I don't know how the <StringUtil.copyPartialMatches()> Works

I are try making a auto complete for my commando of plugin, but I stuck in this comand:

Code:

StringUtil.copyPartialMatches ()

This fuction have a red underscore, thats means I dont know how work and how use it.

How i can solve this? And have a alternative form to make auto compleate for my command with out API or external classes.

My full code:

@main CLASS FILE

Code:Java

//Import Class
import net.makenoise.*;
 
//Inside of public Class....
getCommand("makenoiseCompleter").setTabCompleter(new makenoiseCompleter());
 

@Compleater Class

Code:Java

package net.makenoise;
 
//Syntax=Java Utils
import Syntax=Java.util.ArrayList;
import Syntax=Java.util.Collections;
import Syntax=Java.util.List;
 
//Bukkit
import org.bukkit.command.Command;
import org.bukkit.command.CommandSender;
import org.bukkit.command.TabCompleater;
import org.bukkit.util.StringUtil;
 
public class makenoiseCompleter implements TabCompleter{
 
    private static final String[] COMMANDS = {"enderman","creeper","zombie","spider"};
 
    @Override
    public List<String> onTabComplete(COmmandSender sender, Command command, String label, String[] args){
 
        final List<String> completions = new ArrayList<>();
 
        StringUtil.copyPartialMatches(args[0], COMMANDS, completions);
 
        Collection.sort(completions);
 
        return completions;
 
 
    }
 
 
}

1. There's no need for you to sort the list, it's already done before the player sees it.
2. Just do something like this:

Code:Java

String[] yourFirstArguments = new String[] {"test", "123", "lol"};
String[] yourSecondArguments = new String[] {"still", "a", "test"};
 
List<String> list = new ArrayList<>();
 
if (args.length == 1) {
    for (String string : yourFirstArguments) if (string.toLowerCase().startsWith(args[0].toLowerCase())) list.add(string);
} else if (args.length == 2) {
    if (args[0].equalsIgnoreCase("yourFirstArgument")) {
        for (String string : yourSecondArguments) if (string.toLowerCase().startsWith(args[1].toLowerCase())) list.add(string);
    }
}
return list;

You should be able to guess the rest yourself.

 

Now thats make a lot more sense to me ... Thanks to help me to finde how to solve this case...
