Question

Using the various Object Oriented Programming concepts and skills learnt in this course, design and develop a Java Application to compute an individual student’s GPA and store the records in a database.

The application should have two components i.e. The student and the course components.

The following should be the minimal operations on the course component:

– Set course information

– Print course information

– Show credit hours

– Show course number

The following should be the minimal operations on the student component

– Set student information

– Print student information

– Calculate number of credit hours taken

– Calculate GPA

– Calculate billing amount (NB: @credit unit is $555)

– Sort the courses according to the course number

Answer 1

//THE BELOW ALGORITHM IS WRITTEN IN JAVA. IT CAN BE IMPLEMENTED IN ANY OBJECT ORIENTED PROGRAMMING LANGUAGE.

import java.io.*;

import java.util;

class student

{

public static void main(String[] args)

{

//setting the course information

public void course()

{

//get all the necesary information from the usre

//store all the information in proper datatypes

}

public void printcourse()

{

//print all the course information

}

public int creditHours()

{

//return the credit hours

}

public int courseNumber()

{

//return the course number

}

//CALLING THE PREVIOUSLY DEFINED METHODS

int ch=creditHours();

int cn=courseNumber();

//FOR THE STUDENT COMPONENT

public void stuInfo()

{

//store the student information in proper datatype

}

public void printStuInfo()

{

//print the student info

}

public int credit()

{

//calculating the number of credit hours

}

public void GPA()

{

//calculate gpa

//print gpa

}

public float bill()

{

//calculate and return billing amount

}

public void sortCourse()

{

//sort the course according to the course number

}

//CALLING THE NON VOID METHODS

float b=bill();

//b can be used as the billing amount

}//closing main

}//closing class
