 CIS331 – Ch. 9 and 10 Exercise: Class BankAccount You are going to code and use a simple little bank account Class called BankAccount. The idea here is that instance objects of this class will represent separate bank accounts for customers. Here are your details: Part 1: Build the Class Data Fields: int accountID, String accountOwner, double accountBalance: all public. Constructors and Member Methods: On these, I will leave it up to your group to discuss return types, access specifiers, and logic except where noted. Remember that constructors have the primary job of giving your instance object’s data fields their starting values. BankAccount() BankAccount(String accountOwner, double accountBalance) A “setter” method for accountOwner A “getter” method each for accountBalance and account Owner makeTransaction(double amount) It will add the amount to the account Balance data field. The value of amount could be positive or negative. If the accountBalance data field becomes <=0.0 due to this transaction, print a message stating that the account is overdrawn. Part 2: Use the Class Create an instance object of your BankAccount class. Initialize it with whatever customer name and balance you want to use in the constructor invocation. Make 3-4 transactions of positive and negative amounts. Print out the status of the account like so: Example: Owner: Suzy, Balance: $3445.32 Part 3: Store Transaction History Enhance your BankAccount class so that you can store a history of transactions made on each account. Create a new class, called Transaction that will simply store an amount and a description of the transaction. Create only a full constructor for the class (no 0-arg constructor is needed) To your BankAccount class, add an array of Transaction objects. Give the array a size of 100 in your constructors. Add any additional data field(s) that are needed to help manage the array and where new Transactions will be stored. Each BankAccount will have its own Transaction array. • Modify the makeTransaction() method from earlier so it accepts both an amount and description. The method should now create a new Transaction object and store it in the BankAccount's array. Correct any errors in your Application that result from these changes. 

Define a method called exactChange that takes the total change amount in cents and an integer array as parameters. Method exactChange() calculates the change using the fewest coins and stores the number of each coin type used into the array parameter. Index 0-3 of the array parameter should contain the number of pennies, nickels, dimes, and quarters respectively. Then write a main program that reads the total change amount as an integer input, calls exactChange(), and outputs the change, one coin type per line. Use singular and plural coin names as appropriate, like 1 penny vs. 2 pennies. Output “no change” if the input is 0 or less.

Ex: If the input is:

0

(or less), the output is: 

no change

We learn from our readings that the use of mobile devices in our society today has indeed become ubiquitous.  In addition, CTIA asserted that over 326 million mobile devices were in use within The United States as of December 2012 – an estimated growth of more than 100 percent penetration rate with users carrying more than one device with notable continues growth.  From this research, it’s evident that mobile computing has vastly accelerated in popularity over the last decade due to several factors noted by the authors in our chapter reading. In consideration with this revelation, identify and name these factors, and provide a brief discussion about them.

Please make your initial post substantive. A substantive post will do at least two of the following:

• Ask an interesting, thoughtful question pertaining to the topic
• Answer a question (in detail) posted by another student or the instructor
• Provide extensive additional information on the topic
• Explain, define, or analyze the topic in detail
• Share an applicable personal experience
• Provide an outside source (for example, an article from the UC Library) that applies to the topic, along with additional information about the topic or the source (please cite properly in APA)
• Make an argument concerning the topic.

At least two scholarly source should be used in the initial discussion thread. Be sure to use information from your readings and other sources from the UC Library. Use proper citations and references in your post.

Monte Carlo Simulation Project 

Introduction 

A great tool for investigating uncertainty in a complex process is the Monte Carlo simulation. If you’d like, there is plenty of information online that describes what this simulation does and what it is useful for. But in brief, a Monte  Carlo simulation aims to simulate the possible pathway of a future endeavor, experiment, or process, given multiple inputs that each have uncertainty. Monte  Carlo simulations are oftentimes used by financial planners to try to predict that might happen in the future. Inputs to financial planning processes include probabilities of how the stock market might do, projections for various costs and amount of sales, and many other financial variables. In the sciences, there may be several or many inputs into a future process, and the goal is to understand the likelihood of a scenario going one way or another.

In this project, you will first learn about a Monte Carlo simulation and how to implement it in a VBA user form using an example investigating a cookies recipe, where each of the ingredients has an uncertainty associated with it . You will explore five different typical distributions used in Monte Carlo simulations and implement these into the VBA user form. Finally, you will adapt a profitability analysis example into the main project deliverable, which is a user form that allows the user to simulate a profitability analysis based on net present value (NPV) of a proposed capital project.
