Error when armor not specified in config

This is my code:

Code:

    @SuppressWarnings("deprecation")
    public void giveArmor(Player p, Block b) {
        Sign sign = (Sign) b.getState();
        String two = ChatColor.stripColor(sign.getLine(1));
        String[] armor = plugin.getConfig().getString("Classes." + two + ".Armor").split(",");
        if (armor != null) {
            if (Integer.parseInt(armor[0]) != 0) {
                p.getInventory().setHelmet(new ItemStack(Integer.parseInt(armor[0]), 1));
                p.updateInventory();
            }
            if (Integer.parseInt(armor[1]) != 0) {
                p.getInventory().setChestplate(new ItemStack(Integer.parseInt(armor[1]), 1));
                p.updateInventory();
            }
            if (Integer.parseInt(armor[2]) != 0) {
                p.getInventory().setLeggings(new ItemStack(Integer.parseInt(armor[2]), 1));
                p.updateInventory();
            }
            if (Integer.parseInt(armor[3]) != 0) {
                p.getInventory().setBoots(new ItemStack(Integer.parseInt(armor[3]), 1));
                p.updateInventory();
            }
        }
    }

If armor is not in the config then it gives me this error:

I've done if (armor != null) { however I still get the error
It's this line: String[] armor = plugin.getConfig().getString("Classes." + two + ".Armor").split(",");
Anyone know how to stop or fix this?
Thanks

 

The getString(...) throws the NullPointerException because the path in the config doesn't exist.
Add a default value to your getString(...), then the plugin will use that when it can't find the path.

 

Is this the line you've posted?

Edit: Derp. I think sd5 is right. I have the dumb today.
