Using noun extraction, find the classes, their attributes and the methods necessary for the following project. Create UML Class Diagrams to summarize your findings. The Class Diagram must show the attributes with data types, functions with return types and all parameters with data types. Please in answer in the simplest java code possible with explanation comments using //

The RTA asked you to create an application which acts as a vehicle management system for different modes of transportation in Dubai. The system has a list of transportation devices which it should be able to display and search in by registration ID. The different modes of transportation include buses, metros and cars. All transportation devices have their capacity and the number of people in them tracked, as well as their allowed speed limit and current speed. The system should have a function that parses the list of transportations and fines them if they are going over the speed limit. Naturally, the system should allow adding and removing different vehicles.

All vehicles can be started and stopped and people can take the modes of transportation if there is free space in them. The system should give an error if the user tries to start a vehicle already running, or stop a vehicle that's not running. Buses and Metros have a price which the user is asked to pay before tanking them. Cars have the owner's name registered and will ask the user to enter their name before they are allowed to take the car. Buses and Cars have their model and make stored.

2) Implement the above project with at least one abstract class and inheritance. Create a tester class which demonstrates the use of the vehicle system.

3) Implement another version of the project that uses interfaces instead of abstract classes.
