They can print these online booking receipts as a hard copy proof for traveling via local trains. The application consists of two accounts - Admin account and User account. Using the Admin account, the Admin can recharge the user account balance and view all the processed tickets of a user. When users log in to the application, they have to fill a ticket booking form to book tickets for the local trains traveling to their preferred destination. After users book ticket, they will receive the confirmation from the system. Draw a use case diagram and a class diagram for the above system.
