Development Assistance How to get the color of a banner?

Please ignore my spelling mistakes , the used translator.

I tried to get the color of the flag,I've done this with: " DyeColor color = ((BannerMeta)e.getClickedBlock().getState()).getBaseColor(); " but I can still make it work.

My code:

Code:

public void onPlayerInteract(PlayerInteractEvent e) {
        final Player p = e.getPlayer();
        if(e.getClickedBlock().getType() == Material.STANDING_BANNER) {
            DyeColor color = ((BannerMeta)e.getClickedBlock().getState()).getBaseColor(); /* < ERROR */
            if(color == DyeColor.BLUE) /* < ERROR */
            {
                Block sb = e.getClickedBlock();
                ItemStack B1 = new ItemStack(Material.BANNER);
                BannerMeta B1M = (BannerMeta)B1.getItemMeta();
                B1M.setDisplayName(ChatColor.BLUE + "" + ChatColor.BOLD + "Black");
                B1M.setBaseColor(DyeColor.BLUE);
                B1.setItemMeta(B1M);
                final ArmorStand stand = p.getWorld().spawn(p.getLocation(), ArmorStand.class);
                stand.setBasePlate(false);  
                stand.setVisible(false);
                stand.setGravity(false);
                stand.setArms(false);
                stand.setRemoveWhenFarAway(false);
                stand.setCustomNameVisible(true);
                stand.setHelmet(B1);
                sb.setType(Material.AIR);
                p.sendMessage(ChatColor.BLUE + " Flag in your head! ");
                getServer().getScheduler().scheduleSyncRepeatingTask(this, new Runnable(){
                    public void run() {
                        Location standloc = p.getLocation();
                        int x = standloc.getBlockX();
                        int y = standloc.getBlockY();
                        int z = standloc.getBlockZ();
                        Location standlocnew = new Location(p.getWorld(), x + 0.5, y, z + 0.5);
                        standlocnew.setYaw(p.getLocation().getYaw());
                        standlocnew.setPitch(p.getLocation().getPitch());
                        stand.setCustomName(ChatColor.BLUE + " Blue Flag ");
                        stand.teleport(standlocnew);
                       
                    }
                }, (long) (0.1), (long) (0.1));
            }
            else {
                p.sendMessage(ChatColor.RED + " Its your flag! ");
            }
          }
           
       
    }

 

What exactly is the stacktrace error that idenfies that line? Null Pointer Exception? Index out of Bounds? Unable to cast object error?

 

@Boomer
I did not want to refer to that line is wrong.
The line does not throw any errors , but running the event in the game. The error is generated
I changed the code a bit , but still does not work ...
I will show my throwing error by clicking on the banner.
My new code:

Code:

@EventHandler
    public void onPlayerInteract(PlayerInteractEvent e) {
        final Player p = e.getPlayer();
        if(e.getClickedBlock().getType() == Material.STANDING_BANNER) {
                Block sb = e.getClickedBlock();
                BannerMeta B1B = (BannerMeta)sb.getState();
                if(B1B.getBaseColor() == DyeColor.BLUE) {
                     ItemStack B1 = new ItemStack(Material.BANNER);
                        BannerMeta B1M = (BannerMeta)B1.getItemMeta();
                        B1M.setDisplayName(ChatColor.BLUE + "" + ChatColor.BOLD + "Black");
                        B1M.setBaseColor(DyeColor.BLUE);
                        B1.setItemMeta(B1M);
                        final ArmorStand stand = p.getWorld().spawn(p.getLocation(), ArmorStand.class);
                        stand.setBasePlate(false); 
                        stand.setVisible(true);
                        stand.setGravity(false);
                        stand.setArms(false);
                        stand.setRemoveWhenFarAway(false);
                        stand.setCustomNameVisible(true);
                        stand.setHelmet(B1);
                        sb.setType(Material.AIR);
                        p.sendMessage(ChatColor.BLUE + " Flag in your head! ");
                        getServer().getScheduler().scheduleSyncRepeatingTask(this, new Runnable(){
                            public void run() {
                                Location standloc = p.getLocation();
                                int x = standloc.getBlockX();
                                int y = standloc.getBlockY();
                                int z = standloc.getBlockZ();
                                Location standlocnew = new Location(p.getWorld(), x + 0.5, y, z + 0.5);
                                standlocnew.setYaw(p.getLocation().getYaw());
                                standlocnew.setPitch(p.getLocation().getPitch());
                                stand.setCustomName(ChatColor.BLUE + " Blue Flag ");
                                stand.teleport(standlocnew);
                              
                            }
                        }, (long) (0.1), (long) (0.1));
                }
                else {
                    p.sendMessage(ChatColor.RED + " Its your flag! ");
            }
          
          
          }
          
      
    }
