Question

我在计划上将11-12年之间的ger化转换成相应的月名称。 (例如1-> 1月2日至> 2月)等,在一份说明中使用 Java日历级。

注:我只使用 Java日历类。 Don t建议任何开关或铺面办法。

感谢。

Answer 1

rel=“nofollow noreferer”>。班级不是在获得地方化月名称时使用的最佳班级。

以下是仅使用<代码>Calendar类别(1月1日)获得<编码>t<<>>t规定的月份名称的实例:

// Month as a number.
int month = 1;

// Sets the Calendar instance to the desired month.
// The "-1" takes into account that Calendar counts months
// beginning from 0.
Calendar c = Calendar.getInstance();
c.set(Calendar.MONTH, month - 1);

// This is to avoid the problem of having a day that is greater than the maximum of the
// month you set. c.getInstance() copies the whole current dateTime from system 
// including day, if you execute this on the 30th of any month and set the Month to 1 
// (February) getDisplayName will get you March as it automatically jumps to the next              
// Month
c.set(Calendar.DAY_OF_MONTH, 1);    

// Returns a String of the month name in the current locale.
c.getDisplayName(Calendar.MONTH, Calendar.LONG, Locale.getDefault());

上述法典将在本系统中重新命名。

Answer 2

使用<代码>DateFormatSymbols

Proudly copied and pasted from 。

import java.text.*;

String getMonthForInt(int m) {
    String month = "invalid";
    DateFormatSymbols dfs = new DateFormatSymbols();
    String[] months = dfs.getMonths();
    if (m >= 0 && m <= 11 ) {
        month = months[m];
    }
    return month;
}

Answer 4

tl;dr

Month.of( 12 ).getDisplayName( TextStyle.FULL , Locale.US )

......

Month.DECEMBER.getDisplayName( TextStyle.FULL , Locale.US )

12月

Using java.time

获取一个月当地化名称的现代途径是java。页: 1 这一类别是 j的一部分。现在,一揽子时间计划取代诸如<代码>Date和Calendar等老旧的遗产日记。

• 为地方化,具体规定:

TextStyle to determine how long or abbreviated should the string be.
Locale to determine (a) the human language for translation of name of day, name of month, and such, and (b) the cultural norms deciding issues of abbreviation, capitalization, punctuation, separators, and such.

例码。

Month month = Month.of( 7 );
String outputConstantName = month.toString();
String outputMonthNameEnglish = month.getDisplayName( TextStyle.FULL , Locale.US );
String outputMonthQuébec = month.getDisplayName( TextStyle.FULL , Locale.CANADA_FRENCH );

采用<代码>Month,按名称而不是月数对 objects,可以是手法,易于阅读,较少发生错误。

String output = Month.JULY.getDisplayName( TextStyle.FULL , Locale.US ) ;
