Task 1

For this task you will create a Subject class, whose instances will represent the subjects for study at a university. A subject will have a name, just a String, and a subject code, which is a six-character String. The first three characters of a subject code are alphabetic and the last three are numeric. The first three characters define the subject’s discipline area. A subject code must be unique.

You will also write a TestSubject class to test the use of your Subject class. In particular this will maintain an array of subjects. In order to manage the uniqueness of the subject codes, your program will need to display information about existing subject codes as well as checking that any new subject code supplied by the user is not the same as any existing subject code.

The following state and functionality should be provided for the Subject class:

• Two fields will hold the subject’s name and the six-character subject code.
• A constructor will allow a name and a new, validated subject code to be provided when a new subject is created.
• Getters will provide access to the attributes.
• An accessor method called getDiscipline will return a string containing the first three characters of the subject code.
• Another accessor method called codeMatches will return a boolean value indicating if the subject’s code matches the string argument provided. “Matches” is used here in the same sense as for the matches method of the String class.
• A toString method will return a string containing the subject code and subject name.

To assist with managing subject codes and their uniqueness you will provide the Subject class with some class methods as follows:

• An allDisciplines method will accept an array of Subject objects. It will return an array containing the different 3-character discipline codes represented in the array of subjects in alphabetically order. 
• A codesPerDiscipline method will accept an array of Subject objects and a 3-character discipline code. It will return an array containing the different subject codes represented in the array of subjects for the particular discipline.
• An isValidCode method will accept a string that is a possible new subject code, and return a boolean indicating whether it satisfies the structural requirements for a subject code.
• A codeExists method will accept an array of Subject objects and a possible new subject code. It will return a boolean indicating whether that code has already been allocated to one of the subjects in the array.
• A sortDisciplines method will accept an array of Subjects objects. It will return the sorted array of subjects in alphabetically order.  

Your TestSubject program will perform the following sequence of actions, using good design techniques such as in the appropriate use of methods:

• An initial array of Subject objects will be created from any data in a file that was previously saved by the program.
• The user interaction will then proceed to allow the user to add one or more new subjects to the array. If the user wishes to add new subjects, the discipline areas of existing subjects should be displayed in alphabetically order. The user will then enter a discipline code to which the program will respond by displaying any existing subject codes in that discipline. This procedure simplifies the user’s task of choosing subject codes that do not already exist, but does not prevent user mistake. Each subject code entered by the user should be checked. The user can enter any new subjects in that discipline (or indeed in other disciplines). The user should be given the choice of repeating the processing for other discipline areas.
• When the user has finished adding subjects, and only if subjects have indeed been added, the program will overwrite the data file with the updated data.

Note:

• You may use an ArrayList to implement an array if you prefer and it is appropriate.

Material to submit

The material to submit for each task is described in the section Assessment Information in this Subject Outline, under the heading Presentation.

Task 2

• Person: A Person contains a first name, last name, street address, zip code, and phone number. The class also includes a method that sets each data field and display method that displays all of a Person’s information.
• CollegeEmployee: CollegeEmployee descends from Person. A CollegeEmployee also includes a Social Security number, an annual salary, and a department name, as well as methods that override the Person methods to accept and display all collegeEmployee data.
• Faculty: Faculty descends from ColegeEmployee. This class also includes a Boolean field that indicates whether the Faculty member is permanent, as well as methods that override the CollegeEmployee methods to accept and display this additional piece of information.
• Student: Student descends from Person. In addition to the fields available in Person, a Student contains a major field of study and a grade point average as well as methods that override the Person methods to accept and display these additional facts.

Directions: In this module you read about specialized cell types called guard cells. These cells are usually found on the bottom side of the leaf and control the size of stomata (“holes” in the leaf where gas exchange occurs). Think about the following questions in regards to these structures:

1)What is the purpose of having these “holes”? What gases enter/ exit this hole? The guard cells control the size of the stomata by swelling and shrinking.

2) What is the mechanism for the swelling and shrinking that take place here? (Hint: Guard cells are specialized cells that have a plasma membrane barrier and the ability to control the solute level inside/ outside of the cell.)

Directions:  In this module, you are learning about the cell cycle, mitosis and meiosis. While the chapter describes how meiosis normally proceeds, it is important to note that mistakes can happen. Let’s look at the animal life cycle for example. Sometimes mistakes can happen in the way the duplicated chromosomes are separated and this can lead to gametes (sex cells: eggs and sperm) that contain more or less of a particular chromosome. Non-disjunction is the failure of chromosome pairs or sister chromatids to separate properly.

As you can imagine whether this happens during the first division of meiosis or the second, the event changes the total chromosome number for a given gamete. An example of one syndrome related to chromosome number abnormality is Down Syndrome and there are others as well. For this discussion board, address the following components:

1)    Describe the effect of a nondisjunction event in the first division and one in the second in your own words.

2)    Choose a syndrome that  results from nondisjunction.

3)    For the syndrome: Describe the specific anomaly, the affects that are known, any factors that may increase the occurrence of this abnormality, and the percent of the population that demonstrate this chromosome number abnormality

Take a position on whether or not standardization and naming conventions are critical for properly managing files and folders in a Windows environment. Include at least one (1) example or scenario to support your response.

• Read the article titled “The Windows XP upgrade question: Windows 7 or Windows 8?”You can also use the Internet or Strayer Library to research articles on features about Windows 7 and Windows 8. Next, compare and contrast at least one (1) feature that differs from Windows 7 and Windows 8.1. Then, select one (1) feature that you believe has been improved in Windows 8.1 and one (1) feature that you believe has worsened in Windows 8.1. Justify your response.

In this assignment, take a few minutes to contemplate the world of business as you see it today, especially in light of the technologies that are evolving around us. Think, too, about the future of technology and how it could affect business.

Using PowerPoint, create a 3-5 slide presentation that demonstrates how the use of technology figures into how you personally conduct business. Include how you think you will conduct business in the future.

Requirements

1. Assume you are sharing your personal viewpoints in a somewhat formal setting, like a classroom, where you are presenting to classmates.
2. The presentation must include at least three slides, but no more than five.
3. The first slide must include your name and the topic.
4. You must apply a design theme.
5. You must use slide transitions on all slides.
6. You must include at least two pictures or clip art.
7. Use the slides to only highlight key points, but include the entire speech in the Speakers Notes for each slide you are presenting. Yes, you must write a speech, but please keep the tone comfortable and casual – remember that you are simply sharing your views and impressions.
8. Be sure to check grammar and spelling. Even a rather informal presentation must be delivered professionally.
