// Define the state interface
interface OrderState {
    void processPayment();
    void prepareOrder();
    void shipOrder();
}

// Concrete state classes
class OrderPendingState implements OrderState {
    @Override
    public void processPayment() {
        // Logic for processing payment
        // Transition to the In Progress state
        order.setState(new OrderInProgressState(order));
    }
    
    // Other methods
}

class OrderInProgressState implements OrderState {
    // Implement methods for In Progress state
}

class OrderShippedState implements OrderState {
    // Implement methods for Shipped state
}

// Context class
class Order {
    private OrderState state;

    public Order() {
        // Initialize with the Pending state
        state = new OrderPendingState(this);
    }

    public void setState(OrderState state) {
        this.state = state;
    }

    public void processPayment() {
        state.processPayment();
    }

    // Other order-related methods
}

// Usage
Order order = new Order();
order.processPayment(); // This will transition to In Progress state
order.prepareOrder();   // Continue with In Progress state logic
