How to remove block after certain time rapidly

The title explains everything

What i have so far

Code:

    public void onPlayerMove(PlayerMoveEvent e){
        Player p = e.getPlayer();
        if (!(flashed.contains(p.getName()))){
            return;
        }
       
        if(p.isSprinting() || (!(p.isOnGround()) || still(p))){
            return;
        }
        if(!(p.getItemInHand().hasItemMeta() || p.getItemInHand().getType() == Material.REDSTONE_TORCH_ON )) {
            return;
        }
        Location l = p.getLocation();
        Block bl = l.getBlock();
        try{
            bl.setType(Material.TORCH);
        }catch(Exception ex){
            p.sendMessage(ChatColor.RED + "Couldnt palce down torch - Watch your pace!");
           
        }
        Location old = l.add(0, 0, -2);
        Block o = old.getBlock();
        try{
            o.setType(Material.AIR);
        }catch(Exception ex){
            p.sendMessage(ChatColor.RED + "Couldnt not remove - Watch your pace!");
           
        }

 

What are you asking for? Are you asking for a way to remove all blocks placed down after a certain time? If so, catch the BlockBreakEvent and schedule a repeating task to invoke event.setCancelled(true). Use this resource for help with the scheduler.

 

@JPG2000

If the player is quicker than the scheduler some blocks wont get removed.

Update:
This is what i have now which works perfectly except ..

Code:

    @SuppressWarnings("deprecation")
    @EventHandler
   
   
    public void onPlayerMove(final PlayerMoveEvent e){
        Player p = e.getPlayer();
        if(!(p.getItemInHand().hasItemMeta() || p.getItemInHand().getType() == Material.REDSTONE_TORCH_ON )) {
            return;
        }
        if(e.getFrom().getX() == e.getTo().getX()
                && e.getFrom().getY() == e.getTo().getY()
                && e.getFrom().getZ() == e.getTo().getZ()){
            return;
        }
       
        if(blocks.containsValue(p)){
            for (Entry<Block, Player> entry : blocks.entrySet())
            {
              Block block = entry.getKey();
              Player player = entry.getValue();
              if (player == p)
              {
                  block.setType(Material.AIR);
              }
            }
        }
        if (!(pl.flashed.contains(p.getName())))
        {
            return;
        }
       
        if(p.isSprinting() || (!(p.isOnGround()) || still(p)))
        {
            return;
        }
        Location l = p.getLocation();
        Block bl = l.getBlock();
        try{
            bl.setType(Material.TORCH);
            blocks.put(bl, p);
        }catch(Exception ex){
            p.sendMessage(ChatColor.RED + "Couldnt palce down torch - Watch your pace!");
           
        }

    }

if the player is standing on the edge of a block, it block attempts to place down a torch.
The torch then 'pops' to player inven. How do i stop this and make sure this doesn't happen
