Software Engineering
Application: Animal Characteristics
In today’s fast-paced world, it is important for programmers to think about potential future changes that impact their programs. One way that software developers can address this concern is by designing programs that are easy to upgrade and are adaptable to new technologies. In this Application, you work toward this goal by writing a program that uses the concept of inheritance to allow for later additions.
For this Application:
Create a program using the principles of inheritance based on the following scenario:
Scenario: The teachers of a local school need a program to teach their students the basics about animals and their characteristics. The teachers want the program to contain a database of animals, from which the teachers can choose animals to add to a list. The list will be displayed on the students’ monitors so they can study the animals and their characteristics. Right now, the teachers want a program that handles only mammals and birds, but in the future they may want to add other types of animals. The teachers also expect the program to run smoothly and be thoroughly tested to handle extraneous input.
Create a program that fulfills the specifications outlined in the scenario above. Use the concept of inheritance to allow for later additions to the program. Also use the TDD concepts from Unit 1 to test the program as you go.
Follow the steps below to create the program:
Create a class Animal with these variables:
• public String kind;
• public String integument;
Add these methods:
• public String movement(boolean fast) returns one of the two strings “I walk on four legs.” or “I run on four legs.” depending on whether fast is false or true, respectively.
• public String sound() returns the empty string.
Create two classes, Mammal and Bird, each of which extends Animal.
In the constructor for Mammal, set the variable integument to the string “hair”. Do not declare the variable again; it has already been declared in Animal. Similarly, in the constructor for Bird, set integument to the string “feathers”.
In the Bird class, override the movement method to return either “I walk on two legs.” or “I fly.” depending on the setting of the fast parameter. Use the @Override annotation.
Create additional classes to represent specific kinds of animals (each extends either Mammal or Bird). In each class, set the kind variable and override the sound() method. For example, you might create a Duck class, setting the kind to “duck” and overriding the sound() method to return the string “„quack?” (in single quotes).
Note: Remember to test the methods as you go. Use the principles of TDD that you examined in Unit 1. The methods you write in this program are simple and only return strings, so they are relatively easy to test.
Users should be able to create animals of any kind you have defined (duck, cow, etc.), but you should also prevent the user from creating a “plain” animal, because there’s no such thing. Every animal has to be a specific kind. Do this by writing a factory method in the Animal class-that is, a method to create objects of various animal kinds. Here’s how:
• First, prevent users from creating a “plain” animal by writing a no-argument constructor for Animal, but making it private.
• Second, write a method Animal newInstance(String kind) that takes the desired kind of animal (such as “duck”), calls the constructor for that particular kind of animal, and returns the result. If given an unrecognized string, the method should not crash; it should return null.
Your test of the newInstance method must verify that the objects it creates are equal to objects created by calling the appropriate constructor (for instance, new Duck()) directly. Testing equality (that is, calling assertEquals) requires an equals method in the Animal class. There are five different characteristics that should be equal for two animals to be equal-their kinds, their integuments, their slow and fast movements, and the sounds they make. You don’t need to test for every kind of animal you define, but you should test at least one kind of bird and one kind of mammal. Also, don’t forget to test the newInstance method with an unrecognized (or misspelled) kind of animal.
Write a print method in your Animal class. When called, it should print out all the information about “this” animal, for instance:
I am a duck.
I have feathers.
When I go slowly, I walk on two legs. When I go fast, I fly.
The sound I make is „quack?.
Note that the sound of the animal has single quotes around it when you see it displayed in the output of your program. The sound method returns a string which contains a single quote, the sound, and then another single quote.
Write a class called AnimalStuff containing a main method. In this class, define an
ArrayList of Animal.
In case you are not familiar with ArrayList, you need to import java.util.ArrayList and your declaration should look something like
ArrayList<Animal> myList = new ArrayList<Animal>();
Although a normal array has a fixed size which you specify, an ArrayList does not and can grow as elements are added to it. You can find more information about ArrayList in the Java API.
An ArrayList<Animal> can hold a mixture of all kinds of animals.
Finally, in your main class, write a loop asking the user which of three things to do: Add an animal of a chosen type to the list, print (every animal in) the list, or quit the program. If the user asks for an animal your program doesn’t recognize, don’t add null to the list, but do inform the user of the problem.
