What is the best way to create a class in OOP for web development?

If you're like me, you won't remember what your code does next week. A confusing name will force me to study the code I wrote, or worse yet make me think that the method hasn't been written yet. Then I have 2 methods that do the same thing. Which makes everything that much more confusing because even if both methods are perfectly written and do the same exact thing, it makes no sense that both exist. Anyone with half a brain will see them and assume that their must be a reason that each one exists. Or worse yet, they will be named so bad, that they don't realize they do what they need, and they write their own version.

1?? Define the class with a clear, descriptive name. For example, User for a class handling user data. 2?? Define attributes that represent the class's properties. For a User, attributes might include username and email. 3?? Define methods that represent the behaviors of the class. For User, methods might include login() and logout(). 4?? Ensure encapsulation by making attributes private and accessing them via public methods (getters/setters). 5?? Use inheritance and composition to reuse code and build complex objects. 6?? In web development, classes often map to database tables. A User class might correspond to a users table.

Setting class attributes to protected or private forces class attributes to be only accessible from with in the object that was created from that class. This forces the programmer to access them from appropriate methods, usually with getters and setters. Or dealing damage to a character's health. You might want to track total damage done or handle other kinds of logic from applying the damage. A private or protected variable helps make sure that stuff that needs to happen happens. Or even something as simple as setting a new character name. You might need to check the maximum length, bad words within it, or that the name is available.

Account class example: public class Account { private double balance; // Encapsulation public Account(double initialBalance){ balance = initialBalance;} public void Deposit(double amount){ if (amount > 0) balance += amount;} public bool Withdraw(double amount){ if (amount <= balance){ balance -= amount; return true;} return false;} public double GetBalance() // Abstraction {return balance;}} the balance field, making it private and thus not directly accessible from outside the class. It provides public methods to deposit and withdraw funds, as well as a method to check the balance, abstracting away the details of balance manipulation.

//Single Responsibility Principle public class Notification{ public string Message { get; set; }} // Open/Closed Principle public interface INotificationSender{ void Send(Notification notification);} public class EmailSender : INotificationSender{ public void Send(Notification notification){}} // Liskov Substitution Principle public class SmsSender : INotificationSender{ public void Send(Notification notification){}} // Dependency Inversion Principle public class NotificationService{ private readonly INotificationSender _sender; public NotificationService(INotificationSender sender){_sender = sender;} public void Notify(Notification notification) {_sender.Send(notification);}} Service can use any ISender.
