如何获得本地化的短周日名称（Mo/Tu/We/Th ...）

Question

我可以获得本地化的短周日名称（Mo/Tu/We/Th/Fr/Sa/Su for English）在Java中？

Answer 1

的最好方法是使用的SimpleDateFormat java.text.DateFormatSymbols中

DateFormatSymbols symbols = new DateFormatSymbols(new Locale("it")); 
// for the current Locale : 
// DateFormatSymbols symbols = new DateFormatSymbols(); 
String[] dayNames = symbols.getShortWeekdays(); 
for (String s : dayNames) { 
    System.out.print(s + " "); 
} 
// output : dom lun mar mer gio ven sab 

Answer 2

你不能使用Calendar类（除非你自己写），但你可以使用Date类。 （这两者通常是手牵手使用的）。

下面是一个例子：

import java.util.Date; 

public class DateFormatExample { 

    public static void main(String[] args) { 
    Calendar nowCal = Calendar.getInstance(); // a Calendar date 
    Date now = new Date(nowCal.getTimeInMillis()); // convert to Date 
    System.out.printf("localized month name: %tB/%TB\n", now, now); 
    System.out.printf("localized, abbreviated month: %tb/%Tb\n", now, now); 
    System.out.printf("localized day name: %tA/%TA\n", now, now); 
    System.out.printf("localized, abbreviated day: %ta/%Ta\n", now, now); 
    } 
} 

输出：

localized month name: June/JUNE 
localized, abbreviated month: Jun/JUN 
localized day name: Friday/FRIDAY 
localized, abbreviated day: Fri/FRI 

Answer 3

一个例子：

Date now = new Date(); 
// EEE gives short day names, EEEE would be full length. 
SimpleDateFormat dateFormat = new SimpleDateFormat("EEE", Locale.US); 
String asWeek = dateFormat.format(now); 

SimpleDateFormat比C风格的String.format和System.out.printf长，我想你会发现大多数Java开发人员会更熟悉它，并且在现有的代码库中使用的更多， d建议这种方法。

Answer 4

如果标准缩写是细跟你，只使用Calendar类是这样的：

myCal.getDisplayName(Calendar.DAY_OF_WEEK, Calendar.SHORT, Locale.US); 

Answer 5

//you need to use joda library   
List<String> dayList = new ArrayList<String>(); 
String[] days = new String[7]; 
int a=2; 
//a =starting day of week 1=sunday ,2=monday 
Calendar c2 = Calendar.getInstance(); 
SimpleDateFormat df = new SimpleDateFormat("yyyy-MM-dd"); 
c2.set((Calendar.DAY_OF_WEEK),a); 
int maxDay = c2.getActualMaximum(Calendar.DAY_OF_WEEK); 
for(int i=0;i<maxDay;i++) 
{     
    days[i] = df.format(c2.getTime()); 
    c2.add(Calendar.DAY_OF_MONTH, 1); 
    String dayOfWeek = new LocalDate(days[i]).dayOfWeek().getAsShortText(); 
    dayList.add(dayOfWeek);   
}    
for(int i=0;i<maxDay;i++) 
{ 
    System.out.print(" '"+dayList.get(i)+"'"); 
}    

Answer 6

这是相当晚来回答这个问题，但只是想与Java 8

更新答案

ZoneId zoneId = ZoneId.of("America/Los_Angeles"); 

Instant instant = Instant.now(); 

ZonedDateTime zDateTime = ZonedDateTime.ofInstant(instant, zoneId); 

DayOfWeek day = zDateTime.getDayOfWeek(); 

System.out.println(day.getDisplayName(TextStyle.SHORT, Locale.US)); 
System.out.println(day.getDisplayName(TextStyle.NARROW, Locale.US));
