储在.property文件中，并将此日期与当前日期进行比较？

How do I store a future date in a .property file and compare this date with current the current date?

推荐答案

您可以：

1. 保存格式化日期


2. 如果需要，另存为格式，添加灵活性

属性文件：

myDate=25/01/2012
myDate.pattern=dd/MM/yyyy

然后，在你的程序中，你可以这样加载日期：

Then, in your program you could load the date this way:

// choose one of two lines!
String pattern = "dd/MM/yyyy"; // for a fixed format
String pattern = propertyFile.getProperty("myDate.pattern");

String formattedDate = propertyFile.getProperty("myDate");
SimpleDateFormat format = new SimpleDateFormat(pattern);
Date myDate = format.parse(formattedDate);

修改：比较当前的...

Edit: to compare to current...

1. boolean isFuture = myDate.after(new Date())
2. boolean isPast = myDate.before(new Date())
3. int compare = myDate.compareTo(new Date());
// compare < 0 => before
// compare == 0 => equal
// compare > 0 => after
