DISCUSSION QUESTION # 2
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.
DISCUSSION QUESTION # 3
What are the advantages and disadvantages of sequential and random access files?
Provide an example in which a sequential file is a better choice than a random access file. Explain why.
Provide an example in which a random access file is better than a sequential file. Explain why.
LEARNING TEAM
Create a GUI-based program to accept name of donor, name of charity, and amount of pledge from the user.
Display a list of entries in a JTextArea or JTable.
Submit the .java source file for this program.
INDIVIDUAL ASSIGNMENT
This is a two-part assignment.
Part 1
Design, implement, test, and debug a program with a JFrame that allows the user to enter a series of contacts’ names, ages, e-mail addresses, and cell phone numbers, and creates a file from the entered data. Validate the age entry to ensure that it is numeric and between 0 and 120. Include information for three to five contacts.
Part 2
Design, implement, test, and debug a program that reads the file you created by the list in Part 1 and displays the records in a JFrame. You may either display all entries in the list at once or display them one at a time; the user interface is up to you. Protect against not being able to open the file.
Week 4: Applets and Graphics
WEEK 4
DISCUSSION QUESTION # 1
What are three ways Java® applets enhance network security? Describe how each is used and how it affects security.
DISCUSSION QUESTION # 2
How would you differentiate a website that uses a Java® applet from one that uses JavaScript® code? Locate a website that includes a Java® applet and provide its URL.
Describe each user interface component used and how the applet uses each of them.
Do you think the applet uses interface components effectively? Why or why not?.
INDIVIDUAL ASSIGNMENT
Write an applet that includes a pie chart.
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.
Week 5: Database Connectivity and Mobile Computing
DISCUSSION QUESTION # 1
Conduct an Internet search for JavaDB tutorial. 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.
Write a 200- to 300-word description of the challenges you encountered.
Post the source code of your program.
DISCUSSION QUESTION # 2
What type of mobile app would you find useful? What steps would you take to create and deploy this app?
Write a program to create a database from the data in the sequential file you created in Week Four.
LEARNING TEAM ASSIGNMENT
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.
Test and debug this final program.