Use a Scanner (import java.util.Scanner) to read input from the user. First, create a Scanner object:
Scanner scanner = new Scanner(System.in);
Then, to read a word typed in by the user, you can use the following:
String word = scanner.next();
To read in an entire line, use:
String line = scanner.nextLine();
To read in an integer, use:
int number = scanner.nextInt();
To read in a floating-point number, say:
double fpNumber = scanner.nextDouble();
Include screenshots of your program running as part of your submission. Show five valid animals being added and two invalid animals trying to be added. Also show screenshots of the printed list after each animal is added. Include screenshots of your program being tested with JUnit.
The legislative branch enacts legislation
The legislative branch enacts legislation

Article
Our job as IT security professionals is to ensure an ethical approach to the safety and integrity of the data. We have been given laws to guide us on the path of ethics.
Laws were crafted to provide an entity the ability to prosecute those that hack them. A problem with the laws is that it also covers the illegal activities of those entities that are being hacked. When the entities go beyond their original scope of intent, their intentions are for selfish gain.
The entities must be put back in check, which is why groups like Anonymous have risen. On Anonymous’ website it states, “We always fight for people rights. We want every citizens of the world is equal. We harm anyone at any time who doing wrong things” (anonymoushackers.net, 2017)
The idea of keeping powers in check reminds me of how our nation’s founding fathers setup the three branches of government. The three branches are, “The legislative Branch enacts legislation” (usa.gov), while “The executive branch carries out and enforces laws” (usa.gov) and “The judicial branch interprets the meaning of laws” (usa.gov).
They are designed to keep each other in check and prevent one from becoming more power than the other. The integrity of the three controlling government bodies is only as good as the integrity of the members. This can be said of any government of the world. Anonymous is a self-appointed group for unofficial checks and balances for the governments of the world.
I do have reservations about the information Anonymous is presenting to the world, which is the integrity of that evidence. Is it being modified to make it more juicy and enticing? Can power corrupt? The 1st Baron Acton seemed to think so when he said, “Power tends to corrupt, and absolute power corrupts absolutely” (Britannica, 2012).
This does not mean anyone in power is corrupt, it just means that there is a greater chance with the more power they have. God himself has his own system of ethical checks and balances.
Jesus says in Luke 8:17, “For there is nothing hidden that will not be disclosed, and nothing concealed that will not be known or brought out into the open” (NIV, 2011).

International Business Letter
about ¾ of a page to one full page business letter(formatting as researched culture may dictate) + several paragraphs of rationale
One of the great things about entering a field under the sphere of business is that you’ll get to encounter people from all over the world. Because of this plethora of diversity, it’s important to understand the nuances and intricacies that comprise different cultures and to be aware about how your own cultural makeup will interact with those of others, especially with regards to business etiquette.
Please ponder a country that you find intriguing and/or a country where you can foresee yourself conducting business. Please do some research on the culture and etiquette of this country, especially with regards to the customs related to the ways this country conducts business. Some questions to ponder: how are gender relations handled? Will a more direct or indirect approach be appropriate when making a business proposal? Is the country high-context or low-context? How are public-figures perceived by the general public—are they beloved? Are they despised? How personal should you get when doing business?
I. Once you’ve researched business etiquette in this country, write a business-letter to either a potential business partner in that country or the embassy proposing some sort of business idea. In the letter you must convey proper respect for the elements of business etiquette within that country by manifesting what you’ve learned.
In other words, incorporate the ideas you learned into the letter and write the letter as would be expected in that country. You want to sound as natural as possible when expressing that you’ve done some research on customs. For example: if a country is high context, how will that effect the way you write a business letter?
II. After you write this letter, please briefly explain why you wrote the way that you did. Essentially, explain to me what you discovered (or perhaps already knew) about the business customs of the country you want to work with.
Side-notes: I encourage you to use this assignment to explore the customs a new country that you may be interested in but aren’t necessarily familiar with. That is, if you were born in Sweden and identify as Swedish, I’d urge you to avoid writing about Sweden and opt for a country you don’t know much about.
While I encourage you to search far and wide for info on other countries, www.geert-hofstede.com is a fantastic resource.
