    Default Java IRC Bot

    Alright, so I am getting the messages perfectly from the Twitch Server, but when I go to section them off the bot crashes. This is the code I read the messages from, and this is very important to myself in order to make the bot function dynamically.

    public static void handleLine(String line) throws IOException {
         if (line == null) {throw new IllegalArgumentException("Can't process null line");}
              while ((line = in.readLine()) != null) {
    	       log("<<<" + line);
    	       if (line.startsWith("PING")) {
    	            sendRawLine(line.replace("PING", "PONG"));
    	       }
                   String[] args = line.split(":");
    	       String command = args[2]; // Line where it goes wrong.
                   if(command.contains("test")) {
    	            sendMessage("#peacebot","testing");
    	       }
    	  }
         }
    }

    I would appreciate it if anyone could help me with this, because I am rather new to Java but I am not new to IRC.

    Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: 2
    at me.mretech.peacebot.peacebot.handleLine(peacebot.j ava:46)
    At line 46 the code uses an index (2) that is past the end of the array. The code should test the length of the array before trying to use an index past the end of the array.
