Why do you prefer to create your own exception classes instead of using standard ones?

Creating custom exception classes allows:

• Improving code readability and maintainability. Specific exception names immediately indicate what exactly happened.

• Handling errors more precisely. You can catch specific exceptions without catching all.

• Adding additional information. Custom exceptions can store specific fields and methods to pass error context.

• Separating handling logic. Different types of exceptions may require different behaviors.

Example:

public class InvalidUserInputException extends Exception {
    public InvalidUserInputException(String message) {
        super(message);
    }
}

// Usage
if (input == null) {
    throw new InvalidUserInputException("Input cannot be null");
}

Thus, custom exceptions make the code more expressive and manageable.
