Assessment Task: Paired Programming
Part A
In this assignment, you are required to write a Java Application that uses an interactive Graphical User Interface (GUI) based on the JFrame class using SWING GUI components. You will also be designing and implementing the software solution using appropriate data structures and application of classes, inheritance, and exception handling. The case study for developing a solution is given below. You will be connecting to a database programmatically and executing necessary SQL queries within your java program.
Year 11 and 12 students study five subjects. There are many assessments for these subjects in different formats and the grade of these assessments are summative contributing to a student’s results. Your task is to extend the Java Application developed for Assignment One such that an administrator can enter details of students with their assessment details for all enrolled subjects and set grade. Students or parents can view the details by entering a student name and year level.
The database will have the following tables:
1. Student table having studentId (primary key): a 4 digit number, studentName: string (30 characters), and yearLevel: 2 digit number
2. Subject table: In addition to the existing attributes this table will have subjectId (primary key): 2 digit number, and studentId as the foreign key
3. Assessment table: extend the Assessment attributes from Assignment One to include an Assessment Id: a single digit number starting at 1. The primary key will be a composite key consisting of subjectId and AssessmentId
4. Grades table: store the values of Grade shown in Table 3. Use the Degree of achievement as the primary key
5. StudentGrade to store the set grade for an Assessment item of a student (use composite key of StudentId, subjectId, AssessmentId, and gradeId.
Note: The table listings only show the values to be stored as per the user requirements. The primary keys are generated during the programmatic creation of the tables and used for other database operations. These keys need not be displayed to the user. The primary keys can be auto-incremented integer values. One Student should enrol in five Subjects and each Subject is enrolled by many Students. (many – to – many). You may add additional tables as required for the correct functioning of the database. Create an ERD to understand the relationship between tables.
In addition to the GUI components you have in Assignment One, include the following components.
Save Button in the bottom panel, to save the user data to the database.
The functions of the eight buttons are described below.
Initially the ‘Create Student’, ‘Load Assessment’, ‘Save’, and ‘Set Grade’ buttons remain disabled. This is shown in Figure 1.
Figure 1. Screen shot of Initial Display
An administrator enters the name (admin) and password (admin), and clicks the Login button. This enables the ‘Create Student’ button for the first run.
In subsequent runs, if the ‘Save’ button has been clicked and data saved to the database, then the admin login should load the data structures from the database. So the ‘Load Assessment’ button should remain disabled. This should also enable the buttons ‘Create Student’, ‘Set Grade’ and ‘Save’.
Administrator Functions
1. Create Student
The administrator enters Student Name and Year Level using the fields on the GUI and clicks the ‘Create Student’ button which creates a student object. While creating the Student object, three core subjects of English, Mathematics B, and Biology, and the chosen elective subjects of, Business and Communication Technologies, and Religion and

Ethics are added to the student object. This is done to simplify the process of going through adding each subject. The administrator can enter more than one student. Table 1 Test Data for Students

2. Load Assessments
The ‘Load Assessments’ Button will be enabled after the ‘Create Student’ button is clicked creating a student object. The ‘Load Assessments’ Button can be used to read the data file which contains the Assessment List for all the subjects. After loading the file, the loaded Assessment details are added to the corresponding subjects. The first field in each assessment item in the file is the subject name and this should be used to correctly add the assessments to the corresponding subjects. The ‘Load Assessments’ Button should also populate the Combo Boxes for Subjects, Assessments, and Degree of achievements with corresponding set of values. After loading the assessments enable the ‘Save’ and ‘Set Grade’ buttons.

Due date Wed 9 - Wed 16 March 2017
Note: Use the given data file named COIT20256Ass2Data.csv available in the Unit website and it contains the set of data required.
3. Set Grade
Clicking on the “Set Grade” button allows the administrator to set the Degree of achievement for a chosen Assessment Item, for a chosen student, and subject. The grading contains levels of achievements, knowledge, and skill. These values are given in the following Table 2. Once the administrator selects the Degree of achievement using the Combo Box, corresponding levels of knowledge and skill should be added.
Table 3. Grading Details
Degree of achievement: Degree of knowledge and understanding: Degree of skill and use of skill:
Very high thorough understanding uses a high level of skill in both familiar and new situations
clear understanding uses a high level of skill in familiar situations, and is beginning to use skills in new situations
uses skills in situations familiar to them
Developing understands aspects of
uses varying levels of skill in situations familiar to them
Emerging basic understanding beginning to use skills in familiar situations
4. Save
This button should allow the entered Student data, subject, assessment details and grades to be saved to the database.
General Functions
5. Display Assessments
This button has the same functionality as in Assignment One. This should display all the assessment details of a chosen subject in the Text Area as shown in Figure 4. The last value ‘false’ indicates the assessment item is not yet graded. You can use ‘not graded’ instead of false which may be more meaningful.

6. Display Grade
This can be used to display the grades of various assessments set already in the TextArea as shown in Figure 5. A parent or student has to enter the student name and year level before clicking the Display Grade button.
Figure 5 Display Grade
An admin can display the grades of all students enrolled for a chosen subject, or a chosen Assessment.
7. Clear Display
User clicks this button to clear the TextArea, TextFields, and set the ComboBoxes to the default value.
8. Exit
This should allow the user to quit the application.
Data Structures.
DatabaseUtility class: Create this class to implement all the tasks related to creation of database and table, extracting records from the database. Use Prepared statements to get the user input from GUI interface and use them for populating database.
Also use prepared statements to execute query to extract data and store the records in a linked list.
You can use the classes used in Assignment One. You don’t have to create a class for the admin user. Use Linked list instead of ArrayList to store data belonging to multiple objects.
Paired Programming
Complete the assignment working in pairs. You can choose your partner yourself. You should ensure that you inform your tutor about the partner and if you have any problem with choosing a partner, please inform your tutor. Distance students also can work in pairs. If there are any problems please contact the Unit Coordinator.
Individual Report
Your report should be written individually and submitted by each one of you. In your report clearly show your partner for the application development.
1. Write how the Study Progress Monitor can be extended to allow teachers teaching each subject can enter their results. You need to write about the additional data structures required for this.
2. Provide your view of using any data structures such as stacks, queues or sets to improve coding efficiency.
3. Clearly indicate the tasks / parts of application development carried out by you.
4. Write you experience of using paired programming clearly indicating the advantages and disadvantages if any.
5. Include a test plan, and user instructions.
Software Tools for Building the Application
You can build your application using the TextPad Editor or NetBeans. It is highly recommended that you create the GUI components using code rather than 'designer' and 'click and drag' of the NetBeans. This creates code which is not maintainable. Remember this is a good prototyping tool, but not recommended for coding.
Note: Commence with creating each class saving to the database tables and progress step by step.
Assignment Submission
You should submit the following source code files using the Moodle online submission
system. (Note: the file names/class names could be changed to meaningful names)
• – Source code for the Student class
• – Source code for the Subject class
• – Source code for Assessment class
• – Source code for programmatic operation of the database
• – Source code for the GUI components, other required methods as outlined above and the main method.
The application program should create the database and necessary tables. So there is no need to submit any database files. Only one submission per pair is required. Individual Submission
• Report.docx – File containing topics as per the individual report, test plan, and test details
