Solved Share ArrayList data between classes?

So, i'm working on a plugin but a problem came up, i need to have 1 class add/remove players from an ArrayList and another class to read it.

Example:

Main.java:

Code:java

import java.util.ArrayList;
 
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 {
 
    ArrayList<Player> godmode = new ArrayList<>();
 
    @Override
    public void onEnable() {
        getServer().getPluginManager().registerEvents(new PlayerDamageListener(), this);
    }
 
    @Override
    public boolean onCommand(CommandSender sender, Command command,
            String label, String[] args) {
        if (command.getName().equalsIgnoreCase("godmode")) {
            if (sender instanceof Player) {
                Player player = (Player) sender;
                if (!(godmode.contains(player))) {
                    godmode.add(player);
                    player.sendMessage("GODMODE ON");
                } else {
                    godmode.remove(player);
                    player.sendMessage("GODMODE OFF");
                }
            }
        }
        return false;
    }
 
}

PlayerDamageListener:

Code:java

import org.bukkit.entity.Player;
import org.bukkit.event.EventHandler;
import org.bukkit.event.Listener;
import org.bukkit.event.entity.EntityDamageEvent;
 
public class PlayerDamageListener implements Listener {
 
    Main m = new Main();
 
    @EventHandler
    public void onPlayerDamage(EntityDamageEvent event) {
        if (event.getEntity() instanceof Player) {
            Player player = (Player) event.getEntity();
            if (m.godmode.contains(player)) {
                event.setCancelled(true);
            }
        }
    }
 
}

I'm getting no errors, it just gets an empty List...

Thanks

You can access it by just

Code:java

Main.godmode

or you could add a getter and setter in your Main class:

Getter (open) Getter (close)

Code:java

public ArrayList<Player> getGodmode(){
    return godmode;
}

Setter (open) Setter (close)

Code:java

public void setGodmode(Player player, boolean add){
    if (add)
        godmode.add(player);
    else
        godmode.remove(player);
}

I just tested this, i changed my ArrayLists to static and now it works PERFECTLY!
Thanks, man!
