Seperating ArrayList items to a regular keyword group

I started Java for plugin codding in minecraft. now I'm trying to add role names as prefix and show it in chat.
ArrayList<String> userRoles = new ArrayList<String>();
if(player.hasPermission("chat.rank.admin")){
userRoles.add("[Admin]");
} if(player.hasPermission("chat.rank.vip")) {
userRoles.add("[VIP]");
}
event.setFormat(userRoles<>(1) + " " + player.getDisplayName() + "§7: " + msg);
// In this line, the expected output is "[Admin] user: msg" or both [Admin] [VIP] user: msg"
// But it gives "([Admin],[VIP]) user: msg"
// I'm sure it has a simple solution but as I said, I'm new here. thanks from now

It seems like you are trying to create a list which only stores one value.
You might want to try creating a function that get the rank name of the player outside of your PlayerChatEvent listener.
Here's a demo code:
public String getPlayerRankName(Player p){
if (p.hasPermission("chat.rank.admin"))
return "[Admin]";
else if (p.hasPermission("chat.rank.vip"))
return "[VIP]";
else
return "";
}
And in your PlayerChatEvent event listener, call this function in your chat line:
event.setFormat(getPlayerRankName(event.getPlayer()) + " " + player.getDisplayName() + "§7: " + msg);

Add reaction in jda to Message by messageid

My problem is, that my code, especially tc.addReactionById(messageID, emote);, dont adds a reaction. The whole code is following!
if(args[0].equalsIgnoreCase(prefix + "system") && args[1].equalsIgnoreCase("radd")){
if(args.length == 6){
Message message = event.getMessage();
List<TextChannel> channels = event.getMessage().getMentionedChannels();
List<Role> roles = message.getMentionedRoles();
if(!channels.isEmpty() && !roles.isEmpty()){
TextChannel tc = event.getMessage().getMentionedChannels().get(0);
Role role = roles.get(0);
String messageIDString = args[2];
try{
long messageID = Long.parseLong(messageIDString);
String emote = args[5];
tc.addReactionById(messageID, emote);
eb.setAuthor("Oni System");
eb.setColor(Color.MAGENTA);
eb.setDescription(emote);
eb.setFooter("Oni System | ©ONI", "https://media.discordapp.net/attachments/810910771557957672/810927512892604416/Bot.png?width=676&height=676");
channel.sendMessage(eb.build()).queue();
LiteSQL.onUpdate("INSERT INTO reactionroles(guildid, channelid, messageid, emoji, roleid) VALUES(" + event.getGuild().getIdLong() + ", " + tc.getIdLong() + ", " + messageID + ", '" + emote +"', " + role.getIdLong() + ")");
} catch (NumberFormatException e) {
e.printStackTrace();
}
}
}
else{
eb.setAuthor("Oni System");
eb.setColor(Color.RED);
eb.setDescription(userMent + " bitte benutze !system radd <messageid> <#role> <channel> <emoji>");
eb.setFooter("Oni System | ©ONI", "https://media.discordapp.net/attachments/810910771557957672/810927512892604416/Bot.png?width=676&height=676");
channel.sendMessage(eb.build()).queue();
}
}

addReactionById is a RestAction in the JDA library, so you will need to queue the operation.
Replace
tc.addReactionById(messageID, emote);
with
tc.addReactionById(messageID, emote).queue();
Assuming the messageID and emote arguments are valid, the call to .queue() should process the reaction. In particular, emote needs to be one of either:
An Emote object created by JDA (usually these are custom server emotes), or
A Unicode string of the emoji you want to add

Bukkit plugin kick reason only using first word

So I'm making a kick/ban command for my server and the format is /kick name reason.
I got it all working but the reason can only be 1 word and anything over that excludes it, for example /kick BattleDash hello world would say BattleDash was kicked for hello.
Here's my code:
if (cmd.getName().equalsIgnoreCase("kick") && sender instanceof Player) {
Player player = (Player) sender;
int length = args.length;
if (length >= 2) {
boolean playerFound = false;
for (Player playerToKick : Bukkit.getServer().getOnlinePlayers()) {
if(playerToKick.getName().equalsIgnoreCase(args[0])) {
playerToKick.kickPlayer(ChatColor.RED + "Kicked by Administrator " + player.getName() + "\nReason: " + args[1]);
player.sendMessage(ChatColor.RED + "[BATTLEDASHLOGS]: Kicked player " + playerToKick.getName() + "succesfully!");
break;
}
}
if (playerFound == false) {
player.sendMessage(ChatColor.RED + "[BATTLEDASHLOGS]: " + args[0] + " was not found!");
}
} else player.sendMessage(ChatColor.RED + "[BATTLEDASHLOGS]: Incorrect arguments!" + ChatColor.RED + " /kick <PlayerName> <reason>");
return true;
}
(Also if you don't include a reason it gives internal error in chat and exception occured in console)

