以不同国家/地区格式显示时间的Java程序

Locale 类和 DateFormat 类用于显示时间不同的 Country Format。

Java中的 DateFormat 类用于格式化日期。指定的日期可以格式化为数据/时间字符串。例如，日期可以格式化为：mm/dd/yyyy。日期格式类不同步。 Locale 对象在逻辑上由语言、脚本、国家、变体、扩展等字段组成。

Java Locale 类对象表示特定的地理、文化或政治区域。

代码：

import java.text.DateFormat;
import java.util.*;
  
public class Main {
    public static void main(String[] args) throws Exception
    {
        Date d1 = new Date();
  
        // creating a new locale for England Format
        Locale locEngland = new Locale("en", "ch");
  
        // initializing the date formatter and converting
        // the date
        DateFormat de = DateFormat.getDateInstance(
                        DateFormat.FULL, locEngland);
