用类代替资源文件

1  Hello.java

package local;
import java.text.MessageFormat;
import java.text.DateFormat;
import java.text.Format;
import java.util.ResourceBundle;
import java.util.Locale;
import java.util.Date;

public class Hello {
 public static void main(String args[]){
  Locale currentLocale=null;
  if(args.length==2){
   currentLocale=new Locale(args[0],args[1]);
   
  }else{
   currentLocale=Locale.getDefault();
  }
  ResourceBundle bundle=ResourceBundle.getBundle("MyResource", currentLocale);
  String msg=(String)bundle.getObject("msg");
  MessageFormat mf=new MessageFormat("");
  mf.setLocale(currentLocale);
  mf.applyPattern(msg);
  Date now=new Date();
  Object[] msgParams={"yeeku",now};
  System.out.println(mf.format(msgParams));
 }

}

 

 

2   MyResource.java

import java.util.ListResourceBundle;
import java.util.Locale;

public class MyResource extends ListResourceBundle
{
 //定义资源
 private final Object myData[][]=
 {
  {"msg","Hello Class,{0}!Today is {1}."}
 };
 //实现抽象方法getContents()
 public Object[][] getContents()
 {
  return myData;
 } 
}

 

3  MyResource_zh_CN.java

 

import java.util.ListResourceBundle;

public class MyResource_zh_CN extends ListResourceBundle {
    //定义资源
   private final Object myData[][]={
     {"msg","{0},您好！今天是{1}"}
   };
 //重写方法
 protected Object[][] getContents() {
  
  return myData;
 }

}
