Create an Invoice class with 4 attributes: PartNumber (type int), PartDescription (type String), Quantity (type int), and Price (type double). Create a constructor that allows you to initialize all 4 attributes from values passed in as parameters. Override the toString() method to display all 4 attributes in a format of your choosing. Create a List of 10 Invoices containing data of your choosing. Use lambdas and streams to perform the following queries on the list of Invoice objects and display the results: Sort the Invoice objects by PartDescription, then display the results. Sort the Invoice objects by Price, then display the results. Map each Invoice to its PartDescription and Quantity, sort the results by Quantity, then display the results. Map each Invoice to its PartDescription and the value of the Invoice (i.e., Quantity * Price). Order the results by Invoice value. Modify Part (d) above to select the Invoice values in the range of $200 to $500 (inclusive) and display the results separately.
The code I have. Need help on this code to demonstrate the use of lambdas and streams.

Exception Handling
You decide to upload your recent project to a programming community website for feedback, and one thing that community users keep pointing to is the lack of exception handling. Realizing that they are correct, you decide to rectify the situation and improve your programs… or at least one of them. Take one of the programs you designed over the past couple of weeks and enhance the program with exception handling code. Your program should incorporate the TRY and EXCEPT blocks and handle any errors and exceptions that you can find.
For this project:
Tips: Exception handling programming takes a bit of forethought. Think about ways that you can make your program malfunction while using it (not by changing the code).
Except in cases that involve fraud, control deficiencies should generally be reported to:
Question 4 options:
the external auditors
law enforcement
the board of directors
the person directly responsible for the controls operation
senior management at all levels of the organization

You are a consultant for the Diligent Consulting Group (DCG). You have completed the first assignment, developing and testing a forecasting method that uses Linear Regression (LR) techniques (Module 2 Case). However, the consulting manager at DCG wants to try a different forecasting method as well.
Now you decide to try Single Exponential Smoothing (SES) to forecast sales.
Using this Excel template below. then do the following:
Calculate the MAPE for Year 2 Linear Regression forecast (use the first spreadsheet tab labeled “Year 2 Forecast – MAPE”).
Calculate forecasted sales for Year 2 using SES (use the second spreadsheet tab labeled “SES – MAPE”). Use 0.15 and 0.90 alphas.
Compare the MAPE calculated for the LR forecast (#1 above) with the MAPEs calculated using SES.
(2 pages)
write a report to your boss in which you discuss the results obtained above. Using calculated MAPE values,make a recommendation concerning which method appears to be more accurate for the Year 2 data: SES or Linear Regression.
EXCEL
Using the customer traffic data and matching sales for each month of Year 1, create a Linear Regression (LR) equation in Excel, assuming all assumptions for linear regression have been met. Use the Excel template provided (see “Module 2 Case – LR –Year 1” spreadsheet tab), and be sure to include your LR chart (with a trend line) where noted. Also, be sure that you include the LR formula within your chart.
After you have developed the LR equation above, you will use the LR equation to forecast sales for Year 2 (see the second Excel spreadsheet tab labeled “Year 2 Forecast”). You will note that the customer has collected customer traffic data for Year 2. Your role is to complete the sales forecast using the LR equation from Step 1 above.
After you have forecast Year 2 sales, your Professor will provide you with 12 months of actual sales data for Year 2. You will compare the sales forecast with the actual sales for Year 2, noting the monthly and average (total) variances from forecast to actual sales.
(4 pages)Written Report
write a report for the client that describes the process you used above, and that analyzes the results for Year 2.
(What is the difference between forecast vs. actual sales for Year 2—by month and for the year as a whole?)
Make a recommendation concerning how the LR equation might be used by New Star Grocery Company to forecast future sales.

M4D1: Ethical Breaches
In this module, we will explore the concepts presented in the readings and look for examples in our own lives (personal and professional) to illustrate (or disprove) them. It seems as if ethical breeches are all around us. The media is replete with stories of how senior leaders in the military, government, business, and industry are exercising bad judgment. These are people who seemingly have it all and should be beyond reproach. We will examine why some individuals exercise good judgement while others turn to corruption. It is important to take things apart, look at them and become aware of what they mean for us as human beings, leaders, and members of organizations and communities.
Let’s turn our attention to a discussion about the ethical concepts presented in this module and share some examples within our own organizations.

