            BukkitObjectOutputStream dataOutput = new BukkitObjectOutputStream(outputStream);
            
            // Write the size of the inventory

            }
            
            // Serialize that array
            dataOutput.close();
            return Base64Coder.encodeLines(outputStream.toByteArray());
        } catch (Exception e) {
            throw new IllegalStateException("Unable to save item stacks.", e);
        }        
    }
    
    public static Inventory fromBase64(String data) throws IOException {
        try {
            ByteArrayInputStream inputStream = new ByteArrayInputStream(Base64Coder.decodeLines(data));
            BukkitObjectInputStream dataInput = new BukkitObjectInputStream(inputStream);
            Inventory inventory = Bukkit.getServer().createInventory(null, dataInput.readInt());
    
            // Read the serialized inventory
            for (int i = 0; i < inventory.getSize(); i++) {
                inventory.setItem(i, (ItemStack) dataInput.readObject());
            }
            dataInput.close();
            return inventory;
        } catch (ClassNotFoundException e) {
            throw new IOException("Unable to decode class type.", e);
        }
    }
}

Its possible to have exemple ?

can i Serialize player inventory?
