Description
Instructions
The fourth programming project involves writing a program to manage a student database. The interface to the program
should be a GUI that looks similar to the following:
A combo box should allow the user to select one of the four database actions shown. The database should be implemented
as a HashMap, with the ID field as the key and a student record consisting of a name and major as the value. The operation
should be performed when the user clicks the Process Request button. If the user attempts to insert a key that is already in
the database an error message should be displayed using a JOptionPane message dialog box. If the user attempts to delete,
find or update a record that is not in the database, a message should also be displayed. After each successful operation is
completed a JOptionPane window should be displayed confirming the success. In the case of a successful Find request, a
window should pop up containing the student’s ID, name, major and current GPA. When the user selects the Update request,
the following JOptionPane windows should be displayed to gather information about a course that has just been
completed:

This program must consist of two classes. The first class should define the GUI and handle the database interactions. It
should be hand-coded and not generated by a GUI generator. The second class named Student, should define the student
record. It must have instance variables for the student name, major and two variables that are used to compute the GPA. A
variable that contains the total number of credits completed and a second variable that contains the total quality points,
which are the numeric value of the grade received in a course times the number of credit hours. It should not contain the
student ID. The class should have the following three methods:
1. A constructor that is used when new student records are created. It should accept the name and major as parameters
and initialize the fields that are used to compute the GPA to zero.
2. The second method courseCompleted should accept the course grade and credit hours and update the variables
used to compute the GPA. It will be called when an Update request is made.
3. The third method should override toString and return a labeled string containing the student name, major and GPA.
Be sure that all instance and class variables are declared as private. Also any exceptions thrown by nonnumeric inputs should
be properly handled. Finally when a student has not yet completed any course, the GPA should be displayed as 4.0.
