The next method that we will create is an EventHandler. We use the @EventHandler annotation to tell Bukkit which of our methods are event listeners. Create a new method that has our event of choice as the only parameter. The method must be public and it should not return anything. You may name this method anything you wish to, but most programmers will keep the name similar to the name of the event. The following code is an example of the method header:
