  3. PRG 421 guide PRG 421 Week 1 Supporting Activity Events and GUIs PRG 421 Week 1 Supporting Activity Java Containers • What is an event? How are events and graphical user interfaces (GUIs) related? Provide an example of an event and relate it to a GUI. • How are containers used in the Java® language? Write a small program in which you add components to a container. Then post the code for your program.

  4. PRG 421 guide PRG 421 Week 2 Individual Assignment Retail Calculator PRG 421 Week 2 Supporting Activity Arrays and Combo Boxes • The application should include a Calculate button that, when pressed, computes and displays the sale price in a label or text field. • The program should allow the retailer to enter any number of items in this manner. • Include an Exit button to end the execution of the application. • How do arrays and combo boxes work together? Write a small program in which you add the elements of an array to a combo box and post the code for your program.

  5. PRG 421 guide PRG 421 Week 2 Supporting Activity Menus PRG 421 Week 3 Individual Assignment Individual Contact Information Program Part 1 and 2 • What are advantages of using menus in a GUI application? Design a menu structure for a program you would find useful in your work or hobbies.

Write the code for the try-catch block. Explain the activity and your code.

  7. PRG 421 guide PRG 421 Week 3 Supporting Activity Writing Code for a Data File PRG 421 Week 4 Individual Assignment. Pie Chart Applet • Think of a programming task—other than the individual or team assignments in this course—in which you would choose to use a data file. Write the code to read or write the file. Explain the activity and your code.. • Use a news article with statistics that are good candidates for a pie chart: for example, political candidate preferences; percentages of those for, against, or undecided about a ballot measure; and so forth. • Cite the source for your input statistics.

  8. PRG 421 guide PRG 421 Week 4 Learning Team Assignment (Charity Program) PRG 421 Week 4 Supporting Activity Java Applets and Network Security • Modify the program you created in Week Three to write the data—name, amount, and charity—into a sequential data file. • Implement a capability of reading what is in the existing data file and displaying it in the text area. • Select one of the applications you wrote in Week 1 or 2 and convert it to an applet. You may use either one of your individual assignments or an example of a full program you posted in response to a DQ. Explain why your individual assignment for Week 3 is not a good choice.

  9. PRG 421 guide PRG 421 Week 4 Supporting Activity Java Applets Versus JavaScript PRG 421 Week 5 Learning Team Assignment (Connect to Database, Charity Program) • Describe each user interface component used and how the applet uses each of them. • o Do you think the applet uses interface components effectively? Why or why not? • Discuss any challenges you encountered in making this conversion and successfully compiling and executing the applet. Post your applet code here.. • Modify the GUI to connect to this database and add entries to it and read entries from it. Entries read from the database should be displayed in the JTextArea or JTable.

You may choose to use either a text-based or a video tutorial. Follow the steps in the tutorial to learn how to use JavaDB. • Modify one of the demo programs with the JavaDB download to create and manipulate your own database. • What type of mobile app would you find useful? What steps would you take to create and deploy this app? Be specific about the software tools you would use. • Test and debug this final program.
