CSCI $2350$ Course Project

Phase $2$: Enhanced Functionality with Methods and Arrays $(100$ points$)$ Description:

Phase $2$ builds upon Phase $1$ by refactoring code to utilize methods for improved organization and introduces arrays for managing multiple student data efficiently.

Students will learn to encapsulate functionalities into methods $($addStudent$(),$ viewStudents$(),$viewAverageGrade$()),$ manage arrays for storing student data, and enhance code readability.

Demonstrates understanding of method declarations, method calls, array initialization, and usage in Java

Use the attached code of completed Phase $1$ of the project as a start point for your Phase $2.$ Instructions:

$1.$ Refactoring with Arrays:

o Introduce an array studentNames to store student names.

o Introduce a $2$D array studentGrades to store grades for multiple subjects $($assuming $3$ subjects$).$ o Initialize these arrays as class$-$level variables $($private static$).$

$2.$ Implement addStudent$()$ Method:

o Create a method addStudent$()$ to add a student to studentNames and studentGrades arrays.

o Prompt the user to input the student's name and grades for three subjects.

o Store the student's name in the studentNames array and their grades in the corresponding row of

the studentGrades array.

$3.$ Implement viewStudents$()$ Method:

o Create a method viewStudents$()$ to display details of all students stored in the studentNames and studentGrades arrays.

o Iterate through the arrays and display each student's name and their grades for the three subjects. $4.$ Implement viewAverageGrades$()$ Method:

o Create a method viewAverageGrades$()$ to calculate and display the average grade for each student stored in the studentGrades array.

o Compute the average grade for each student based on their grades for the three subjects and display the results.

$5.$ Modify main Method:

o Refactor the main method to utilize the newly created methods $($addStudent$(),$

viewStudents$(),$ viewAverageGrades$()).$

o Implement a menu$-$driven approach using a while loop to repeatedly prompt the user for

operations $($add student, view students, view average grades, exit$).$ Deliverables $($single java file$)$:

A revised version of StudentGradeManagementSystem.java using methods $($addStudent$(),$ viewStudents$(),$ viewAverageGrade$())$ and arrays $($students array$)$ for managing student data.

Include comments in your code to explain key sections, variables, methods, etc.
