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

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

StudentDB class

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

This class should have two methods.

addwrites 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.
