Bukkit.getConsoleSender().sendMessage("Hello, console!");
for (Player player : Bukkit.getServer().getOnlinePlayers()) { player.sendMessage("Hello, online players!"); }This code sends the message "Hello, online players!" to all players currently online on the server. It uses the Bukkit.getServer() method to get the server object, and then calls the getOnlinePlayers method to retrieve a list of all online players. It then loops through the list and sends the message to each player using the player.sendMessage method. Overall, the org.bukkit package is used to develop plugins for Minecraft servers in Java. The Bukkit class contains various methods for interacting with the server, including the getConsoleSender method for sending messages to the console.
