Getting hours,minutes, and seconds from Date?
提问by Carlton
I want to get the current hour,minute, and second from the Dateobject.
我想从Date对象中获取当前的小时、分钟和秒。
This is my code:
这是我的代码：
Date date = new Date();
int hour = date.getHours();
But I get a kind of error, the getHours()part doesnt work. I get a "The method getHours() from the type Data is deprecated". What does that mean, and how do I get the hour,minutes, and seconds?
但是我得到了一种错误，该getHours()部分不起作用。我得到一个“来自 Data 类型的方法 getHours() 已被弃用”。这是什么意思，我如何获得小时、分钟和秒？

Use Calendar:
使用Calendar：
Calendar cal = Calendar.getInstance();
cal.setTime(date);
int hours = cal.get(Calendar.HOUR_OF_DAY);
From Datejavadoc:
从Datejavadoc：
Deprecated. As of JDK version 1.1, replaced by
Calendar.get(Calendar.MINUTE).Returns the number of minutes past the hour represented by this date, as interpreted in the local time zone. The value returned is between 0 and 59.
已弃用。从 JDK 1.1 版开始，由
Calendar.get(Calendar.MINUTE).返回此日期表示的小时后的分钟数，如本地时区中所解释的那样。返回值介于 0 到 59 之间。
