title: Exception in Connection time out for HttpURLConnection in Java programming
body: <p>Here's the problem, I would like to write a Java program to increase the page hit for specific URL. And currently I just surfed in the Internet and get some basic program to do the testing. However, I even couldn't get the program running... Below is my program and related output.</p>
  
  <p>Eclipse, Java program:</p>
  
  <pre><code>    URL url = new URL("http://www.baidu.com");
      HttpURLConnection connection = (HttpURLConnection) url.openConnection();
      connection.setRequestMethod("GET");
      connection.connect();
  
      int code = connection.getResponseCode();
      System.out.println("Response code of the object is " + code);
      if (code == 200) {
          System.out.println("OK");
      }
  </code></pre>
  
  <p>Below is the output:</p>
