title: Refreshing counter in jLabel
body: <p>Is there any way to refresh the counter in jLabel when a button
   is on click? I tried with repaint(), revalidate() methods already but all does not work. </p>
  
  <p>When like button is on click : </p>
  
  <pre><code>    jButton_like.addActionListener(new java.awt.event.ActionListener() {
              public void actionPerformed(java.awt.event.ActionEvent e) {
                  int count = 1;
                  eForumLikeCounter likeAmount = new eForumLikeCounter(
                          userName, topicId, count);
                  if (likeAmount.checkLikeAmount() == true) {
                      JOptionPane
                              .showMessageDialog(null,
                                      "Unable to perform like on the same thread by the same user");
                  } else if (likeAmount.checkDislikeExists() == true) {
                      JOptionPane
                              .showMessageDialog(null,
                                      "You can only either like or dislike this thread");
                  } else {
                      likeAmount.likeCounter();
                  }
              }
          });
      }
  </code></pre>
  
  <p>Set up for database : </p>
  
  <pre><code>    public void SetUpLikeDislikeAmount() {
      int likes = 0;
      int dislike = 0;
      // Set Up Database Source
      db.setUp("IT Innovation Project");
      String sql = "Select likeDislike_likes,likeDislike_dislike from forumLikeDislike WHERE likeDislike_topics = "
              + topicId + "";
      ResultSet resultSet = null;
      // Call readRequest to get the result
      resultSet = db.readRequest(sql);
      try {
          while (resultSet.next()) {
              likes += resultSet.getInt("likeDislike_likes");
              dislike += resultSet.getInt("likeDislike_dislike");
          }
          resultSet.close();
      } catch (Exception e) {
          System.out.println(e);
      }
      jLabel_like.setText(Integer.toString(likes));
      jLabel_dislike.setText(Integer.toString(dislike));
  }
