How can I make an event occur when a specific block breaks

I would like to make a summoned block of stone have different properties. How can I make it so that when this block breaks, an event gets triggered? Here is my current code

Code:

package io.github.mysixsenses.helloworld;

import org.bukkit.Location;
import org.bukkit.Material;
import org.bukkit.block.Block;
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{

    boolean check(Command a, String b) {
        return a.getName().equalsIgnoreCase(b);
    }
    boolean checkPlayer(CommandSender player) {
        return player instanceof Player;
    }
    @Override
    public void onEnable() {
        getLogger().info("onEnable has been invoked for the Hello World Plugin!");
    }
  
    @Override
    public void onDisable() {
        getLogger().info("onDisable has been invoked for the Hello World Plugin!");
    }
    //onCommand
    @Override
    public boolean onCommand(CommandSender sender, Command cmd, String label, String[] args) {
        if (check(cmd, "basic")) {// If the player typed /basic then do the following...
            sender.sendMessage("Hello World!");
            return true;
        } else if (check(cmd, "basic2")) {
            if (!(checkPlayer(sender))) {
                sender.sendMessage("This command can only be run by a player.");
            } else {
                Player player = (Player) sender;
                player.sendMessage("Hello World!");
            }
            return true;
        } else if(check(cmd, "summonitem")) {
            if (!(checkPlayer(sender))) {
                sender.sendMessage("This command can only be run by a player.");
            } else {
                Player player = (Player) sender;
                // Get the player's location.
                Location loc = player.getLocation();
                // Sets location to five above where it used to be. Note that this doesn't change the player's position.
                loc.setY(loc.getY() + 5);
                // Gets the block at the new location.
                Block b = loc.getBlock();
                // Sets the block to type id 1 (stone).
                b.setType(Material.STONE);
            }
            return true;
        }
        return false;
    }
}

Currently, my only idea is to add every modified stone into a list with all the stone and check if it's in the modified stone group when OnBlockBreak is called.

@RedKaneChironic Listen to the BlockBreakEvent, then check if the block broken is your specific block.
