If you just need to output a time stamp in format YYYY.MM.DD-HH.MM.SS (very frequent case) then here's the way to do it:

<pre><code>String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss").format(Calendar.getInstance().getTime());

blocks|key|981941|text|如前所述，就获取当前时间而言，基本的Date()可以做您需要做的事情。根据我最近大量使用Java+Date的经验，内置类有很多奇怪之处(以及许多Date类方法的弃用)。对我来说，一个奇怪的地方是月份是基于0指数的，这从技术角度来看是有意义的，但在实际情况下可能会非常令人困惑。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|981942|如果你只关心当前的日期就足够了--然而，如果你打算对日期进行大量的操作/计算，那么使用第三方库可能是非常有益的(之所以存在这么多库，是因为许多Java开发人员对其内置功能不满意)。|981943|我同意Stephen+C的建议，因为我发现Joda-time在简化我处理日期的工作方面非常有用，它也有很好的文档记录，你可以在web上找到许多有用的例子。我甚至最终编写了一个静态包装类(如DateUtils)，用于合并和简化所有常见的日期操作。|981944|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|H|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|I|8|@]|9|@]|A|$]]|$1|D|3|E|5|6|7|J|8|@]|9|@]|A|$]]|$1|F|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|G|$]]

As mentioned the basic Date() can do what you need in terms of getting the current time. In my recent experience working heavily with Java dates there are a lot of oddities with the built in classes (as well as deprecation of many of the Date class methods). One oddity that stood out to me was that months are 0 index based which from a technical standpoint makes sense, but in real terms can be very confusing.

If you are only concerned with the current date that should suffice - however if you intend to do a lot of manipulating/calculations with dates it could be very beneficial to use a third party library (so many exist because many Java developers have been unsatisfied with the built in functionality).

I second Stephen C's recommendation as I have found Joda-time to be very useful in simplifying my work with dates, it is also very well documented and you can find many useful examples throughout the web. I even ended up writing a static wrapper class (as DateUtils) which I use to consolidate and simplify all of my common date manipulation.

I created this methods, it works for me...

<pre><code>public String GetDay() {
 return String.valueOf(LocalDateTime.now().format(DateTimeFormatter.ofPattern("dd")));
}

public String GetNameOfTheDay() {
 return String.valueOf(LocalDateTime.now().getDayOfWeek());
}

public String GetMonth() {
 return String.valueOf(LocalDateTime.now().format(DateTimeFormatter.ofPattern("MM")));
}

public String GetNameOfTheMonth() {
 return String.valueOf(LocalDateTime.now().getMonth());
}

public String GetYear() {
 return String.valueOf(LocalDateTime.now().format(DateTimeFormatter.ofPattern("yyyy")));
}

public boolean isLeapYear(long year) {
 return Year.isLeap(year);
}

public String GetDate() {
 return GetDay() + "/" + GetMonth() + "/" + GetYear();
}

public String Get12HHour() {
 return String.valueOf(LocalDateTime.now().format(DateTimeFormatter.ofPattern("hh")));
}

public String Get24HHour() {
 return String.valueOf(LocalDateTime.now().getHour());
}

public String GetMinutes() {
 return String.valueOf(LocalDateTime.now().format(DateTimeFormatter.ofPattern("mm")));
}

public String GetSeconds() {
 return String.valueOf(LocalDateTime.now().format(DateTimeFormatter.ofPattern("ss")));
}

public String Get24HTime() {
 return Get24HHour() + ":" + GetMinutes();
}

public String Get24HFullTime() {
 return Get24HHour() + ":" + GetMinutes() + ":" + GetSeconds();
}

public String Get12HTime() {
 return Get12HHour() + ":" + GetMinutes();
}

public String Get12HFullTime() {
 return Get12HHour() + ":" + GetMinutes() + ":" + GetSeconds();
}
</code></pre>

blocks|key|982563|text|使用java8的当前日期:首先，让我们使用java.time.LocalDate来获取当前系统日期：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|982564|LocalDate+localDate+=+LocalDate.now();|code-block|syntax|javascript|982565|要获取任何其他时区的日期，我们可以使用LocalDate.now(ZoneId)：|982566|LocalDate+localDate+=+LocalDate.now(ZoneId.of("GMT%2B02:30"));|982567|我们还可以使用java.time.LocalDateTime来获取LocalDate的一个实例：|982568|LocalDateTime+localDateTime+=+LocalDateTime.now();
LocalDate+localDate+=+localDateTime.toLocalDate();|982569|entityMap^0|0|0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|Q|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|R|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|S|8|@]|9|@]|A|$]]|$1|I|3|J|5|D|7|T|8|@]|9|@]|A|$E|F]]|$1|K|3|L|5|6|7|U|8|@]|9|@]|A|$]]|$1|M|3|N|5|D|7|V|8|@]|9|@]|A|$E|F]]|$1|O|3|-4|5|6|7|W|8|@]|9|@]|A|$]]]|P|$]]

Current Date using java 8:
First, let's use java.time.LocalDate to get the current system date:

<pre><code>LocalDate localDate = LocalDate.now();
</code></pre>

To get the date in any other timezone we can use LocalDate.now(ZoneId):

<pre><code>LocalDate localDate = LocalDate.now(ZoneId.of("GMT+02:30"));
</code></pre>

We can also use java.time.LocalDateTime to get an instance of LocalDate:

<pre><code>LocalDateTime localDateTime = LocalDateTime.now();
LocalDate localDate = localDateTime.toLocalDate();
</code></pre>

blocks|key|767324|text|我将继续输入这个答案，因为当我有同样的问题时，它就是我所需要的：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|767325|Date+currentDate+=+new+Date(System.currentTimeMillis());|code-block|syntax|javascript|767326|currentDate现在是您在Java+Date对象中的当前日期。|offset|length|style|CODE|767327|entityMap^0|0|0|0|B|L|4|0^^$0|@$1|2|3|4|5|6|7|O|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|P|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|Q|8|@$I|R|J|S|K|L]|$I|T|J|U|K|L]]|9|@]|A|$]]|$1|M|3|-4|5|6|7|V|8|@]|9|@]|A|$]]]|N|$]]

I'll go ahead and throw this answer in because it is all I needed when I had the same question:

<pre><code>Date currentDate = new Date(System.currentTimeMillis());
</code></pre>

<code>currentDate</code> is now your current date in a Java <code>Date</code> object.
