Tab Complete Entities

I was wondering how I could tab complete entities. I understand players but can't seem to find entities.
Thanks in advance and I will be here if you don't have all the information needed (this is my first post).

Code:

package com.hatsonboats.commands;

import org.bukkit.Bukkit;
import org.bukkit.command.Command;
import org.bukkit.command.CommandSender;
import org.bukkit.command.TabCompleter;

import java.util.ArrayList;
import java.util.List;

public class InvisTabCompletion implements TabCompleter {
    @Override
    public List<String> onTabComplete(CommandSender sender, Command cmd, String label, String[] args) {
        if(args.length == 1){
            
           
        }
    }
}

 

I mean you wan to tab complete the names of ALL entities? I a not the mosted suited to give advice , but i did this:

Code:java

 
public class TestTabCompleter implements TabCompleter {
 
@Overridepublic List<String> onTabComplete(CommandSender sender, Command cmd, String label, String[] args) {
 
if(!(sender instanceof Player)) { sender.sendMessage(ChatColor.RED + "This command is only for players"); return null;}
Player player = (Player) sender;
List<String> entList = new ArrayList<>(); 
if(cmd.getName().equalsIgnoreCase("spm")) {
 
EntityType[] entArray = EntityType.values();
 
      for(EntityType ent : entArray) {
          entList.add(ent.toString());
      }
 
return (args.length > 0) ? StringUtil.copyPartialMatches(args[0], entList, new ArrayList<>()) : null;}
 
 
 
 
return null;}
}
 

EDIT: Also you dont specify wich command do you want to complete

 

Ok. Its /farm <entity>

Edit: I tried it and it didn't work. I did change spm to farm but it still didnt work

 

Can you post your command class, your main class, and your tab complete class?
