Creating and Using Student Object for Managing Student Details

CREATING AND USING STUDENT OBJECT

AIM: To write a program in Java to create and use objects of type Student to store the details like Register Number, Name and Marks in Three Subjects and to find the Total of Marks for 5 different students.

ALGORITHM:

Declare a Class named Student that define the student object with three data members namely RegNo, Name, and Marks. RegNo is of type int, Name is of type String and Marks is an array of int.
Define methods setRegNo() and getRegNo() for storing and retrieving data from RegNo
Define methods setName() and getName() for storing and retrieving data from Name
Define methods setMarks() and getMarks() for storing and retrieving data from Marks array
Declare 5 objects namely stud1, stud2, stud3, stud4 and stud5 of type Student in method main()
Call the set methods and get methods for each and every object for storing and retrieving data from all five objects

PROGRAM:

Student.java

import java.io.*;

public class Student {

public DataInputStream din;

public int RegNo, Total;

public String Name;

public int Marks[] = new int[3];

Student()

{

din = new DataInputStream(System.in);

Total = 0;

}

public void setRegNo() throws IOException

{

System.out.println("Enter the Register Number : ");

RegNo = Integer.parseInt(din.readLine());

}

public void getRegNo()

{

System.out.println("Register Number : " + RegNo);

}

public void setName() throws IOException

{

System.out.println("Enter the Name : ");

Name = din.readLine();

}

public void getName()

{

System.out.println("Name : " + Name);

}

public void setMarks() throws IOException

{

System.out.println("Enter the Three Marks (one by one) : ");

for(int i=0; i<3; i++)

{

Marks[i] = Integer.parseInt(din.readLine());

Total = Total + Marks[i];

}

public void getMarks()

{

System.out.println("Marks : " + Marks[0] + " " + Marks[1] + " "+ Marks[2]);

System.out.println("Total Marks : " + Total);

}

StudentObj.java

import java.io.IOException;

public class StudentObj

{

public static void main(String[] args) throws IOException

{

Student stud1, stud2, stud3, stud4, stud5;

stud1 = new Student();

System.out.print("\n");

System.out.println("Enter the Details of 1st Student : ");

stud1.setRegNo();

stud1.setName();

stud1.setMarks();

stud2 = new Student();

System.out.print("\n");

System.out.println("Enter the Details of 2nd Student : ");

stud2.setRegNo();

stud2.setName();

stud2.setMarks();

stud3 = new Student();

System.out.print("\n");

System.out.println("Enter the Details of 3rd Student : ");

stud3.setRegNo();

stud3.setName();

stud3.setMarks();

stud4 = new Student();

System.out.print("\n");

System.out.println("Enter the Details of 4th Student : ");

stud4.setRegNo();

stud4.setName();

stud4.setMarks();

stud5 = new Student();

System.out.print("\n");

System.out.println("Enter the Details of 5th Student : ");

stud5.setRegNo();

stud5.setName();

stud5.setMarks();

System.out.print("\n");

System.out.println("Details of Student-1");

stud1.getRegNo();

stud1.getName();

stud1.getMarks();

System.out.print("\n");

System.out.println("Details of Student-2");

stud2.getRegNo();

stud2.getName();

stud2.getMarks();

System.out.print("\n");

System.out.println("Details of Student-3");

stud3.getRegNo();

stud3.getName();

stud3.getMarks();

System.out.print("\n");

System.out.println("Details of Student-4");

stud4.getRegNo();

stud4.getName();

stud4.getMarks();

System.out.print("\n");

System.out.println("Details of Student-5");

stud5.getRegNo();

stud5.getName();

stud5.getMarks();

}

Sample Run:

Enter the Details of 1st Student :

Enter the Register Number :

13508309

Enter the Name :
