  <p>My JAVA code is like this.</p>
  
  <pre><code>    int val=0;
      BufferedReader br = new BufferedReader(new FileReader("out.txt"));
  
      while(true) {
          String line = br.readLine();
          if (line==null) break;
          val=Integer.parseInt(line);
      }
      br.close();
  </code></pre>
