Solved NullPointer

Hi, i get NullPointerException in this string:

Code:

 plugin.Death.replace(killer.getName(), plugin.Death.get(player.getName() + 1)); 

HashMap Death:

Code:

 HashMap<String, Integer> Death = new HashMap<String, Integer>(); 

Constructor:

Code:

 
    private KitPVP plugin;
    public Handler(KitPVP plugin) {
        this.plugin = plugin;
    }

 

I would say there is a mistake with the brackets it should be

Code:

 [...]player.getName()) + 1);

Or am i wrong?

 

I redid the brackets but the error was not corrected, you wrong.

 

Then please post the whole listener

 

I use player name in hashmap

        kits.setItemMeta(kmeta);
        mmeta.setDisplayName(ChatColor.YELLOW + "" + ChatColor.BOLD + "Магазин наборов");
        magaz.setItemMeta(mmeta);
        p.getInventory().setItem(0, kits);
        p.getInventory().setItem(1, magaz);
        return; 
    }

}

 

p.getCustomName might return null. If you work with player names just use p.getName() (or just store the player object)

 

I try to store player obj and its work, thanks.
Solved.
