如何获得今天的日期？ [英] How to get today's Date?

问题描述

换句话说，我想要提供Joda-Time的功能：

  today = today.withTime（0，0， 0，0）; 
  

但没有Joda-Time，只有java.util.Date。

不推荐使用.setHours（）等方法。是否有更正确的方式？

解决方案

  Date today = new Date（）; 
 today.setHours（0）; //分钟和秒相同
  

由于方法已被弃用，您可以使用日历：

  Calendar today = Calendar.getInstance（）; 
 today.set（Calendar.HOUR_OF_DAY，0）; //分钟和秒相同
  

如果你需要一个 Date 对象到底，只需调用 now.getTime（）

In other words, I want functionality that provides Joda-Time:

today = today.withTime(0, 0, 0, 0);

but without Joda-Time, only with java.util.Date.

Methods such as .setHours() and etc. are deprecated. Is there are more correct way?

解决方案

Date today = new Date();
today.setHours(0); //same for minutes and seconds

Since the methods are deprecated, you can do this with Calendar:

Calendar today = Calendar.getInstance();
today.set(Calendar.HOUR_OF_DAY, 0); // same for minutes and seconds

And if you need a Date object in the end, simply call now.getTime()
