Generate a detailed class diagram starting from the following problem description: define the required classes, their

attributes $($type and name$),$ the signature of the methods and the relationships between different classes.

Problem description:

Share$-$a$-$Bike is replacing their rental shops with digital rental stations that keep track of bike bookings and

movement. Each rental station provides the following core functionality: It consists of an overview of return stations

$($i$.$e$.,$ places in Leuven where you can return a bike$),$ and also maintains a user database. Users have a name, and an

age. Bike bookings have a start time, include the name of the station at which the bike was booked, and the one at

which the user intends to return it$.$ Depending on the chosen rental duration, the price is calculated. Prices are

adapted based on user $($age$)$ and rental duration $($amount of time the user assumes they will need the bike$).$ Every

time a user books a bike, the price for the given rental is calculated. The system maintains a record of the users who

booked a given bike; for every user, the system maintains an overview of the total amount of money spent on bike

rentals. Further, the digital rental station maintains the total volume $($money$,$ you can assume Euros$)$ of bike rentals

sold so that Share$-$a$-$Bike gets an overview of its most profitable rental stations.

For administrative purposes, it must be possible to add new users and return stations to an existing rental station,

and to retrieve users based on their username. To set up a new rental station, it needs to be possible to import

information on all existing other stations from a database. This method returns the number of imported stations.

Another requirement is the possibility of retrieving the rental with the longest duration that was booked by a user.

Additionally, Share$-$a$-$Bike would like to be able to retrieve a list of rental stations where customers spend significant

amounts of money on their bike rentals so that they can target future expansion
