Bukkit.getOnlinePlayers returns error

I'm new to coding java and I'm attempting to create a custom list based on permissions plugin for an upcoming server of mine, and ran into this;

It seems to be the Bukkit.getOnlinePlayers() is causing the issue, but I'm not sure.

Here's the code and my error log, I've made the part that makes an error, bold and italic.

Code:

package me.vadoxlist;
 
import org.bukkit.Bukkit;
import org.bukkit.command.Command;
import org.bukkit.command.CommandSender;
import org.bukkit.entity.Player;
import org.bukkit.plugin.java.JavaPlugin;
 
public class Main extends JavaPlugin {
 
    public void onEnable() {
        getLogger().info("Plugin enabled!");
    }
 
    public void onDisable() {
        getLogger().info("Plugin disabled!");
    }
 
 
    public boolean onCommand(CommandSender sender, Command cmd, String commandLabel, String[] args) {
        if (cmd.getName().equalsIgnoreCase("list")) {
            Player[] player = [B][I][U]Bukkit.getOnlinePlayers[/U][/I][/B]();
            int admins = 0,owners = 0,mods = 0,users = 0;
            for (int i = 0; i < player.length; i++) {
                if (player[i].hasPermission("BetterList.Admin")) {
                    admins++;
                } else if (player[i].hasPermission("BetterList.Moderator")) {
                    mods++;
                } else if (player[i].hasPermission("BetterList.Owner")) {
                    owners++;
                }
                else {
                    users++;
                }
            }
            sender.sendMessage("----------------------------");
            sender.sendMessage("Players ("+""+users+"/"+Bukkit.getServer().getMaxPlayers()+") Online");
            sender.sendMessage("Admins: ("+admins+") Online");
            sender.sendMessage("Moderators: ("+mods+") Online");
            sender.sendMessage("Owners: ("+owners+") Online");
            sender.sendMessage("----------------------------");
        }
        return true;
    }
}

When I hover over the Bukkit.getOnlinePlayers() in eclipse it shows:
" Type mismatch: cannot convert from Collection<capture#1-of ? extends Player> to Player[]"

Error log (from console log):

All and any help is appreciated!

 

Derugo CraftBukkit changed the return type of Bukkit.getOnlinePlayers() from a Player[] to a Collection<? extends Player>. Just change this in your code.

 

It returns a collection, not an array.

I've tried this, but it seems to break everything else, well, part of it, here's the code after with the errors:

Derugo instead of indexing it yourself, why don't you change it to a foreach loop

Code:

for(Player player : Bukkit.getOnlinePlayers())
{
    // TODO: something with the player
} 

 

How would I go about doing this?
Doing it for each of the groups, users, moderators, admins, owners, etc?

 

Derugo in that printscreen you posted, it would just be changing player[ i] to player (and the for loop to a foreach as shown in my previous snippet)

 

Not sure if this is right but no more errors except for a new error with player.lengh:
http://prntscr.com/4cmu3q

 

Derugo because you kept your old code and wrapped it in a for loop... First declare the int values 'owners', 'admins', 'mods' and 'users', then loop over the players using

And in the loop you do the if-statements

 

Completely puzzled with what you're telling me to do. Any chance you could show an example of what you mean for one of the int values?

 

Derugo read Java documentation and tutorials about how Java collections and loops work.
