CIS355A Week 6 Lab—Database Connectivity

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 the following.

· Student name

· Three test scores

· Average

· 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 and 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 and 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 text boxes.

Display button will read the data from the database and create a report in the 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
