Checking for item lore

How can I check if a player has an item in their inventory and it has a certain lore/display name? I have my custom item created in a different class and now i'm trying to check if a player's inventory contains it in a different class. Here's my code.

Creating the item

Code:

@Sub(permission = "minecraftplanetearth.admin", description = "Get Keep Inventory item", minArgs = 0, allowConsole = true)
    public void getKeepInv(CallInfo call) {
        Player p = call.getPlayer();
        String keepInv = "Keep Inventory";

        List<String> lores = new ArrayList<String>();
        lores.add("Keep this in your inventory");
        lores.add("To keep your items on death");
        lores.add("Will be removed on death");

        ItemStack kI = new ItemStack(Material.DIAMOND);
        ItemMeta im = kI.getItemMeta(); 
        im.setDisplayName(keepInv); 
        im.setLore(lores);
        kI.setItemMeta(im); 
        p.getInventory().addItem(kI);
    }

Checking for item

Code:

@EventHandler
    public void onDeath(PlayerDeathEvent event) {
        Player p = event.getEntity();
        if (event.getKeepInventory() == false) {
            if (p.getInventory().contains(Material.DIAMOND)) {}
        }
      
      
    }

 

Iterate over the current inventory items and check each one for its material (getType()), display name (getItemMeta().getDisplayName()), and lore (getItemMeta().getLore()).
