Getting Armor Back from File

I'm using (@KingFaris11)'s method of saving and getting inventories with files. Here is a link to the page:

https://forums.bukkit.org/threads/util-saving-getting-inventories-from-a-file.164145/

I was able to figure out how to save a player's armor to the data file, but I am unable to figure out how to get it back from the file. Here is the code that I am currently using:

Code:

            if (alias.equalsIgnoreCase("iload")) {
                Inventory playerInventory = (Test.getInventoryFromFile(new File(this.getDataFolder(), "inv.invsave")));
                ItemStack[] contents = playerInventory.getContents();
                ItemStack[] armcontents = ((PlayerInventory) playerInventory).getArmorContents();
                if (armcontents != null) player.getInventory().setArmorContents(armcontents);
                if (contents != null) player.getInventory().setContents(contents);
                    player.sendMessage("Inventory loaded!");
            }

This, however, creates an error in the console and does not load the armor. Also, in the line

Code:

ItemStack[] armcontents = ((PlayerInventory) playerInventory).getArmorContents();

I have to add the cast "(PlayerInventory)" which I believe is causing the error. Here is the error that is sent to console:

Code:

What I am trying to figure out, is how to get the armor back from the file and give it directly to the player in the armor slots. Any help would be appreciated.

 

Bump.

 

Show us the other classes used, you used the class "Test" I may be able to help if you show us it?

 

In line 172 there is a null variable causing null pointer exception. We might find it and help you solve it if you do what yewtree8 told you
