CIS 355A Week 6 Lab Student Management System

OBJECTIVES

• Programmatic access to a MySQL database to add and display records

PROBLEM: Student Management System
A teacher needs the ability to store and retrieve student data. This includes

• student name;
• three test scores;
• average; and
• letter grade.

FUNCTIONAL REQUIREMENTS
You can code the GUI by hand or use NetBeans GUI builder interface.
Create a GUI which allows for input and display of student data.
It should include buttons to save a record, display all records.

Create a database and table to store student name and three test scores. (Note that average and grade are calculated by app.)

Student class
Create a Student class to manage the student data. It should have private instance variables of

• student name; and
• three test scores.

The class must have the following methods.

• A default and parameterized constructor
• Sets/gets for all instance variables
• A get method to calculate and return the average
• A get method to calculate and return the letter grade
• toString to display the name of the student

StudentDB class
Create a StudentDB class that is used to create a connection and interface with the database.

This class should have two methods.

• getAll—reads data from database, returns data in an arraylist of student objects
• add—writes a record to the database

GUI class

Insert button will take the info from the GUI (student name and three test scores) and insert a record into the table. Input should be cleared from the textboxes.

Display button will read the data from the database and creates a report in Console window, sample format below.

Name	Test1	Test2	Test3	Avg	Grade
Bruce Wayne	90	95	98	94.3	A
Clark Kent	65	70	90	75.0	C
