Define a class Student with the following specifications:

• Data Members/Instance Variables:

  • name, age, m1, m2, m3, maximum, average

• Member Methods:

  1. A parameterized constructor to initialize the data members.
  2. A method to accept the details of a student.
  3. A method to compute the average and the maximum out of the three marks.
  4. A method to display the name, age, marks in three subjects, maximum, and average.

Write a main method to create an object of the Student class and call the above member methods.

Given Input:

Expected Output:

Name: John Doe
Age: 20
Marks in Subject 1: 85
Marks in Subject 2: 90
Marks in Subject 3: 88
Maximum Marks: 90
Average Marks: 87.66666666666667

Program:

import java.io.*;

class Student {
    // Data members/instance variables
    String name;
    int age, m1, m2, m3, maximum;
    double average;

    // Parameterized constructor to initialize the data members
    public Student(String name, int age, int m1, int m2, int m3) {
        this.name = name;
        this.age = age;
        this.m1 = m1;
        this.m2 = m2;
        this.m3 = m3;
        compute(); // Calculate average and maximum during initialization
    }

    // Method to accept the details of a student
    void accept() throws IOException {
        BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
        System.out.println("Enter name:");
        name = br.readLine();
        System.out.println("Enter age:");
        age = Integer.parseInt(br.readLine());
        System.out.println("Enter marks in three subjects:");
        m1 = Integer.parseInt(br.readLine());
        m2 = Integer.parseInt(br.readLine());
        m3 = Integer.parseInt(br.readLine());
        compute(); // Calculate average and maximum after updating details
    }

    // Method to compute the average and the maximum out of three marks
    void compute() {
        average = (m1 + m2 + m3) / 3.0;
        if (m1 >= m2 && m1 >= m3) {
            maximum = m1;
        } else if (m2 >= m1 && m2 >= m3) {
            maximum = m2;
        } else {
            maximum = m3;
        }
    }

    // Method to display the name, age, marks in three subjects, maximum, and average
    void display() {
        System.out.println("Name: " + name);
        System.out.println("Age: " + age);
        System.out.println("Marks in Subject 1: " + m1);
        System.out.println("Marks in Subject 2: " + m2);
        System.out.println("Marks in Subject 3: " + m3);
        System.out.println("Maximum Marks: " + maximum);
        System.out.println("Average Marks: " + average);
    }

    // Main method to create an object of the class and call the member methods
    public static void main(String[] args) throws IOException {
        // Create an object with initial values
        Student student = new Student("John Doe", 20, 85, 90, 88);

        // Display initial details
        student.display();

        // Update details with user input
        student.accept();

        // Display updated details
        student.display();
    }
}
