Assignment Details

Part 1
Modify your Java application so that it is an easy-to-use GUI application where all of the interaction is performed on one screen. You will now take the individual components and translate them to a single interactive GUI interface using the following GUI components, container, the event listeners, and event subclasses to enhance your application as a more GUI-appropriate interface:
• GUI components
• Container
• Event listeners
• Event subclasses (at least 3–4 utilized)
o ActionEvent
o ItemEvent
o FocusEvent
o KeyEvent
o MouseEvent
o WindowEvent
• ActionPerformed Method

Part 2
For this assignment, you are being asked to make sure you are exception handling by verifying that all of the customer-entered information is valid before the order is submitted to ensure order accuracy.
The customer information that the customer must now enter that should be validated includes the following:
• Entered username (must fill in a name)
• Entered at least one sub to order
• Selected all three attributes for sub (such as bread type, sub type, and sub size)
• Entered delivery address that includes street, city, state, and zip code
• Entered telephone number xxx-xxx-xxxx
In this assignment, you are adding in error handling to make sure the customer is filling in all of the required information.
To accomplish this task, you will be utilizing the following Java classes:
• Methods in the character class and StringBuilder class to validate and manipulate characters in a string
• Try.. Catch for the exception handling of all input fields

Continuing from the last assignment.
Use vector, wrapper classes, conversion, and collection data structures by writing and implementing Java code within your application that demonstrates each of these concepts.
Hint: These may be utilized in areas of storing items in the customer order so that you can allow the customer to order more than one sub or beverage.
Refer to the sample prototype for the various item lists you will use. Feel free to add more choices to each of these lists.

ITSD424 Unit 1 Famous Favorite Subs

We are developing this application
1. User will choose from menu item
2. User will review ordered items
3. Each item will have a unit price
4. Order details will show unit price plus total price
5. Use will Press order button to place order

For this Unit
Assignment Description
At this point, you are ready to start developing Java code to ask questions on customer information and the sub sandwich that customers want to order. You are only concerned with the functionality to request and provide feedback on what the customer entered.
Your main focus is on defining your classes and abstract classes and utilizing the concept of inheritance and polymorphism for the final sub the customer orders. You will first prompt for the customer name and delivery address, like in this sample that prompts for the customer name:

Then, you will prompt for the beverage, sub bread, sub type, and sub size.
You should present a message echoing back all of the information that the customer entered, similar to the following example presenting the customer’s name with a message:

Make sure you prompt for the four attributes (beverage, bread, type, and size) that you will need to request from the customer to define for the final sub and beverage selection. Also, be sure to comment all of your code to demonstrate that you understand what the code is doing.

CIS355A Week 5 Lab - File Processing Stocks4U

OBJECTIVES
• Add persistent data storage to your Week 4 Lab using text file input/output.

PROBLEM: Stocks4U Portfolio Management System
The portfolio management system you developed for Stocks4U needs the ability to save and restore a user’s data from a text file.

FUNCTIONAL REQUIREMENTS
You can code the GUI by hand or use NetBeans GUI Builder Interface.
You will enhance Week 4 GUI to include
• a File menu with menu items: open, save, exit; and
• a label to display total portfolio value.

Stock class
• Modify the toString of Stock class to display as
"Company: qty shares" (i.e., "Apple: 10 shares")

StockIO class
Create a StockIO class that is used to read from and write to a text file using an ArrayList. Make sure to use a delimiter between the fields; it does not have to be the # character. Example format of the file is:

Apple#100#55.0#80.0
Intel#50#75.0#70.0

This class should have two methods.
• getData - reads data from file, returns data in array list of stock objects
• saveData - writes data from an array list to the file in proper format
The file name will be an instance variable that you can set with a parameterized constructor, or with a separate method.

GUI class
Note that you will need to add an ArrayList to your GUI class to manage the data to/from the file. It will act as a parallel array to your DefaultListModel. Any time you add a stock, you must add it in BOTH places. Any time you remove a stock, you must remove it in BOTH places.

File - open should prompt for file name using JOptionPane, read the file and populate the JList.
File - save should prompt for file name to save data from JList to.
File - exit should exit the program.

The total value of the portfolio should be displayed at all times and updated anytime a stock is added or removed.

PRG/420 Week 5 Java 5.23 LAB: Adjust list by normalizing - methods

When analyzing data sets, such as data for human heights or for human weights, a common step is to adjust the data. This can be done by normalizing to values between 0 and 1, or throwing away outliers. For this program, adjust the values by subtracting the smallest value from all the values. The input begins with an integer indicating the number of integers that follow. Assume that the list will always contain less than 20 integers.

Ex: If the input is:
5 30 50 10 70 65
the output is:
20 40 0 60 55
For coding simplicity, follow every output value by a space, even the last one.

Your program must define and call a method:
public static int getMinimumInt(int[] listInts, int listSize)

Note: This is a lab from a previous chapter that now requires the use of a method.

PRG/420 Week 5 Java 5.22 LAB: Output values below an amount - methods

Write a program that first gets a list of integers from input. The input begins with an integer indicating the number of integers that follow. Then, get the last value from the input, and output all integers less than or equal to that value. Assume that the list will always contain less than 20 integers.

Ex: If the input is:
5 50 60 140 200 75 100
the output is:
50 60 75

The 5 indicates that there are five integers in the list, namely 50, 60, 140, 200, and 75. The 100 indicates that program should output all integers less than or equal to 100, so the program outputs 50, 60, and 75. For coding simplicity, follow every output value by a space, including the last one.
Such functionality is common on sites like Amazon, where a user can filter results. Write your code to define and use two methods:
public static void getUserValues(int[] myArr, int arrSize, Scanner scnr)
public static void outputIntsLessThanOrEqualToThreshold(int[] userValues, int userValsSize, int upperThreshold)

Utilizing methods will help to make main() very clean and intuitive.
Note: This is a lab from a previous chapter that now requires the use of methods.

PRG/420 Week 5 Java 5.21 LAB: Contact list

A contact list is a place where you can store a specific contact with other associated information such as a phone number, email address, birthday, etc. Write a program that first takes as input an integer N that represents the number of word pairs in the list to follow. Word pairs consist of a name and a phone number (both strings). That list is followed by a name, and your program should output the phone number associated with that name. Assume that the list will always contain less than 20 word pairs.

Ex: If the input is:
3 Joe 123-5432 Linda 983-4123 Frank 867-5309
Frank
the output is:
867-5309

Your program must define and call the following method. The return value of getPhoneNumber() is the phone number associated with the specific contact name.
public static String getPhoneNumber(String[] nameVec, String[] phoneNumberVec, String contactName, int arraySize)

Hint: Use two arrays: One for the string names, and the other for the string phone numbers.
