How do I implement a command handler?

I searched for the past few hours on if there are any events for commands.

I would like to just have a simple command that when executed, writes something in chat.

How can I do this?

Is there any built-in event for something like that?

I've seen a few tutorials but they are all from 2012 and dont work anymore.
 

Thanks in advance!

Edit: Sorry if I am being dumb. I just started with minecraft forge. I have a pretty good knowledge of java tho.

Nevermind that haha. I am sorry for being dumb there.

 

But my event isnt registering?

 

@SubscribeEvent
    public void registerCommandsEvent(RegisterCommandsEvent event) {
        LOGGER.info(event);
        LOGGER.info("Test");
        //playerIn.addChatMessage(TextComponent("test"));
    }

Show more of your code. That should work fine.

package com.example.examplemod;

                map(m->m.getMessageSupplier().get()).
                collect(Collectors.toList()));
    }
    // You can use SubscribeEvent and let the Event Bus discover methods to call
    @SubscribeEvent
    public void onServerStarting(FMLServerStartingEvent event) {
        // do something when the server starts
        LOGGER.info("HELLO from server starting");
    }

    @SubscribeEvent
    public void registerCommandsEvent(RegisterCommandsEvent event) {
        LOGGER.info(event);
        LOGGER.info("Test");
        //playerIn.addChatMessage(TextComponent("test"));
    }
}
