title: Using an array of jFrames?
body: <p>I want to make a popup box where in each box there is a different message. I do not know the number of messages. I want to know what would be the best way to display those jFrames. I have  used an array where the length of the array is the number of messages. The problem is that I am getting a NullPointerExeption. What am I doing wrong?</p>
  
  <pre><code>    public void interpret() {
      String[] command = html.split(";");
  
      for (int i = 0; i &lt; command.length; i++) {
          //  System.out.println(command[i]);
          if (command[i].contains("message")) {
              showMessage(command[i].substring(8, command[i].length() - 1));
          }
      }
  
  
  
  }
  messagePopUp[] mes = new messagePopUp[10]; // I am just using length 10 for debugging
  
  private void showMessage(String line) {
  
      mes[0].setTextAlert(line); // line giving me the error
      mes[0].setVisible(true);
  
  }
  </code></pre>
  
  <p>The messagePopUp.class is just a default jPanel class which I have added the setTextAlert();</p>
  
  <p>Thank you</p>
