Solved Null pointer with displayname

I have a problem with null pointer.

if(elo[11] != null && elo[15] !=null) {
ItemStack itemek1 = elo[11];
ItemStack itemek2 = elo[15];
if(itemek1.getItemMeta().hasDisplayName() && itemek2.getItemMeta().hasDisplayName()) {
null pointer here ---> if((itemek1.getItemMeta().getDisplayName().contains("§eMagiczna Rózdzka Mocy") || itemek1.getItemMeta().getDisplayName().contains("§1Ognisty Amulet Szybkosci") || itemek1.getItemMeta().getDisplayName().contains("§6Amulet Magicznego Uzdrowienia") || itemek1.getItemMeta().getDisplayName().contains("§2Amulet Boskiej Ochrony") || itemek1.getItemMeta().getDisplayName().contains("§4Amulet Boskiego Swiatla") || itemek1.getItemMeta().getDisplayName().contains("§e§lRóg Obfitosci")) &&(itemek2.getItemMeta().getDisplayName().contains("§eMagiczna Rózdzka Mocy") || itemek2.getItemMeta().getDisplayName().contains("§1Ognisty Amulet Szybkosci") || itemek2.getItemMeta().getDisplayName().contains("§6Amulet Magicznego Uzdrowienia") || itemek2.getItemMeta().getDisplayName().contains("§2Amulet Boskiej Ochrony") || itemek2.getItemMeta().getDisplayName().contains("§4Amulet Boskiego Swiatla") || itemek2.getItemMeta().getDisplayName().contains("§e§lRóg Obfitosci"))) {

 

@Lockiller1996 Try debugging. Also, that looks like quite an if statement, you should probably shorten it for clarity.

 

Ok, I will try debug it. Btw. I don't have any idea how to shorten this statement. How my plugin works: When I put two Items with custom name into GUI slots. They will transform into one item (on GUI close). When I put Items without customname I got null pointer. My statement is so long because I have to check a lot of names of items

 

Oh, I didn't think about it. Good idea.

@timtower I added customnames to list and statement is shorter, but I can't reapir null pointer. Error occured only when I put two items without custom displayname into gui. But when I put only one, everything is okay. Variables "itemek1" and "itemek2" are slots in gui where I'm putting items to transform. variable "nazwy" is a list with customnames (like in the previous long statement). Any idea what is wrong ?

 

@Lockiller1996 you may check if the item has itemMeta first

 

@caderapee I added check for itemMeta and still same error ;/

 

@Lockiller1996 It doesn't seem like the error and code matches, one of them is probably outdated, try posting your current code along with an error caused by your current code.

 

@KarimAKL you are the best Thanks to everyone for help
