loops

I am trying to solve this for a while, confusing myself more everytime.

i have a custom inv with nothing in it, when the player interacts with an item i can open the gui. I am trying to go through all of the players permissions and only add items based on permissions the player has.

 

Code:

        ItemStack pvp = new ItemStack(Material.DIAMOND_SWORD);

        if (p.getInventory().getItemInMainHand().getType() == Material.BOOK) {
            if (e.getAction() == Action.RIGHT_CLICK_AIR || e.getAction() == Action.RIGHT_CLICK_BLOCK) {
               
                if (p.hasPermission("tkits.pvp")) {
                   
                    kitinv.setItem(0, pvp);
               
                } else {
                   
                    return;
                }
           
           
            p.openInventory(kitinv);
            return;
           
            } else {
               
                return;
            }
        }
        return;
    }
}

@timtower is there a faster way to go through all the perms? or would an else if statement fit this better
