Writing User Input to file

Hey... Im trying to get user input and put it in a new line in a file... Im having heaps of trouble.

/post <message that needs to be put on file>

idk how to do it D;

Could someone help me with this please?

 

Code:

    public static void writeToFile(String fileName, String bulletin, Player player) throws IOException {
        FileWriter writer = new FileWriter("plugins/BulletinNextDoor/" + fileName, true);
 
            writer.write("\n" + bulletin);
            writer.close();
    }

This is a cut down version of what i use to write messages to a file, all you need is the message to put in, in which i would recommend you look up on how to use a string builder for. This method also assumes the file exists first btw.

 

How would I create the file? Also whats a string builder

 

I use a userdata.yml for some of my plugins, and the methods I use to get/load/save it were taken from here (BukkitWiki) and here (WalkerCrouse's tutorial)

Here I put the methods I use together into one nifty copy&paste-able piece of code.

(It contains 2 constants, and 4 methods to handle a "non-config" yml file)

But I still don't know how to put the user input with a command(/post <message>) into a file...

 

Code:

String msg;
StringBuilder sb = new StringBuilder();
for (int i = 0; i < args.length; i++) {
    if (i != 0)
    sb.append(' ');
    sb.append(args[i]);
}
msg = sb.toString();

That is the message if its used in a command, which i assume it is.

 

How do I make the actual command?

 

Well i recommend you look on some tutorials, but here is something to get you started.

Code:

    @Override
    public boolean onCommand(CommandSender sender, Command cmd, String label, String[] args) {
        if (cmd.getName().equalsIgnoreCase("post")) {
            if (sender instanceof Player) {
                if (args.length == 0) {
                    sender.sendMessage("You muppet");
                }
 
                Player bsender = (Player) sender;
 
                StringBuilder sb = new StringBuilder();
                for (int i = 0; i < args.length; i++) {
                    if (i != 0)
                        sb.append(' ');
                    sb.append(args[i]);
                }
                msg = sb.toString();
           
                Bukkit.getServer().broadcastMessage(msg);
        }
    }
}
