Solved Can someone tell me why this isn't working.

I have an error in my PlayerJoinEvent. I have been stuck on it for while and can't figure out exactly why it isn't working. Any help would be appreciated.
This is my code:

Code:java

package com.itscane.minerp;
 
import java.io.IOException;
 
import org.bukkit.Bukkit;
import org.bukkit.ChatColor;
import org.bukkit.entity.Player;
import org.bukkit.event.EventHandler;
import org.bukkit.event.Listener;
import org.bukkit.event.player.PlayerJoinEvent;
import org.bukkit.scheduler.BukkitRunnable;
 
public class Event implements Listener {
 
public Main main;
 
@EventHandler
public void join(PlayerJoinEvent e) {
 
final Player p = e.getPlayer();
 
if (main.players.contains(p.getName())) {
 
double a = main.config.getDouble("StartingMoney");
main.players.set(p.getName() + ".Wallet", a);
main.players.set(p.getName() + ".Bank", 0);
try {
main.players.save(main.playersFile);
} catch (IOException e1) {
e1.printStackTrace();
}
p.sendMessage(ChatColor.BLUE
+ "This server is running MineRP by ItsCane and Mark_Laymon");
p.sendMessage(ChatColor.BLUE
+ "Your account was created and $100 was added to your account!");
p.sendMessage(ChatColor.BLUE
+ "To prevent losing some of your money on death, deposit money into your bank.");
p.sendMessage(ChatColor.BLUE
+ "You need to have your money on you to buy things!");
 
} else {
p.sendMessage(ChatColor.BLUE + "Welcome back!");
p.sendMessage(ChatColor.BLUE
+ "This server is running MineRP by ItsCane and Mark_Laymon");
}
}
 
}
 

This is my console error:

Thanks ahead.

 

I'm going to guess the Main variable is null. You'll need to set it in a constructor.

 

That was it. Thanks.
