Question

Define a class Student with the following specifications: 

Class name: Student
Instance variables/Data Members:
String name: to store the name of the student
int eng: to store marks in English
int hn: to store marks in Hindi
int mts: to store marks in Maths
double total: to store total marks
double avg: to store average marks
Member methods:
void accept(): to input marks in English, Hindi and Maths
void compute(): to calculate total marks and average of 3 subjects
void display(): to show all the details viz. name, marks, total and average

Write a program to create an object and invoke the above methods.

Answer 1

import java.util.*;
class Student{
String name;
int eng, hn, mts;
double total, avg;

void accept()
{Scanner sn = new Scanner(System.in);
System.out.print("Name: ");
name = sn.nextLine();
System.out.print("Eng Mark: ");
eng = sn.nextInt();
System.out.print("Hindi Mark: ");
hn = sn.nextInt();
System.out.print("Maths Mark: ");
mts = sn.nextInt();
}

void compute()
{total = eng + hn + mts;
avg = total / 3;
}

void display()
{System.out.println("\n\nOUTPUT");
System.out.println("Name: " + name);
System.out.println("Eng: " + eng);
System.out.println("Hin: " + hn);
System.out.println("Math: " + mts);
System.out.println("Total: " + total);
System.out.println("Avg: " + (float) avg);
}

public static void main(String args[])
{Student ob = new Student();
ob.accept();
ob.compute();
ob.display();
}}
