Java--Niit-ch2--Location本地化问题

Localizing Data:

getTimeInstance--表示时间

package CHAP2;

import java.text.DateFormat;
import java.util.Date;
import java.util.Locale;

public class DataDemo {
    public static void main(String[] args) {
        DateFormat df=DateFormat.getTimeInstance(DateFormat.LONG, new Locale("de","DE"));
                String date =df.format(new Date());
        System.out.print(date);
        
        
    }
}

getDateInstance--表示日期：

package CHAP2;

import java.text.DateFormat;
import java.util.Date;
import java.util.Locale;

public class DataDemo {
    public static void main(String[] args) {
        DateFormat df=DateFormat.getDateInstance(DateFormat.LONG, new Locale("de","DE"));
                String date =df.format(new Date());
        System.out.print(date);
        
        
    }
}

Localizing Currency:

package CHAP2;

import java.text.NumberFormat;
import java.util.Locale;

public class CurrencyDemo {
    static int number=1000000;
    public static void main(String args[]) {
        NumberFormat nft =NumberFormat.getCurrencyInstance(new Locale ("de","DE"));
        String formatted =nft.format(number);
        System.out.println(formatted);
        
    }

}

Localizing Text:
1.先创建2个文件（new-file）：

文件一：命名：

MessageBundle_de.properties

文件二：命名：

MessageBundle_zn.properties

package CHAP2;

import java.util.*;

public class TestLocale {
    public static void main(String args[]) {
        Locale l1=new Locale("de","DE");
        ResourceBundle rb1=ResourceBundle.getBundle("CHAP2.MessageBundle",l1);
        System.out.println(rb1.getString("message"));    
        Locale l2=new Locale("zn","ZN");
        ResourceBundle rb2=ResourceBundle.getBundle("CHAP2.MessageBundle",l2);
        System.out.println(rb2.getString("message"));
        
    }
}

注：ResourceBundle rb1=ResourceBundle.getBundle("CHAP2.MessageBundle",l1);

要写："CHAP2.MessageBundle"
