Day 14: Classes

Tasks/Activities:

Activity 1: Class Definition

• Task 1: Define a class Person with properties name and age, and a method to return a greeting message. Create an instance of the class and log the greeting message.
• Task 2: Add a method to the Person class that updates the age property and logs the updated age.

Activity 2: Class Inheritance

• Task 3: Define a class Student that extends the Person class. Add a property studentId and a method to return the student ID. Create an instance of the Student class and log the student ID.
• Task 4: Override the greeting method in the Student class to include the student ID in the message. Log the overridden greeting message.

Activity 3: Static Methods and Properties

• Task 5: Add a static method to the Person class that returns a generic greeting message. Call this static method without creating an instance of the class and log the message.
• Task 6: Add a static property to the Student class to keep track of the number of students created. Increment this property in the constructor and log the total number of students.

Activity 4: Getters and Setters

• Task 7: Add a getter method to the Person class to return the full name (assume a firstName and lastName property). Create an instance and log the full name using the getter.
• Task 8: Add a setter method to the Person class to update the name properties (firstName and lastName). Update the name using the setter and log the updated full name.

Activity 5: Private Fields (Optional)

• Task 9: Define a class Account with private fields for balance and a method to deposit and withdraw money. Ensure that the balance can only be updated through these methods.
• Task 10: Create an instance of the Account class and test the deposit and withdraw methods, logging the balance after each operation.

Feature Request:

1. Basic Class Script: Write a script that defines a Person class with properties and methods, creates instances, and logs messages.
2. Class Inheritance Script: Create a script that defines a Student class extending Person, overrides methods, and logs the results.
3. Static Methods and Properties Script: Write a script that demonstrates static methods and properties in classes.
4. Getters and Setters Script: Create a script that uses getters and setters in a class.
5. Private Fields Script: Write a script that defines a class with private fields and methods to manipulate these fields (optional).

Achievement:

By the end of these activities, students will:

• Define and use classes with properties and methods.
• Implement inheritance to extend classes.
• Utilize static methods and properties.
• Apply getters and setters for encapsulation.
• Understand and use private fields in classes (optional).
