I'm working on a UML diagram using PlantUML to represent a simple ordering system. I’ve written the code, but I’m not sure if it's fully accurate. Could you please take a look and let me know what I can improve or correct?

class Customer {
    - name: String
    - address: String
    + placeOrder(): Order
    + receiveOrder(order: Order): void
}

class Order {
    - orderID: int
    - status: String
    + getStatus(): String
    + setStatus(status: String): void
}

class Owner {
    + confirmOrder(order: Order): void
    + prepareOrder(order: Order): void
}

class DeliveryBiker {
    + pickupOrder(order: Order): void
}

class DeliveryRider {
    + deliverOrder(order: Order): void
}

' Relationships (associations)
Customer "1" -- "1" Order : places
Owner "1" -- "many" Order : confirms and prepares
DeliveryBiker "1" -- "1" Order : picks up
DeliveryRider "1" -- "1" Order : delivers

' Dependencies (methods that use other classes)
Order --|> Customer : references

I’d appreciate any feedback or corrections. Thanks in advance!

I've created a UML diagram using PlantUML to represent a simple ordering system, with classes like Customer, Order, Owner, DeliveryBiker, and DeliveryRider. I’ve tried to define the relationships, methods, and dependencies between the classes, but I’m unsure if the diagram accurately represents the system and if there are any mistakes in the code. I was expecting that this code would render a valid UML diagram with clear class relationships and correct syntax.
