Help me to code my first plugin

Hi guys,
I working on my first Minecraft plugin.
Now, I search the code, to send a global message. So that all the players on the Server can see the message. Like is't a normal message sent by a player / console.
I'm using this thread to post more than one question, so be active

What is your question.

Ironic how your question isn't grammatically a question, haha. Just kidding.

Okay, from what I understand what sacha220899, you want to code a plugin that sends a message to everyone online?

Code:

for (Player player : Bukkit.getOnlinePlayers()) {
player.sendMessage("Hello!");
}

That's how, basically you get everyone online and cast it to the variable "player". Then you send a message to them.

Ok, wan't to code a plugin named "true or false"
I have coded the tpall to a point, sounds, permissions and the messages. Now I have to code the mute thing, but I don't know how :/ I know that I have to cancel the AsyncPlayerChatEvent, but I don't know how to do this easy. I want it, that I can mute the chat with /globalmute, and than, I will code it in with the executeCommand(globalmute).
And I have to code a countdown. So that the numbers appears in the chat: 30sek... (break of 10 seconds) 20sek... (break) 10sek...9sek...8sek.. etc. How can I do this?
