Solved HashMap empty after putting

So,
I've been trying to create a quarry plugin.
And I've ran into an issue.

After I call QuarryBlockBreaks.put(somelocation)
It reports (console) that the size is one
And then after I wait for the loop, it always reports size 0.

QuarryPlaceEvent (BlockPlaceEvent):

Code:

package Quarry;

import org.bukkit.event.EventHandler;
import org.bukkit.event.Listener;
import org.bukkit.event.block.BlockPlaceEvent;

public class QuarryPlaceEvent implements Listener {

    @EventHandler
    public void onBlockPlace(BlockPlaceEvent e) {
        if(!e.getItemInHand().getItemMeta().getDisplayName().equals((new QuarryItem()).Get(1).getItemMeta().getDisplayName())) { e.getPlayer().sendMessage("no"); return; }
        QuarryBlockBreaks handler = new QuarryBlockBreaks();
        handler.put(e.getBlock().getLocation());
        e.getPlayer().sendMessage((new QuarryItem()).Get(1).getItemMeta().getDisplayName() + " placed");
    }
}

QuarryBlockBreaks (The actual breaking mechanism):

Code:

package Quarry;

import org.bukkit.*;
import org.bukkit.block.Block;
import org.bukkit.command.ConsoleCommandSender;
import org.bukkit.inventory.ItemStack;

import java.util.HashMap;

public class QuarryBlockBreaks {
    public HashMap<Location, Object[]> Quarries = new HashMap<>();
    public ConsoleCommandSender s = (Main.getPlugin(Main.class)).getServer().getConsoleSender();
    public void onServerStart() {
        s.sendRawMessage("a");
        Bukkit.getScheduler().scheduleSyncRepeatingTask((Main.getPlugin(Main.class)), () -> {
            s.sendRawMessage("r " + Quarries.size());
            for(Object[] Quarriesv: Quarries.values()) {
                s.sendRawMessage("inside of for");
                Location qLocation = (Location) Quarriesv[0];
                int x = (int) qLocation.getX();
                int z = (int) qLocation.getZ();
                World qWorld = qLocation.getWorld();
                int CurrentY = (int) Quarriesv[1];
                s.sendRawMessage("past setting values");
                if(qWorld.getBlockAt(x, CurrentY-1, z).getType() != Material.BEDROCK) {
                    s.sendRawMessage("!bedrock");
                    CurrentY--;
                    Block CurrentBlock = qWorld.getBlockAt(x, CurrentY, z);
                    if(CurrentBlock.isLiquid() || CurrentBlock.isEmpty()) {
                        s.sendRawMessage("liquid / empty");
                        CurrentBlock.setType(Material.AIR);
                    } else {
                        s.sendRawMessage("!liquid / !empty");
                        qWorld.dropItemNaturally(new Location(qWorld, x, CurrentY, z), new ItemStack(qWorld.getBlockAt(x, CurrentY, z).getType(), 1));
                    }
                    s.sendRawMessage("about to replace " + Quarries.size());
                    Quarries.replace(qLocation, new Object[] {
                            qLocation,
                            CurrentY
                    });
                    s.sendRawMessage("after replacing" + Quarries.size());
                } else {
                    qWorld.getBlockAt(qLocation).setType(Material.AIR);
                    qWorld.dropItemNaturally(qLocation, (new QuarryItem()).Get(1));
                    s.sendRawMessage("removing quarry @ " + qLocation.getX() + " " + qLocation.getY() + " " + qLocation.getZ());
                    Quarries.remove(qLocation);
                }
            }
        }, 0L, 20L);
    }
    public void put(Location l) {
        Quarries.put(l, new Object[]{
                l,
                l.getY()
        });
        s.sendRawMessage("put");
        s.sendRawMessage(Integer.toString(Quarries.size()));
    }
}

And after I place the quarry, in console is says:

 

I'm sorry but I don't understand...

 

Sorry, but I'm a bit new to Java so idk how to do this, tried googling it, but it came up with a weird thing that I don't understand.

