在Java中如何说5秒？ [英] How do I say 5 seconds from now in Java?

问题描述

我正在查看日期文档并试图找出我如何表达现在+ 5秒。这里有一些伪代码：

I am looking at the Date documentation and trying to figure out how I can express NOW + 5 seconds. Here's some pseudocode:

import java.util.Date
public class Main {

    public static void main(String args[]) {
         Date now = new Date();
         now.setSeconds(now.getSeconds() + 5);
    }
}

推荐答案

一个href =http://java.sun.com/javase/6/docs/api/java/util/Date.html =noreferrer> Date 几乎完全被弃用，还在向后兼容性原因如果您需要设置特定日期或日期算术，请使用日历：

Date is almost entirely deprecated and is still there for backward compatibility reasons. If you need to set particular dates or do date arithmetic, use a Calendar:

Calendar calendar = Calendar.getInstance(); // gets a calendar using the default time zone and locale.
calendar.add(Calendar.SECOND, 5);
System.out.println(calendar.getTime());
