Sign multiply

Code:

    @EventHandler
    public void onPlayerInteract(PlayerInteractEvent e) {
        Player p = (Player) e.getPlayer();
        if (e.getAction() == Action.RIGHT_CLICK_BLOCK) {
            if (e.getClickedBlock().getState() instanceof Sign) {
                Sign s = (Sign) e.getClickedBlock().getState();
                for(Signs sign : SignManager.getSigns()) {
                    if(s.getLine(0).equalsIgnoreCase(sign.getLines().get(0))) {
                        if(s.getLine(1).equalsIgnoreCase(sign.getLines().get(1))) {
                            if(s.getLine(2).equalsIgnoreCase(sign.getLines().get(2))) {
                                if(s.getLine(3).equalsIgnoreCase(sign.getLines().get(3))) {
                                    for(String ln : sign.getLines()) {
                                        p.sendMessage("" + sign.getAdd().getType());
                                    }
                                }
                            }
                        }
                    }
                }
            }
        }
    }

Someone knows why when i click on sign i receive 4 messages no one?

 

Because

PHP:

for(String ln : sign.getLines()) {
                                        p.sendMessage("" + sign.getAdd().getType());
                                    }

What this does is for every line on the sign (there are four lines) it sends a message.
4 lines = 4 messages.

 

How can i fix it?

 

Create your string in the for loop (if you want to include all the lines), and then send the message.

 

I can't work out what you are even trying to do to be honest...
