Question

7 essay 20 points create a student class with properties like name, age, and grade and a method to display student details.

Explanation:

Step1: Define the Student class

We'll create a class named Student with attributes name, age, and grade. In Python, we can define the class and its init method to initialize the attributes.

class Student:
    def __init__(self, name, age, grade):
        self.name = name
        self.age = age
        self.grade = grade

Step2: Add a method to display details

We'll add a method called display_details that prints out the student's information.

    def display_details(self):
        print(f"Name: {self.name}, Age: {self.age}, Grade: {self.grade}")

Step3: Test the class (optional but good practice)

We can create an instance of the Student class and call the display_details method to see if it works.

# Create a student instance
student1 = Student("John Doe", 15, "9th")
# Call the display method
student1.display_details()

When we run this code, it will create a student object and display their details. The full code for the Student class would be:

class Student:
    def __init__(self, name, age, grade):
        self.name = name
        self.age = age
        self.grade = grade

    def display_details(self):
        print(f"Name: {self.name}, Age: {self.age}, Grade: {self.grade}")

If we were to use a different programming language like Java, the code would be:

public class Student {
    private String name;
    private int age;
    private String grade;

    public Student(String name, int age, String grade) {
        this.name = name;
        this.age = age;
        this.grade = grade;
    }

    public void displayDetails() {
        System.out.println("Name: " + name + ", Age: " + age + ", Grade: " + grade);
    }

    // Getters and setters (optional but often useful)
    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public int getAge() {
        return age;
    }

    public void setAge(int age) {
        this.age = age;
    }

    public String getGrade() {
        return grade;
    }

    public void setGrade(String grade) {
        this.grade = grade;
    }
}

// To test the class:
class Main {
    public static void main(String[] args) {
        Student student1 = new Student("John Doe", 15, "9th");
        student1.displayDetails();
    }
}

This Java code defines the Student class with the required properties and the method to display details, and also includes a main method to test the class.

Answer:

The following is a Python implementation of the Student class:

class Student:
    def __init__(self, name, age, grade):
        self.name = name
        self.age = age
        self.grade = grade

    def display_details(self):
        print(f"Name: {self.name}, Age: {self.age}, Grade: {self.grade}")

# Example usage:
student = Student("Alice", 16, "10th")
student.display_details()

Or in Java:

public class Student {
    private String name;
    private int age;
    private String grade;

    public Student(String name, int age, String grade) {
        this.name = name;
        this.age = age;
        this.grade = grade;
    }

    public void displayDetails() {
        System.out.println("Name: " + name + ", Age: " + age + ", Grade: " + grade);
    }

    public static void main(String[] args) {
        Student student = new Student("Bob", 14, "8th");
        student.displayDetails();
    }
}
