Java 程式為不同國家設定日期格式


首先,設定區域設定 -

Locale[] strLocales = { US, UK, GERMANY};

現在,讓我們設定日期格式,即不同的常量 -

int[] constants = { SHORT, MEDIUM, LONG };
String[] str = { "SHORT", "MEDIUM", "LONG" };

迴圈並獲取不同國家/地區的不同日期格式 -

for (Locale country : strLocales) {
   System.out.println("
"+ country.getDisplayCountry() + ".....");    for (int i = 0; i < constants.length; i++) {       dateFormat = DateFormat.getDateInstance(constants[i], country);       System.out.println(str[i] + " constant = " + dateFormat.format(dt));    } }

以下是示例

示例

 線上演示

import static java.text.DateFormat.*;
import static java.util.Locale.*;
import java.text.DateFormat;
import java.util.Date;
import java.util.Locale;
public class Demo {
   public static void main(String[] args) {
      Date dt = new Date();
      Locale[] strLocales = { US, UK, GERMANY};
      int[] constants = { SHORT, MEDIUM, LONG };
      String[] str = { "SHORT", "MEDIUM", "LONG" };
      DateFormat dateFormat = null;
      for (Locale country : strLocales) {
         System.out.println("
"+ country.getDisplayCountry() + ".....");          for (int i = 0; i < constants.length; i++) {             dateFormat = DateFormat.getDateInstance(constants[i], country);             System.out.println(str[i] + " constant = " + dateFormat.format(dt));          }       }    } }

輸出

United States.....
SHORT constant = 11/22/18
MEDIUM constant = Nov 22, 2018
LONG constant = November 22, 2018

United Kingdom.....
SHORT constant = 22/11/18
MEDIUM constant = 22-Nov-2018
LONG constant = 22 November 2018
Germany.....

SHORT constant = 22.11.18
MEDIUM constant = 22.11.2018
LONG constant = 22. November 2018
