Q1: What is the purpose of the User class in a Social Media System?

Answer:

The User class is central to the social media system. It represents an individual user who interacts with the platform. This class contains attributes such as the username, email, profile picture, and biography. It also contains methods for actions like creating and updating a profile, following other users, posting content, liking or commenting on posts, and sending direct messages. The User class is responsible for managing user interactions and relationships within the platform.

Q2: What are the main differences between a Guest User and a Registered User?

Answer:

• Guest User: A guest is someone who does not have an account on the platform. They can browse public posts and profiles but cannot interact with the content (like or comment) or access private features such as messaging and posting.

• Registered User: A registered user has created an account and logged in. They can interact with the platform by liking posts, commenting, creating new posts, following other users, sending direct messages, and receiving notifications.

Q3: How does the Post class interact with the Comment class?

Answer:

The Post class and Comment class have a one-to-many relationship. A Post can have many Comments, while each Comment belongs to one Post. In the Post class, there is a list of comments (comments: List<Comment>) that holds all the comments related to the post. When a user comments on a post, a new Comment object is created and added to the post’s comment list.

Q4: How does the Notification system work in the Social Media platform?

Answer:

The Notification class is used to alert users of significant events. Notifications can be triggered by various actions like receiving a new message, being tagged in a post, a new follower, or a like/comment on a post. Notifications are created with a message and timestamp and are sent to the relevant user. They are stored in a list, and the user can view them within their profile. The Notification class keeps track of the status of each notification (read/unread).

Q5: What is the role of the Admin class in a Social Media system?

Answer:

The Admin class is responsible for managing the platform and ensuring the proper use of the system. Admins have special privileges that allow them to:

• Ban or delete users who violate the platform’s terms of service.
• Moderate content by reviewing posts, comments, and reports from users.
• Manage user access and remove inappropriate content from the platform.
  In contrast to regular users, admins have broader control over the platform’s operation.

Q6: How do users interact with posts on the Social Media platform?

Answer:

Users can interact with posts in multiple ways:

• Like a post: Users can click a ‘like’ button to express their appreciation for a post. The post then updates its list of likes.
• Comment on a post: Users can leave comments on posts, creating a thread of conversation under each post. Each comment belongs to one post.
• Share a post: A user can share a post with their followers or other users, helping to spread the content.
• Create posts: Users can create and share posts in text, image, or video form.

Q7: What is the function of the Authentication class in the system?

Answer:

The Authentication class handles user login and account verification. It allows users to authenticate themselves using their credentials (username/email and password). It manages the user session and ensures that only valid users can access the platform. The class verifies the user’s credentials during login and generates an authentication token for secure communication. If the credentials are incorrect, the user is denied access.

Q8: How does a user send a direct message to another user?

Answer:

To send a Direct Message, the user first creates a Message object containing the content of the message and specifies the sender and receiver. Once the message is created, it is sent through the Messaging System where the recipient receives it. The system can allow real-time messaging or store the messages in the database for later retrieval. The user can also read the messages from their inbox and respond to them.

Q9: What is the significance of the Profile Picture in the User class?

Answer:

The Profile Picture attribute in the User class is an important part of a user’s online identity on the platform. It serves as a visual representation of the user and is typically displayed next to their posts, comments, and messages. The profile picture can be updated by the user at any time, helping to personalize their profile and make interactions more identifiable and engaging for others.

Q10: How does the system handle content moderation?

Answer:

Content moderation is handled by the Admin class and involves monitoring user-generated content for compliance with the platform’s rules. Admins can manually review posts, comments, or messages flagged by users or the system for inappropriate content. The system may also implement automated filters for detecting offensive language or media. When necessary, an admin can remove or approve content, or even ban users who persist in violating the rules.

Q11: How does the social media platform handle notifications for user interactions?

Answer:

The system uses the Notification class to notify users about key events such as:

• Likes on their posts
• Comments on their posts or profile
• New followers
• Messages received Notifications can be sent in real time or as periodic updates. Each notification has a status (read or unread), and the user can view them within their notification center.
