send List<String>

Hi, i would like to do a /help command. The player will get a return from config file within the list "HelpMessages".
All the "Messages" in the list will be send to the player. I would also like to implement color codes.

My current code looks like this:

Code:

public class Help implements CommandExecutor {

    @Override
    public boolean onCommand(CommandSender sender, Command command, String label, String[] args) {
        if(args.length == 0){
            @SuppressWarnings("unchecked")
            List<String> helpmessages = (List<String>)Main.plugin.getConfig().getList("HelpMessages");
            sender.sendMessage(helpmessages);
        }
        sender.sendMessage("Will be added soon");
        return false;
    }

}

And o would like to have my config like this:

PHP:

HelpMessages:
- 'Line1'
- 'Line2'
- 'Should be avalible'
- 'to add how many'
- 'lines you want'

Thank you so much

is this how i should do it?

Code:

@SuppressWarnings("unchecked")
            List<String> helpmessages = (List<String>)Main.plugin.getConfig().getList("HelpMessages");
            String Message = helpmessages.toString();
            sender.sendMessage(Message);

Does it do anything when you run the command?

 

all of the content in the list are added into one line i minecraft.
I want it to be seperated lines i minecraft too...

yes, everything is comming out in one line. What i wanted was on seperated lines

1. Don't cast to List<String>. You can use .getStringList("path") instead of .getList("path")
2. Loop through the list and send the player the message of the current String you are iterating over

There are two ways you can do this. 1:

1. Loop through all the strings, use the methods listed above for color codes, and send each one individually.
2. Create a String field and create a loop for all the strings. Inside that loop you would take the string field, add "\n" (\n means new line) and then the next String.

 

how do i loop through it?

 

@stamline loop through your list of strings and send each message individually with the colors

 

@teej107
but if i have 1000 messages i will send, do i have to make a new "player.sendMessage();" every time?

 

@stamline
If you use the first way that I mentioned, yes. If you use the second way I mentioned (using \n), then you would only need to use the .sendmessage once.

There is .sendMessage(String str) and .sendMessage(String[] str)... so you could just turn that list into an array:

Code:

.sendMessage((String[]) list.toArray());

I think this would be the easiest solution but it won't support color codes. If you want color codes you need to use @Zombie_Striker's or @teej107's answers
