包结构 
-src 
-test_1 
   TEST.java 
  --test_1.test_2 
    hello_en.txt 
hello_zh.txt 




方法一 

 package test_1;

 import java.io.BufferedReader;
 import java.io.File;
 import java.io.IOException;
 import java.io.InputStream;
 import java.io.InputStreamReader;
 import java.net.URISyntaxException;
 import java.net.URL;

 public class Test {
     public static void main(String[] args) throws URISyntaxException,
             IOException {

         URL url = Test.class.getResource("/hello_zh.txt");

         File file = new File(url.getFile());
         System.out.println(file);
         InputStream in = url.openStream();
         BufferedReader br=new BufferedReader(new InputStreamReader(in));
         String s="";
         while((s=br.readLine())!=null)
             System.out.println(s);

     }
 }
