为不同国家设置日期格式的 Java 程序
首先,设置语言环境-
Locale[] strLocales = { US, UK, GERMANY};
现在,让我们设置日期格式,即不同的常量-
int[] constants = { SHORT, MEDIUM, LONG }; String[] str = { "SHORT", "MEDIUM", "LONG" };
循环并获取不同国家/地区的不同日期格式-
for (Locale country : strLocales) { System.out.println("\n"+ 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)); } }
下面是一个例子
示例
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("\n"+ 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)); } } } }输出结果
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