Your code is doing that due to the way it was programmed.
If we take a look at line that takes the argument:
playerToKick.kickPlayer(ChatColor.RED + "Kicked by Administrator " + player.getName() + "\nReason: " + args[1]);
We can see that you're only using args[1]. If we see a message as an array, the problem will be clear:
At position 0 (remember arrays start at 0): BattleDash
1: hello
2: world
When you take only args[1] to your message, only hello would be used! What we need to do instead, is use all the arguments. One way to do that is like this:
// First, transform your array into a list, so it's easier to understand
List<String> arguments = new ArrayList<>(args);
String playerName = arguments.get(0); // Get the player name
arguments.remove(0); // Remove the player name from our arguments list, we don't want it in the message
String message = String.join(" ", arguments); // Combine all the other arguments into a message

getInt Function Doesn't Return Anything

I am currently trying to making a custom rules plugin (for minecraft) and I am trying to see if the player has something activated which I stored in the config file. It is in the listener class (which calls the config from the main). Here is my code:
#EventHandler
public void onEvent(AsyncPlayerChatEvent e) {
Player player = e.getPlayer();
if (config.getInt("EditingLine." + player.getName().toLowerCase()) == 1) {
int line = 0;
try {
line = Integer.parseInt(e.getMessage());
} catch (Exception b) {
player.sendMessage(ChatColor.RED + "Invalid Number.");
config.set("EditingLine." + player.getName().toLowerCase(), 0);
}
if (!(line == 0)) {
config.set("EditingLine." + player.getName().toLowerCase(), 0);
config.set("EditingText." + player.getName().toLowerCase(), 1);
e.setCancelled(true);
player.sendMessage(ChatColor.GRAY + "[" + ChatColor.GOLD + "Custom Rules" + ChatColor.GRAY + "]" + ChatColor.GREEN + " Enter the text you would now like on that line.");
}
}
}
The, config.getInt() function in the if then statement currently returns nothing. This may be happening because the config in the Listener Class is actually calling a custom made config, called 'playerdata.yml' and not the actual 'config.yml'. If there is any easier way to write this script, also let me know. I'm trying to make this as simple as I can.

The answer has been solved by merging my two configuration files together.

Bukkit Coding - Kick message with color codes set in config.yml

So I have a plugin im making where they get kicked with a message. I want that message to be in color that is set in the config.yml. heres my code:
}
if (l == 2) {
settings.getData().set("" + target.getName() + "", null);
settings.saveData();
target.kickPlayer(this.getConfig().getString("BanMessage"));
target.setBanned(true);
Bukkit.getServer().broadcastMessage(ChatColor.RED + target.getName() + " " + "Has been tempbanned for 25 Minutes by " + sender.getName() + "" + "(3/3)");
Bukkit.getServer().getScheduler().scheduleSyncDelayedTask(this, new Runnable() {
public void run() {
target.setBanned(false);
}
}, 1500 * 20);
return true;
}
Heres my config.yml:
BanMessage: You have been temp banned for 25 Minutes

You could use ChatColor.translateAlternateColorCodes():
String kickMessage = plugin.getConfig().getString("BanMessage");
kickMessage = ChatColor.translateAlternateColorCodes('&', kickMessage);
target.kickPlayer(kickMessage);
target.setBanned(true);
You can use these color codes in your configuration file.
So, putting in &6You have been banned for &4Spamming Will give you ChatColor.GOLD + "You have been banned for " + ChatColor.DARK_RED + " Spamming"
and if you would like to make it so they get that same message whenever they join if they're banned, you can use:
#EventHandler
public void playerJoin(PlayerJoinEvent e){
if(myMethodToCheckIfAPlayerIsTempBanned(e.getPlayer()){
String msg = myMethodToGetPlayersBanMessage(e.getPlayer());
e.getPlayer().kickPlayer(msg);
}
}

This should work:
String kickMessage = this.getConfig().getString("BanMessage");
kickMessage.replaceAll("(?i)&([a-f0-9])", "\u00A7$1");
target.kickPlayer(kickMessage);
target.setBanned(true);
Then, you should be able to use these color codes in your config.
ex.
BanMessage: &3You &0have been banned &1for &425 &3minutes
will display as
You have been temp banned for 25 Minutes
