OOPs
In today's technology-driven world, computer programming skills are in high demand. The object-oriented programming (OOP) approach is very much useful while designing and maintaining software programs. Object-oriented programming (OOP) is a basic programming paradigm that almost every developer has used at some stage in their career.
Constructor
The easiest way to think of a constructor in object-oriented programming (OOP) languages is:
People in School
Objective:
At the end of the activity, the students should be able to:
- Create a
program that exhibits inheritance.
Procedure:
- Write a simple
information system that will store and display the complete information of a student, faculty, or employee. - Create four (4) no-modifier classes named Person, Student, Faculty, and Employee.
- Create a public class named CollegeList. This class shall contain the main method.
- Refer to the UML Class Diagram for the names of the variables and methods. The (-) symbol represents private variables, while (+) represents public method. This should be the sequence of the program upon execution:
-
- Prompt the user to select among Employee, Faculty, or Student, by pressing E, F, or S.
- Ask the user to type the name and contact
- For Employee, ask the user to type the employee's monthly salary and the department where he/she belongs to (Ex. Registrar). Then, display name, contact number, salary, and
-
For Faculty, ask the user to press Y if the faculty member is regular/tenured or N if not. Then, display name, contact number, salary, department, and status.
For Student, ask the user to type the student's enrolled program (Ex. BSIT, BSTM) and his/her year level (integers 1 to 4). Then, display name, contact number, program, and year level.

Invoice - ID:intdef swap_text(text): Backstory: Luffy wants to organize a surprise party for his friend Zoro and he wants to send a message to his friends, but he wants to encrypt the message so that Zoro cannot easily read it. The message is encrypted by exchanging pairs of characters. Description: This function gets a text (string) and creates a new text by swapping each pair of characters, and returns a string with the modified text. For example, suppose the text has 6 characters, then it swaps the first with the second, the third with the fourth and the fifth with the sixth character. Parameters: text is a string (its length could be 0)Return value: A string that is generated by swapping pairs of characters. Note that if the Examples: swap_text ("hello") swap_text ("Party for Zoro!") swap_text ("") def which_day(numbers): → 'ehllo'→ 'aPtr yof roZor!' → '' length of the text is odd, the last character remains in the same position.
