Question

Define a class called Student to check whether a student is eligible for taking admission in class XI with the following specifications:

Instance variables/Data members:
String name: to store name
int mm: to store marks secured in Maths
int scm: to store marks secured in Science
int comp: to store marks secured in Computer
Member Methods:
Student(): parameterised constructor to initialize the data members by accepting the details of a student
check(): to check the eligibility for course with the following conditions:

Marks	Eligibility
90% or more in all the subjects	Science with Computer
Average marks 90% or more	Bio-Science
Average marks 80% or more and less than 90%	Science with Hindi

display(): to display the eligibility by using check() function in nested form.

Write the main method to create an object of the class and call all the member methods.

Answer 1

import java.io.*;
class Student{
String name;
String status = "";
int mm, scm, comp;

Student (String a, int b, int c, int d)
{ name = a;
mm = b;
scm = c;
comp = d;
}

void check()
{double tot, pcent;
tot = mm + scm + comp;
pcent = (tot / 300) * 100;
if (mm >= 90 && scm >= 90 && comp >= 90) status = "Science with Computer";
else if (pcent >= 90) status = "Bio Science";
else if (pcent >= 80 && pcent <= 90) status = "Science with Hindi";
}

void display()
{System.out.println("Eligible for the course: " + status);
}

public static void main(String args[]) throws IOException
{ String n;
int m1, m2, m3;
BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
System.out.println("Enter the name");
n = br.readLine();
System.out.println("Enter maths mark");
m1 = Integer.parselnt(br.readLine());
System.out.println("Enter science mark");
m2 = Integer.parselnt(br.readLine());
System.out.println("Enter Comp mark"); 
m3 = Integer.parselnt(br.readLine());
Student obj = new Student(n, m1, m2, m3); // calling parameterized constructor
obj.check(); // calling the other two methods
obj.display();
