Solved How would you send a message to the whole server?

I know this kinda sounds dumb, but how would one send a message to all the players online?
This is how I send a message to a player:

Player player = (Player) sender;
player.sendMessage(ChatColor.RED "test message");

now, how do I do that for the whole server? If I wanted to make a title message to the whole server how can I do that?

 

@RJTech Title message as in /title or chat text message because to do that you can do:
bukkit.broadcastMessage("Text here");

 

The Player class offers a sendTitle method, therefor you have to loop over all online players

 

@cheeseypotato both, mainly the title tho. when I try and add that line, it says i need to make bukkit a variable

 

thk @timtower I should have caught that
