java从日期开始获得小时、分钟和秒？

Question

我想从Date对象获取当前的小时、分钟和秒

这是我的代码：

Date date = new Date();
int hour = date.getHours();

但是我得到了一种错误，getHours()部分不起作用。我得到一个“类型数据中的getHours（）方法已弃用”。这意味着什么？我如何计算小时、分钟和秒

Answer 1

使用^{}：

Calendar cal = Calendar.getInstance();
cal.setTime(date);  
int hours = cal.get(Calendar.HOUR_OF_DAY);

从Date{a2}

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.
