Electronic Device Inventory System

Description

You will enhance a basic inventory system to include methods for comparing devices and managing device counts. You will also introduce an Inventory class to keep track of the devices.

Instructions

1. Define the Base Class

Create a class named ElectronicDevice with the following properties:

• brand (String)
• model (String)

Implement a constructor to initialize these properties. Include a method named displayDetails() that prints out the details of the device. Add a method named compareModel(ElectronicDevice other) that returns a boolean indicating whether the model of the current device is the same as the model of the other device.

2. Define Derived Classes

Smartphone Class:

Create a class named Smartphone that extends ElectronicDevice. Add an additional property: batteryLife (int, in hours). Implement a constructor to initialize the brand, model, and batteryLife. Override the displayDetails() method to include the batteryLife information.

Laptop Class:

Create a class named Laptop that extends ElectronicDevice. Add an additional property: ramSize (int, in GB). Implement a constructor to initialize the brand, model, and ramSize. Override the displayDetails() method to include the ramSize information.

3. Define the Inventory Class

Create a class named Inventory that manages a list of ElectronicDevice objects. Include methods to:

• Add a device to the inventory.
• Remove a device from the inventory by model.
• Count the total number of devices in the inventory.
• Display details of all devices in the inventory.

4. Create Objects and Manage Inventory

Create instances of Smartphone and Laptop. Use the Inventory class to add these devices to the inventory. Demonstrate removing a device, counting the total number of devices, and displaying details of all devices in the inventory. Use the compareModel() method to compare two devices and print out the result.

Submission

• Submit the Dart code for the base class, derived classes, and the Inventory class.
• Demonstrate the functionality by creating instances, managing the inventory, and using the comparison method.

Evaluation Criteria

• Correct implementation of inheritance and method overriding.
• Proper functionality of the Inventory class methods.
• Accurate use of the compareModel() method.
• Effective demonstration of managing the inventory and displaying device details.
