blocks|key|1010293|text|我相信"MMM“会给出Joda的月份名称..。但您需要首先构建一个适当的格式化程序。这是一些示例代码，它在我的盒子上打印"Apr“。(当然，您可以指定相关的区域设置。)|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1010294|import+org.joda.time.*;

I believe "MMM" will give the month name in Joda... but you'd need to build up an appropriate formatter first. Here's some sample code which prints "Apr" on my box. (You can specify the relevant locale of course.)

<pre><code>import org.joda.time.*;
import org.joda.time.format.*;

public class Test
{
 public static void main(String[] args)
 {
 // Year and day will be ignored
 LocalDate date = new LocalDate(2010, 4, 1);
 DateTimeFormatter formatter = DateTimeFormat.forPattern("MMM");
 String month = formatter.print(date);
 System.out.println(month);
 }
}
</code></pre>

My last answer about using <code>java.util.Calendar</code> for this was a little more complicated than it needed to be. Here's a simpler version, although it still requires Java 6 or newer.

<pre><code>import java.util.Calendar;
import java.util.Locale;

public class Test
{
 public static void main(String[] args)
 {
 // Sample usage.
 // Should be "Apr" in English languages
 String month = getMonthNameShort(4);
 System.out.println(month);
 }
 /**
 * @param month Month number
 * @return The short month name
 */
 public static String getMonthNameShort(int month)
 {
 Calendar cal = Calendar.getInstance();
 // Calendar numbers months from 0
 cal.set(Calendar.MONTH, month - 1);
 return cal.getDisplayName(Calendar.MONTH, Calendar.SHORT, Locale.getDefault());
 }
}
</code></pre>

blocks|key|1010375|text|对于Jon的回答，您可以通过使用Joda对datetime类的直接访问来进一步简化这一过程。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1010376|String+month+=+date.toString("MMM");|code-block|syntax|javascript|1010377|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|I|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|J|8|@]|9|@]|A|$E|F]]|$1|G|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|H|$]]

In response to Jon's answer, you can further simplify that by using Joda's direct access for datetime classes.

<pre><code>String month = date.toString("MMM");
</code></pre>

We can do as following:

<pre><code>DateTime dt = new DateTime(); // current time
String monthStr = dt.month().getAsShortText(); // gets the month name
</code></pre>

Also you can use <code>getAsText()</code> method for long month name.

Does anyone know if there's a method in Joda Time or Java itself which takes either an int or a String as an argument, e.g. 4 or "4" and gives the name of the month back in short format, i.e. JAN for January?

I suppose long month names can be truncated and converted to upper case.

How to get short month names in Joda Time?

Java

有没有人知道Joda Time或Java本身中是否有一个方法可以接受int或字符串作为参数，例如4或"4“，并以短格式返回月份的名称，即JAN表示一月？我认为长月份的名称可以被截断并转换为大写。
