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.

PRG/420 Week 5 Java 5.19 LAB: Remove spaces - methods

Write a program that removes all spaces from the given input.
Ex: If the input is:
Hello my name is John.
the output is:
HellomynameisJohn.

Your program must define and call the following method. The method should return a string representing the input string without spaces.
public static String removeSpaces(String userString)

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

PRG/420 Week 5 Java 5.18 LAB: Flip a coin

Write a program that simulates flipping a coin to make decisions. The input is how many decisions are needed, and the output is either heads or tails. Assume the input is a value greater than 0.

Ex: If the input is:
3
the output is:
tails
heads
tails

For reproducibility needed for auto-grading, seed the program with a value of 2. In a real program, you would seed with the current time. In that case, every program's output would be different, which is what is desired but can't be auto-graded.

Note: A common student mistake is to create an instance of Random before each call to rand.nextInt(). But seeding should only be done once, at the start of the program, after which rand.nextInt() can be called any number of times.

Your program must define and call the following method that returns "heads' or 'tails".
public static String headsOrTails(Random rand)

PRG/420 Week 5 Java 5.17 LAB: Max magnitude

Write a method maxMagnitude() with two integer input parameters that returns the largest magnitude value. Use the method in a program that takes two integer inputs, and outputs the largest magnitude value.

Ex: If the inputs are:
5 7
the method returns:
7

Ex: If the inputs are:
-8 -2
the method returns:
-8

Note: The method does not just return the largest value, which for -8 -2 would be -2. Though not necessary, you may use the absolute value built-in math method.

Your program must define and call a method:
public static int maxMagnitude(int userVal1, int userVal2)

PRG/420 Week 5 Java 5.16 LAB: Step counter

A pedometer treats walking 2,000 steps as walking 1 mile. Write a program whose input is the number of steps, and whose output is the miles walked.

Output each floating-point value with two digits after the decimal point, which can be achieved as follows:
System.out.printf("%.2f", yourValue);

Ex: If the input is:
5345
the output is:
2.67

Your program must define and call a method:
public static double stepsToMiles(int userSteps)

CIS355A Week 4 Lab - Processing Arrays of Objects Stocks4U

OBJECTIVES
• Create a GUI that uses JList and JTabbedPanes.
• Process multiple objects in an ArrayList.
• Code event handlers for multiple events.

PROBLEM: Stocks4U Portfolio Management System
Stocks4U needs to develop an app for you to manage your stock purchases. You should be able to store a list of stock purchases, view the individual stocks, add and remove stocks.

FUNCTIONAL REQUIREMENTS
You can code the GUI by hand or use NetBeans GUI builder interface.

The GUI should have two tabs using JTabbedPane.
• One tab ("Show stocks") should have
 o a JList to display all the stock purchases;
 o a text field or label to display information about a particular stock; and
 o a JButton to remove a stock.
• One tab ("Add stock") should have textboxes, labels, and a button to input a stock.

Create a Stock class to manage the stock activity. It should have private instance variables of
• company name;
• number of shares;
• purchase price; and
• current price.
Create a default and parameterized constructor.
Create sets/gets for all instance variables.
Create a get method to calculate and return the profit or loss. This would be calculated as
 Number of shares * (current price – purchase price).
Create toString to display the name of the stock.

As you add stocks, they are displayed in the JList.
If you select an element in the JList, the gain or loss is displayed in the label or text field.
If you select an element in the JList and click Remove, the stock is removed from the list.

GRADING RUBRIC
Stock class
• Has all required functionality 15
GUI class
• Use the Stock class to process data.
• As you add stocks, they are displayed in the JList.
• If you select an element in the JList, the gain or loss is displayed in the label or text field.
• If you select an element in the JList and click Remove, the stock is removed from the list.
• Use error messages for any invalid/missing user input using JOptionPane. 25

PRG/420 Week 4 Java 4.15 LAB: Elements in a range

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. Assume that the list will always contain fewer than 20 integers.
That list is followed by two more integers representing lower and upper bounds of a range. Your program should output all integers from the list that are within that range (inclusive of the bounds). For coding simplicity, follow each output integer by a space, even the last one. The output ends with a newline.

Ex: If the input is:
5 25 51 0 200 33 0 50
then the output is:
25 0 33
(the bounds are 0-50, so 51 and 200 are out of range and thus not output).
To achieve the above, first read the list of integers into an array.

PRG/420 Week 3 Java 3.11 LAB: Mad Lib - Loops

Mad Libs are activities that have a person provide various words, which are then used to complete a short story in unexpected (and hopefully funny) ways.

Write a program that takes a string and integer as input, and outputs a sentence using those items as below. The program repeats until the input string is quit 0.

Ex: If the input is:
apples 5
shoes 2
quit 0

the output is:
Eating 5 apples a day keeps the doctor away.
Eating 2 shoes a day keeps the doctor away.

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

CIS355A Week 3 Lab - Enhanced GUI Application using Additional Swing Components

OBJECTIVES
• Create a GUI that uses JCheckBox, JRadioButton, JTextArea, and menus.
• Process multiple events.

PROBLEM: BurgersRUs Point of Sale system
Burger Barn needs a point of sale application. The products and prices are as follows.
Burgers: single $3.50, double $4.75
Add cheese: +$.50
Add bacon: +$1.25
Make it a meal: +$4.00

FUNCTIONAL REQUIREMENTS
You can code the GUI by hand or use NetBeans GUI builder interface.
The GUI should use JRadioButton to choose single or double burger.
• Single burger
• Double burger
It should use JCheckBox for add ons.
• Add cheese
• Add bacon
• Make it a meal
JTextField for item price, order quantity, order total
JTextArea to display the receipt
Create a menu with the following options.
File  Order
Exit  Add to Order
  Clear for next item
  New Order

As the user selects items, the item price should be calculated and updated accordingly.
Note that quantity should default to 1. The user can change if needed.
Once choices are made and quantity is entered, process the order using the menu options.
Order—Add  to Order Displays the choice and price in each text area.
   Note that multiple items can accumulate in a single order Updates the order total
Order—Clear for next item Clears the checkboxes. Note that quantity should default to 1
Order—New  Order Clears the GUI and totals for a new order
File—Exit  Exits the program. Use System.exit(0) commad.

GRADING RUBRIC