 

I put the onBlockPlace event in QuarryBlockBreaks, registered it, and tested it, and it seems like it's... putting but the loop always says it's 0

Code now:

Code:

package Quarry;

import org.bukkit.*;
import org.bukkit.block.Block;
import org.bukkit.command.ConsoleCommandSender;
import org.bukkit.event.EventHandler;
import org.bukkit.event.Listener;
import org.bukkit.event.block.BlockPlaceEvent;
import org.bukkit.inventory.ItemStack;

import java.util.HashMap;

public class QuarryBlockBreaks implements Listener {
    public HashMap<Location, Object[]> Quarries = new HashMap<>();
    public ConsoleCommandSender s = (Main.getPlugin(Main.class)).getServer().getConsoleSender();
    public void onServerStart() {
        s.sendRawMessage("a");
        Bukkit.getScheduler().scheduleSyncRepeatingTask((Main.getPlugin(Main.class)), () -> {
            s.sendRawMessage("r " + Quarries.size());
            for(Object[] Quarriesv: Quarries.values()) {
                s.sendRawMessage("inside of for");
                Location qLocation = (Location) Quarriesv[0];
                int x = (int) qLocation.getX();
                int z = (int) qLocation.getZ();
                World qWorld = qLocation.getWorld();
                int CurrentY = (int) Quarriesv[1];
                s.sendRawMessage("past setting values");
                if(qWorld.getBlockAt(x, CurrentY-1, z).getType() != Material.BEDROCK) {
                    s.sendRawMessage("!bedrock");
                    CurrentY--;
                    Block CurrentBlock = qWorld.getBlockAt(x, CurrentY, z);
                    if(CurrentBlock.isLiquid() || CurrentBlock.isEmpty()) {
                        s.sendRawMessage("liquid / empty");
                        CurrentBlock.setType(Material.AIR);
                    } else {
                        s.sendRawMessage("!liquid / !empty");
                        qWorld.dropItemNaturally(new Location(qWorld, x, CurrentY, z), new ItemStack(qWorld.getBlockAt(x, CurrentY, z).getType(), 1));
                    }
                    s.sendRawMessage("about to replace " + Quarries.size());
                    Quarries.replace(qLocation, new Object[] {
                            qLocation,
                            CurrentY
                    });
                    s.sendRawMessage("after replacing" + Quarries.size());
                } else {
                    qWorld.getBlockAt(qLocation).setType(Material.AIR);
                    qWorld.dropItemNaturally(qLocation, (new QuarryItem()).Get(1));
                    s.sendRawMessage("removing quarry @ " + qLocation.getX() + " " + qLocation.getY() + " " + qLocation.getZ());
                    Quarries.remove(qLocation);
                }
            }
        }, 0L, 20L);
    }

    @EventHandler
    public void onBlockPlace(BlockPlaceEvent e) {
        if(!e.getItemInHand().getItemMeta().getDisplayName().equals((new QuarryItem()).Get(1).getItemMeta().getDisplayName())) { e.getPlayer().sendMessage("no"); return; }
        s.sendRawMessage(Quarries.size() + "s");
        Quarries.put(e.getBlock().getLocation(), new Object[] {
                e.getBlock().getLocation(),
                e.getBlock().getLocation().getY()
        });
        s.sendRawMessage(Quarries.size() + "z");
        e.getPlayer().sendMessage((new QuarryItem()).Get(1).getItemMeta().getDisplayName() + " placed");
    }
}

Console output:

Main:

Code:

package Quarry;

import org.bukkit.plugin.java.JavaPlugin;

public class Main extends JavaPlugin {
    @Override
    public void onEnable() {
        getCommand("quarry").setExecutor(new QuarryCommand());
        getServer().getPluginManager().registerEvents(new QuarryBlockBreaks(), this);
        (new QuarryBlockBreaks()).onServerStart();
        s(true);
    }

    @Override
    public void onDisable() {
        s(false);
    }

    private void s(boolean S) { getServer().getConsoleSender().sendRawMessage(getName() + " has been " + (S? "enabled" : "disabled")); }
}

 

I edited the previous message to include Main to avoid double-posting.

 

Ok, it works now. Thanks!
