Document Summary

When you begin a journey, it"s a good idea to have a mental map of the terrain you"ll be passing through. The same is true for an intellectual journey, such as learning to write computer programs. In this case, you"ll need to know the basics of what computers are and how they work. You"ll want to have some idea of what a computer program is and how one is created. Since you will be writing programs in the java programming language, you"ll want to know something about that language in particular and about the modern, networked computing environment for which java is designed. As you read this chapter, don"t worry if you can"t understand everything in detail. (in fact, it would be impossible for you to learn all the details from the brief expositions in this chapter. ) Concentrate on learning enough about the big ideas to orient yourself, in preparation for the rest of the book.

Type of Errors For each of the following answer whether they would cause an compiler error, runtime error, or a bug. In other cases the mentioned error may not cause a problem for the computer and is merely a question of style. In this case you should choose "Style" In other cases the question may not cause a problem at all in which case you should answer "No Error" For the purpose of this question, you can use the following definitions: • Compiler error : An error that occurs during the compilation phase of your development. In this case no class file is produced. • Runtime error: An error that occurs while you are running your program. Your program starts to execute but terminates before the main method has finished executing. • Logical error or bug : An error that results in the wrong results being seen • Style error: The error does not make a difference to the computer but is something that may be considered bad code. 7. Omitting a semi-colon at the end of a variable assignment. (A) Compiler Error (B) Bug (logical) Error (C) Style (D) Runtime Error (E) No Error

Documentation & Requirements: 1. 5 pts. Write the file name, your name, email address and purpose of the program at the top of your source code in a
comment.
Example:
///////////////////////////////////////////////////////////////////////////////////////////////////
// Programmer: Thomas Gutierrez
// Email: [email protected]
// Purpose:
// Provides:
//////////////////////////////////////////////////////////////////////////////////////////////////
2. 5 pts. Add comments as appropriate throughout the program.
Program: 85pts.
This program will continue to build upon the Stocks Business Application program and transform it into a “Stocks” class. The
Assignment 5 solutions are recommended to be used as a starting point for this program. If the Assignment 5 solutions are not
used, refer to the Assignment 4 and 5 prompts for details.
The program must have the following requirements:
1. Create a Java Class named “Stock”.

2. The class should have at a minimum three private class variables:
o A variable for the stock name
o An array for the stock’s opening prices
o An array for the stock’s closing prices

3. This class should have two constructors:
o A “no argument” constructor.
o The parameterized constructor should take a parameter for the stock’s “name”.

4. Create the following set methods:
o setStockName: This method will initialize the stock’s name using the provided parameter MGMT330 – Assigment 6, 2

o setOpenPrices: This method will initialize the stock’s opening prices along with its size based on the provided
parameters – open prices and number of prices.
o setClosePrices: This method will initialize the stock’s closing prices along with its size based on the provided
parameters – close prices and number of prices.

5. Create the following get methods:
o getStockName: This method returns the stock’s name
o getOpenPrices: This method returns the stock’s opening prices
o getClosePrices: This method returns the stock’s closing prices
o getDayPrice: This method returns the price for a specific day for either the opening or closing price of the
stock. Parameters include the day and which price to return, e.g. “O” or “C”

6. Create a method named “percentChange” that computes the percentage change between an opening day price and a
closing day price. This method should have two parameters: 1) the opening day to use; 2) the closing day to use.

7. Create a method named “averageStockPrice” that computes the average of a stocks open or close prices. This method
should take a parameter that determines whether to compute the average for a stock opening or closing prices: “O”
or “C”.

8. Create a method named “displayPrices” that will neatly display a stock’s opening and closing prices for a certain
number of given days. The method should have a parameter for the number of days to display.

9. In the program’s “main” method:
o Create two “Stock” objects named: GME and GOOG
o Initialize each of the stocks opening and closing prices as follows:
 GME:
Opening 96.57 94.05 90.14 116 141
Closing 96.13 89.15 115.17 128.46 137.21

 GOOG:
Opening 2388.59 2455 2287.46 2342.3 2351.56
Closing 2465 2390.12 2300.41 2388.23 2299.33

o Compute the change in price for GME for opening price day 2 and closing price day 4 and print it out neatly
to the user.

o Display all opening and closing prices for GOOG, and display the average of both types of prices.
Extra Credit:
5pts. Build another stock object with 10 open and close prices. Display all information about the stock: percent change
between the first price and final closing price, display all prices, average stock price for both types of prices. The object and its
information should be created and displayed at the end of the main program. MGMT330 – Assigment 6, 3

Hints:
 All of Chapter 9 is useful for this program but the following sections cover the assignment: 9.2, 9.3, 9.4, 9.7, 9.9, 9.13
 Remember to indent your code properly.
 Scope will remain to be very important for variables when creating classes.

 Use previous assignment solutions for reference.

Hi. You should write a Java program to meet the specification shown below.

In this game(dice poker), the computer rolls two standard six-sided dice and you bet on the outcome. The outcome is the configuration of the numbers rolled (explanation below). The input/output should utilise a graphical user interface (input and message boxes).

1.1 Game flow

You start with some money in your bank. You play a number of rounds, where for each round you place a bet and the computer rolls the dice, checks results and modifies your bank balance. After certain conditions, the game ends and you're presented with some final information shown as a message box.

1.2 Placing bets

Before the computer rolls the dice, you can bet some money from your bank.

ˆ If the numbers are sequential (e.g. 1 and 2, 5 and 4, etc. Not 6 and 1), you earn double your bet.

ˆ If the numbers are identical (rolling doubles), you earn triple your bet.

ˆ Otherwise, you win nothing therefore you lose the amount of money you bet.

Before placing a bet, the computer should inform you of your current bank balance.

1.3 Starting Game- Game rules

When the game starts you are given £6 in your bank. Each bet costs £1 and you are allowed to make up to five bets before the game ends. The game will end if you run out of money, or you have no more attempts left (you made all five bets). At the end of the game, you will be told which of these conditions has ended the game.

1.4 Results display

Once the game has finished (all bets have been placed or you ran out of money) the computer will collate and display the results in a single message box, comprised by:

ˆ On row per bet, displaying your bet, the numbers rolled, the amount of money earned or lost for that bet.

ˆ One row at the end, displaying the amount of money that you have remaining in your bank at the end of the game.

1.5..Variable bet amount

Allow the user to change how much they would like to bet and change the amount you win accordingly. Allow bets between £1 and 4£ (integers only)

1.6.High score table

Create a high score table. The more money you have remaining in your bank at the end of the game the higher up the table you will be. In order to implement this, players will have to enter their name before they play. The high score table should be displayed as a separate message box after the results have been displayed at the end of the game(1.4)

Not1: Please use JoptionPane class instead of scanner class.

Not2: Also If possible explain the description of your classes: what each does and how they relate to each other. And if possible, program should be extensible. E.g. Is it easy to change the number of dice? The number of rounds to play? The sides of the dice?Etc.
