PRG/421 Week 2 Java Lab 2.22 LAB: Parsing dates

Complete main() to read dates from input, one date per line. Each date's format must be as follows: March 1, 1990. Any date not following that format is incorrect and should be ignored. Use the substring() method to parse the string and extract the date. The input ends with -1 on a line alone. Output each correct date as: 3/1/1990.

Ex: If the input is:
March 1, 1990
April 2 1995
7/15/20
December 13, 2003
-1

then the output is:
3/1/1990
12/13/2003

PRG/421 Week 3 Java 3.20 LAB: Book information (overriding member methods)

Given main() and a base Book class, define a derived class called Encyclopedia. Within the derived Encyclopedia class, define a printInfo() method that overrides the Book class' printInfo() method by printing not only the title, author, publisher, and publication date, but also the edition and number of volumes.

Ex. If the input is:
The Hobbit
J. R. R. Tolkien
George Allen & Unwin
21 September 1937
The Illustrated Encyclopedia of the Universe
James W. Guthrie
Watson-Guptill
2001

Number of Volumes: 1

Note: Indentations use 3 spaces.

PRG/421 Week 3 Lab 3.17 LAB: Pet information (derived classes)

The base class Pet has private fields petName, and petAge. The derived class Dog extends the Pet class and includes a private field for dogBreed. Complete main() to:
- create a generic pet and print information using printInfo().
- create a Dog pet, use printInfo() to print information, and add a statement to print the dog's breed using the getBreed() method.

Ex. If the input is:
Dobby
2
Kreacher
3
German Schnauzer

The output is:
Pet Information:
Name: Dobby
Age: 2
Pet Information:
Name: Kreacher
Age: 3
Breed: German Schnauzer

PRG/421 Week 4 Java 4.15 LAB: Ticketing service (Queue)

Given main, complete the program to add people to a queue. The program should read in a list of people's names including "You" (ending with -1), adding each person to the peopleInQueue queue. Then, remove each person from the queue until "You" is at the head of the queue. Include print statements as shown in the example below.

Ex. If the input is
Zadie Smith
Tom Sawyer
You
Louisa Alcott
-1

the output is
Welcome to the ticketing service...
You are number 3 in the queue.
Zadie Smith has purchased a ticket.
You are now number 2
Tom Sawyer has purchased a ticket.
You are now number 1
You can now purchase your ticket!

PRG/421 Week 4 Java 4.14 LAB: Student grades (HashMap)

Given a HashMap pre-filled with student names as keys and grades as values, complete main() by reading in the name of a student, outputting their original grade, and then reading in and outputting their new grade.

Ex: If the input is
Quincy Wraight
73.1

the output is
Quincy Wraight's original grade: 65.4
Quincy Wraight's new grade: 73.1

CIS355A Week 6 Lab - Database Connectivity Student Management System

OBJECTIVES
• Programmatic access to a MySQL database to add and display records

PROBLEM: Student Management System
A teacher needs the ability to store and retrieve student data. This includes
• student name;
• three test scores;
• average; and
• letter grade.

FUNCTIONAL REQUIREMENTS
You can code the GUI by hand or use NetBeans GUI builder interface.
Create a GUI which allows for input and display of student data.
It should include buttons to save a record, display all records.

Create a database and table to store student name and three test scores. (Note that average and grade are calculated by app.)

Student class
Create a Student class to manage the student data. It should have private instance variables of
• student name; and
• three test scores.
The class must have the following methods.
• A default and parameterized constructor
• Sets/gets for all instance variables
• A get method to calculate and return the average
• A get method to calculate and return the letter grade
• toString to display the name of the student

StudentDB class
Create a StudentDB class that is used to create a connection and interface with the database.

This class should have two methods.
• getAll - reads data from database, returns data in an arraylist of student objects
• add - writes a record to the database

GUI class
Insert button will take the info from the GUI (student name and three test scores) and insert a record into the table.  Input should be cleared from the textboxes.
Display button will read the data from the database and creates a report in Console window, sample format below.
Name Test1 Test2 Test3 Avg Grade
Bruce Wayne  90  95  98  94.3  A
Clark Kent  65  70  90  75.0  C

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.

RUBRIC
Stock class toString modified 5
GUI class
• Menu is added.
• Label is added for total portfolio value.
• Open menu item reads data from a file and displays in list box.
• Save menu item writes data to a text file in proper format.
• Total value is updated whenever any changes are made to stocks (add, remove, open a new file). 15

• getData method reads from file to array list
• saveData method writes from array list to file 20

PRG/420 Week 5 Java 5.20 LAB: Acronyms

An acronym is a word formed from the initial letters of words in a set phrase. Write a program whose input is a phrase and whose output is an acronym of the input. If a word begins with a lower case letter, don't include that letter in the acronym. Assume there will be at least one upper case letter in the input.

Ex: If the input is Institute of Electrical and Electronics Engineers, the output should be:
IEEE

Your program must define and call a method thats returns the acronym created for the given userPhrase.
public static String CreateAcronym(String userPhrase)

Hint: Refer to the ascii table to make sure a letter is upper case.