Module 5: Module Notes: “Good” Versus “Bad” Lying
In school we were taught the famous legend of George Washington, who, as a youth, could not tell a lie when he admitted to chopping down a cherry tree belonging to his father. Whether or not the legend is true is not as important as the lesson it is supposed to communicate: that honesty is an important trait of anyone, but especially of a leader. As we examine the issue of lying in this module, there are several questions that we will encounter: What is a lie? How do we know that lying is wrong? Are there reasonable excuses or rationales for lying? And is it ever acceptable for a public official to lie in the performance of his or her official duties?
In her classic book, Lying, Sissela Bok cites the absolutist position of the 18th century philosopher Immanuel Kant (Links to an external site.)Links to an external site., “Truthfulness in statements which cannot be avoided in the formal duty of an individual to everyone, however great may be the disadvantage accruing to himself or to another” (Bok, 1989) (p.38) Bok goes on to argue that “most have held the contrary view—that there are times when truthfulness causes or fails to avert such great harm that a lie is clearly justifiable” (p. 39). She further argues that this position leads to another problem: “The more difficult task remains: That of drawing lines.” (p.46)
This module is about where other people have drawn those lines—and more importantly about where you draw those lines. You will read several case studies and score them on whether or not you believe the central characters’ decision was right or wrong. By scoring the rightness or wrongness of the actions taken in the mini-cases, you are also revealing your own preferences as reflected in your scores in the Ethical Type Indicator. After you have scored the mini-cases, read the piece by Dobel and then revisit the cases to see if you might have changed your thinking.
Your assigned readings should be read in the following order:
The nineteenth-century philosopher Jeremy Bentham (Links to an external site.)Links to an external site. stated a lie that is not accompanied by “any other material circumstances,” nor does not produce “any material effects” is really not offensive at all. It would be difficult to compose ethical rules to cover a multitude (infinite really) of situations in which people lie. With this in mind, we might proclaim that lies are relative and can only be judged against the set of circumstances in which they occur. The relativist probably determines that lying is then ethically neutral, depending on the circumstances. On the other hand, Bentham goes on to state that lying would be instrumental in producing “pernicious effects.” What kind of “pernicious effects” does lying produce? Think about how you might feel should you be on the receiving end of a lie. Maybe it is not harmful to anyone, but once you discover that someone has purposely lied to you, you become suspicious and trust is, if not destroyed, then at least damaged. If lying was acceptable all the time, how would we be able to tell what is truth? In such a society, suspicion, mistrust, and cynicism would undoubtedly underlie all of our personal and professional relationships.
Although it is somewhat easy to identify situations where lying is wrong, can we also identify situations where lying is acceptable? Don’t we all lie, especially to save another’s hurt feelings? How about those white lies we use to get out of or over a commitment? Are those kind of lies acceptable to most people? We would certainly say that lying to save a life would be a “good” lie.
Once we agree that some forms of lying are “good” versus “bad,” then the question becomes one of drawing lines rather than of absolutes. But what is a lie if not an absolute? We know when we are lying and admittedly some people are actually very good at it. The website dictionary.com gives the definition of the word lie as “a false statement made with deliberate intent to deceive.” This definition points to the speaker’s intentions. Intentions though can depend on who is asking the question, how it is asked, and in what context. It is sometimes difficult to tell if there is a conscious attempt to deceive or if it was just a misunderstanding of what was meant. Politicians use this technique often, taking back what you think they said or being purposely vague. There are also examples of candidates making promises they don’t know if they can or will keep or diplomats telling each other of their countries’ mutual admiration for each other.
In this module, you will read some small case studies, called mini-cases that will require you to analyze ethical dilemmas. These dilemmas require you to take a position of right or wrong but to also discuss when, if ever, deception is justified. As a public service professional, you will be confronted with extremes of right and wrong but you will also face several situations in which the rightness and wrongness may not be so obvious. The purpose of this exercise is to help you clarify and improve the reasoning process that leads to ethical decision making. It is also important to examine considerations upon which your judgments rest, the inconsistencies or contradictions, and to bring out unconsidered arguments that might alter your judgments or at least lay the framework to formulate guidelines to make difficult ethical choices.
