问题描述
我正在阅读文本并将日期存储为 LocalDate 变量.
I am reading text and storing the dates as LocalDate variables.
我有什么办法可以保留 DateTimeFormatter 的格式,这样当我调用 LocalDate 变量时它仍然是这种格式.
Is there any way for me to preserve the formatting from DateTimeFormatter so that when I call the LocalDate variable it will still be in this format.
我希望 parsedDate 以 25/09/2016 的正确格式存储,而不是作为字符串打印
I want the parsedDate to be stored in the correct format of 25/09/2016 rather than printing as a string
我的代码:
public static void main(String[] args)
{
LocalDate date = LocalDate.now();
DateTimeFormatter formatters = DateTimeFormatter.ofPattern("d/MM/uuuu");
String text = date.format(formatters);
LocalDate parsedDate = LocalDate.parse(text, formatters);
System.out.println("date: " + date); // date: 2016-09-25
System.out.println("Text format " + text); // Text format 25/09/2016
System.out.println("parsedDate: " + parsedDate); // parsedDate: 2016-09-25
// I want the LocalDate parsedDate to be stored as 25/09/2016
}
推荐答案
考虑到您的编辑,只需将 parsedDate 设置为等于您的格式化文本字符串,如下所示:
Considering your edit, just set parsedDate equal to your formatted text string, like so:
parsedDate = text;

LocalDate 对象只能以 ISO8601 格式 (yyyy-MM-dd) 打印.为了以其他格式打印对象,您需要对其进行格式化并将 LocalDate 保存为字符串,就像您在自己的示例中演示的那样
A LocalDate object can only ever be printed in ISO8601 format (yyyy-MM-dd). In order to print the object in some other format, you need to format it and save the LocalDate as a string like you've demonstrated in your own example
DateTimeFormatter formatters = DateTimeFormatter.ofPattern("d/MM/uuuu");
String text = date.format(formatters);
