Java file as url

 A file can be read as URL with the java.net package. You must provide absolute path after the URI scheme name file://.

package com.demo.io;

import java.io.*;
import java.net.*;

public class FileAsURL {
    public static void main(String[] args) throws Exception {
 URL url = new URL("file:///tmp/com/demo/io/test.txt");
 URLConnection conn = url.openConnection();
 BufferedReader r = new BufferedReader(
    new InputStreamReader(
        conn.getInputStream()
    )
      );
 String l = r.readLine();
 while (l != null) {
     System.out.println(l);
     l = r.readLine();
 }
    }
}
