Final answer:
Certainly! Here's a Python example of the `Course` class implementing the specified requirements:
```python
class Course:
def __init__(self, course_id, course_title, semester):
self.course_id = course_id
self.course_title = course_title
self.semester = semester
def __str__(self):
return f"Course ID: {self.course_id}, Course Title: {self.course_title}, Semester: {self.semester}"
def __eq__(self, other):
if isinstance(other, Course):
return self.course_id == other.course_id
return False
```
Step-by-step explanation:
This Python class, `Course`, has attributes `course_id`, `course_title`, and `semester`. It has an overloaded constructor that takes in these attributes to initialize the `Course` object. The `__str__` method provides a string representation of the `Course` object, displaying its details. The `__eq__` method overrides the equality comparison, making two courses equal if they have the same `course_id`.
You can create instances of the `Course` class and compare them based on their `course_id`. For example:
```python
# Creating instances of Course
course1 = Course(1, "Mathematics", "Spring")
course2 = Course(2, "History", "Fall")
course3 = Course(1, "Biology", "Summer")
# Printing course details
print(course1) # Output: Course ID: 1, Course Title: Mathematics, Semester: Spring
print(course2) # Output: Course ID: 2, Course Title: History, Semester: Fall
# Checking equality
print(course1 == course2) # Output: False
print(course1 == course3) # Output: True
```
This example demonstrates the creation of `Course` instances, printing their details using the `__str__` method, and checking their equality using the overridden `__eq__` method based on the `course_id`.
