Solved Replacing broken block into a new block

Hi, im trying to set the broken block to bedrock before replacing it again to the broken block type, I cant figure out a way to get it working..

Code:

public class BlockBreakEvent implements Listener {

    private Main main;
    private HashMap<Location, Block> brokenBlock = new HashMap<Location, Block>();

    public BlockBreakEvent(Main main) {
        this.main = main;
    }

    @EventHandler
    public void blockBreak(org.bukkit.event.block.BlockBreakEvent event) {
        Player player = event.getPlayer();
        PlayerLevelManager playerLevelManager = main.levelManagerHashMap.get(player.getUniqueId());
        Location location = event.getBlock().getLocation();
        Block block = event.getBlock();
        brokenBlock.put(location, block);
        if (block.getType() == Material.COBBLESTONE) {
            event.getBlock().setType(Material.BEDROCK);
            player.getInventory().addItem(new ItemStack(Material.COBBLESTONE,1 ));
            Bukkit.getScheduler().runTaskLater(main, new Runnable() {
                @Override
                public void run() {
                    event.getBlock().setType(Material.COBBLESTONE);
                    brokenBlock.clear();
                }
            }, 200);
        }
        //SCOREBOARD
        playerLevelManager.setXp(playerLevelManager.getXp() + 100);
        player.sendMessage("§a[!] +100 esperienza");
        main.xpCheck(player, playerLevelManager);
        ScoreboardManager scoreboardManager = new ScoreboardManager(main);
        scoreboardManager.setScore(player, playerLevelManager.getLevel(), playerLevelManager.getXp());
    }
}

 

Oh im sorry it all works fine but it doesn't replace the broken block with bedrock... anyways thanks for replying and the advice!
