Class & Object - Student Marks Program - ICSE 2010 Computer Science

Define a class Student as given below:

Data members/instance variables:
name: to store the student’s name.
age: to store the age.
m1, m2, m3: to store the marks in three subjects.
maximum: to store the highest marks among three subjects.
average: to store the average marks.

Member functions:
(i) A parameterized constructor to initialize the data members.
(ii) To accept the details of a student.
(iii) To compute the average and the maximum out of three marks.
(iv) To display all the details of the student.

Write a main() method to create an object of the class and call the above methods accordingly to enable the task.

Java 

import java.util.Scanner;
class Student{
    String name;
    int age;
    int m1;
    int m2;
    int m3;
    int maximum;
    double average;
    public Student(String n, int a, int m1, int m2, int m3){
        name = n;
        age = a;
        this.m1 = m1;
        this.m2 = m2;
        this.m3 = m3;
        maximum = 0;
        average = 0.0;
    }
    public void accept(){
        Scanner in = new Scanner(System.in);
        System.out.print("Name: ");
        name = in.nextLine();
        System.out.print("Age: ");
        age = Integer.parseInt(in.nextLine());
        System.out.print("Marks 1: ");
        m1 = Integer.parseInt(in.nextLine());
        System.out.print("Marks 2: ");
        m2 = Integer.parseInt(in.nextLine());
        System.out.print("Marks 3: ");
        m3 = Integer.parseInt(in.nextLine());
    }
    public void compute(){
        maximum = Math.max(m1, m2);
        maximum = Math.max(maximum, m3);
        average = (m1 + m2 + m3) / 3.0;
    }
    public void display(){
        System.out.println("Name: " + name);
        System.out.println("Age: " + age);
        System.out.println("Marks 1: " + m1);
        System.out.println("Marks 2: " + m2);
        System.out.println("Marks 3: " + m3);
        System.out.println("Maximum: " + maximum);
        System.out.println("Average: " + average);
    }
    public static void main(String args[]){
        Student obj = new Student("", 0, 0, 0, 0);
        obj.accept();
        obj.compute();
        obj.display();
    }
}

Output
