包结构
-src
-test_1
   TEST.java
  --test_1.test_2
    hello_en.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); 

	}
}
