问题描述

How do I get the current date in Java?
在C#中,它是 DateTime.Now
。 / p>
In C# it is DateTime.Now
.
推荐答案
只需构造一个新的 Date
这将分配当前日期和时间到新对象。
Just construct a new Date
object without any arguments; this will assign the current date and time to the new object.
import java.util.Date;
Date d = new Date();
分配一个Date对象,初始化它,以便它表示分配时间,测量到最接近的毫秒。
Allocates a Date object and initializes it so that it represents the time at which it was allocated, measured to the nearest millisecond.
确保使用 java.util.Date
而不是 java.sql.Date
- 后者没有一个零参数构造函数,并且有一些不同的语义是完全不同的对话的主题。 :)
Make sure you're using java.util.Date
and not java.sql.Date
-- the latter doesn't have a zero-arg constructor, and has somewhat different semantics that are the topic of an entirely different conversation. :)
