Lesson: 75 | Vehicle Inventory Management

User Story

As a dealership manager, I want to leverage Apex classes to enhance the vehicle inventory management system in Salesforce. I need to customize the display of vehicle details and calculate the total price based on specific features for cars, motorcycles, and trucks.

Acceptance Criteria:

As a dealership manager, I want to create a custom Apex class called "Car" that extends the abstract class "Vehicle" and includes additional attributes such as "bodyType".
The "Car" class should override the "displayDetails()" method to display the car's make, model, year, and body type.
The "Car" class should also override the "calculateTotalPrice()" method to include custom logic for calculating the total price of a car, considering additional charges for specific features.
Similarly, I want to create a custom Apex class called "Motorcycle" that extends the abstract class "Vehicle" and includes the "style" attribute.
The "Motorcycle" class should override the "displayDetails()" method to display the motorcycle's make, model, year, and style.
The "Motorcycle" class should also override the "calculateTotalPrice()" method to include custom logic for calculating the total price of a motorcycle, considering customization charges.
Additionally, I want to create a custom Apex class called "Truck" that extends the abstract class "Vehicle" and includes the "loadCapacity" attribute.
The "Truck" class should override the "displayDetails()" method to display the truck's make, model, year, and load capacity in tons.
The "Truck" class should also override the "calculateTotalPrice()" method to include custom logic for calculating the total price of a truck, considering additional charges for towing capabilities.

Code

Abstract Class

public abstract class Vehicle {
    public String make;
    public String model;
    public Integer year;
    public Decimal price;

    public abstract void displayDetails();
    public abstract void calculateTotalPrice();
}

Car Class:

public class Car extends Vehicle {
    public String bodyType;

    public override void displayDetails() {
        System.debug('Car Details: ' + make + ' ' + model + ', Year: ' + year + ', Body Type: ' + bodyType);
    }

    public override void calculateTotalPrice() {
        // Custom logic for calculating total price of a car
        // Example: price + additional charges for features
    }
}

Motorcycle Class:

public class Motorcycle extends Vehicle {
    public String style;

    public override void displayDetails() {
        System.debug('Motorcycle Details: ' + make + ' ' + model + ', Year: ' + year + ', Style: ' + style);
    }

    public override void calculateTotalPrice() {
        // Custom logic for calculating total price of a motorcycle
        // Example: price + customization charges
    }
}

Truck Class:

public class Truck extends Vehicle {
    public Integer loadCapacity;

    public override void displayDetails() {
        System.debug('Truck Details: ' + make + ' ' + model + ', Year: ' + year + ', Load Capacity: ' + loadCapacity + ' tons');
    }

    public override void calculateTotalPrice() {
        // Custom logic for calculating total price of a truck
        // Example: price + additional charges for towing capabilities
    }
}
