Javier Gonzalez-Sanchez | CSE360 | Fall 2020 | 3 What to submit 1. Team Project Source code in Java. All classes in the default package, i.e., no package instruction used. Use only Java AWT, Java Swing Only one external library allowed: JFreeChart
Javier Gonzalez-Sanchez | CSE360 | Fall 2020 | 4 What to submit 2. Project Report • Class diagram. It is not an adornment. It should match 100% with the source code: association, aggregation, composition, realization, generalization. • Screenshot(s) of your project running.
Javier Gonzalez-Sanchez | CSE360 | Fall 2020 | 5 Alert Talk with your team about expectations before start working. Review carefully if your team expectations match what you are able to / want to do. Including: getting an A+ vs I am ok with a C-, morning vs night people etc., etc., etc.
Javier Gonzalez-Sanchez | CSE360 | Fall 2020 | 6 User Interface § A GUI with a menu bar (Use a JMenu) § Two items: File and About § About is Easy, will open a dialog box with your team information. § File menu is the important one Jmenu Tutorial https://docs.oracle.com/javase/tutorial/uiswing/components/menu.html
Javier Gonzalez-Sanchez | CSE360 | Fall 2020 | 8 Load a Roster • Ask the user for a File path (Use a JFileChooser) • The file will be a CSV (Comma Separated Values) file. • Read the file and load the data into a data structure (your choice) JFileChooser Tutorial: https://docs.oracle.com/javase/tutorial/uiswing/components/filechooser.html How to Read CSV File in Java https://www.tutorialspoint.com/how-to-read-the-data-from-a-csv-file-in-java
Javier Gonzalez-Sanchez | CSE360 | Fall 2020 | 9 Roster File / / / • The file does not have headers (orange line). Added only as a reference. • 6 fields per row
Javier Gonzalez-Sanchez | CSE360 | Fall 2020 | 10 Load a Roster • Once the data is loaded, visualize it on the screen using a Jtable • Add your JTable in a JScrollPane, you will need scrollbars, both horizontal and vertical Jtable Tutorial https://www.javatpoint.com/java-jtable Dinamically Updating a JTable https://stackoverflow.com/questions/24918884/dynamically-updating-jtable
Javier Gonzalez-Sanchez | CSE360 | Fall 2020 | 11 Add Attendance • Ask the user for a File path (Use a JFileChooser) • The file is another CSV (Comma Separated Values) file. • Ask for a date Use a Date Picker. Get One or create one • Read the file and load the data into a data structure (one more time, your choice) • Remember the selected date
Javier Gonzalez-Sanchez | CSE360 | Fall 2020 | 12 Attendance File • Same asurite can appear in more than one row. For instance, a user is connected 20 minutes, go and then connect another 20 minutes. It will appear as jdoe 20 jdoe 20 Merge them in one. And add the minutes. For instance: jdoe 40 75 time ASURITE javiergs • The file does not have headers (orange line). Added only as a reference. • 2 fields per row: • ASURITE (your username in the email) • An integer number that represent how many minutes you where connected in a meeting
Javier Gonzalez-Sanchez | CSE360 | Fall 2020 | 13 Roster + Attendance • Using the asurite field as a reference, mix the roster data and the attendance data • Visualize the attendance data adding a column to the JTable. The header for the column is the date that the user provided • Any attendee that is not in the roster is ignored. But report it to the user. Use an option of JDialog
Javier Gonzalez-Sanchez | CSE360 | Fall 2020 | 14 Roster + Attendance * • N Attendance Files can be loaded for the same Roster File. Each one add a new column
Javier Gonzalez-Sanchez | CSE360 | Fall 2020 | 15 Save • Save all data (exactly what we have in the JTable) in a CSV file • For this file, save the headers also.
Javier Gonzalez-Sanchez | CSE360 | Fall 2020 | 16 Plot Data • Create a Chart using the attendance data per student. Specifically, a Scatter Plot were • Y-Axis is how many students (from 0 to total row in the table) • X-axis is % of attendance (0%, 10% .. 90%, 100%). 100% is 75 minutes or more. • And each attendance column represent a population.
Javier Gonzalez-Sanchez | CSE360 | Fall 2020 | 17 Plot Data • Either add a new JPanel, replace the JTable, Use a tab (JTabbedPane) or a dialog box • Use the JFreeChart library. Mandatory. Tutorial: https://www.javatpoint.com/jfreechart-scatter-chart
