What Object-Oriented Programming (OOP) feature are you applying in your created design?

You create a class Freshman that needs to inherit from this interface. Which keyword in C# should you use to implement the interface in your class?

You are developing a mobile banking app. To prevent users from seeing the internal details of how transactions are processed, you design the system so they only interact with simple options like “Deposit,” “Withdraw,” and “Transfer.” Which Object-Oriented Programming (OOP) pillar are you applying to hide the complexity from the users?

During a programming activity, your instructor asked you to create a calculator class. You wrote two methods named Add: one accepts two integers, and the other accepts two doubles. When you ran the program, both methods worked correctly depending on the data type passed. This concept, where multiple methods share the same name but differ in parameter type or number, is called:

You are developing a C# application for a payroll system. In your design, you created a Person class that contains the constructor for initializing common details such as name and address. Later, you created a Employee class that inherits from Person. When writing the Employee constructor, you need to reuse and call the constructor of the Person class to avoid code duplication. Which keyword should you use to access the parent class constructor?

A software company is developing a payroll system where different types of employees (e.g., regular, contractual, and part-time) need to calculate their salary using the same method name calculateSalary(), but each employee type has its own way of computing it. What Object-Oriented Programming concept is being applied here?

Ana is designing a payroll system in Java. She declared some attributes in the Employee class as protected so that other classes can reuse them. Later, her Manager class inherits from Employee. During testing, she needs to verify where those protected attributes can be accessed. Based on this situation, in which part of the program can Ana successfully access the protected attributes of the Employee class?
