The Stock class: Design a class named Stock that contains:
• A string data field named symbol1 for the stock’s symbol.
• A string data field named name for the stock’s name.
• A double data field named previousClosingPrice that stores the stock price for the previous day.
• A double data field named currentPrice that stores the stock price for the current time.
• A constructor that creates a stock with the specified symbol and name.
• A method named getChangePercent() that returns the percentage changed from previousClosingPrice to currentPrice.
• Write a test program that creates a Stock object with the stock symbol ORCL, the name Oracle Corporation, and the previous closing price of 34.5. Set a new current price to 34.35 and display the price-change percentage.

Using java you have to create a simple program that will allow for the storage of requests for money. Each request will consist of a person's name and dollar amount (US dollars). The business rules are straight forward. Each name should be a first and last name. The first letter of each element in the name should be capitalized. The dollar amount should be between 1 and 1000 dollars and include cents (2 decimals). You should include validations, but it will be left to you to decide if they will methods in the data entry program, or methods from a validation class. The data entered for each request should be written to an encrypted file. Use combo boxes and "good lists" where appropriate. Throw exception objects to handle errors and fail securely.

Three employees in a company are selected for a pay increase. You are given a file (salaries.txt) that contains three lines. Each line in the file consists of an employee’s last name, first name, current salary, and percent pay increase. For example, in the first line, the last name of the employee is Miller, the first name is Andrew, the current salary is 65789.87 and the pay increase is 5%. Write a program that reads data from the file and stores the output in another file. The output data must be in the following format: FirstNameInitial lastName updatedSalary Format the output of decimal number to two decimal places. For example, the first line in the output may look like the following: A. Miller 69079.36 I want help to solve it on netbeans

Consider the following java class:

class Student {
   private int student_Number;
   private String student_Name;
   public Student(int stNo,String name) {
        student_Number=stNo;
        student_Name=name;
     }
    public String getName() {
      return student_Name;
    }
     public int getNumber() {
      return student_Number;
     }
    public void setName(String st_name) {
      student_Name = st_name;
    }
}

Write a Tester class named StudentTester which contains the following instruction:

1. Use the contractor to create a student object where student_Number =12567, student_Name = “Ali”.
2. Use the setName method to change the name of the student to “Ahmad”
3. Print the student details(i.e., student’s name and student’s number).

Note:

Include the screenshot of the program output as a part of your answer. Otherwise, you will be marked zero for this question.

Write program#1 upload .java file. #1 Write a java program that prompts the user for input using the Scanner class. First to enter their first name. Then prompts the user to enter their last name. Then prompts the user to enter their city. Then prompts the user to enter their state. Then prompts the user to enter their zip code. Concatenate first name and last name into full_name. Using String Class is optional. Use the String Class to replace zip code "0" with "N", replace "7" with "J". Use the String Class to make all the values upper case. Use the String Class to determine the length of full_name. Print on first line full_name and length of full_name. Print all on second line mailing address, including zip_string?

(1) Create three files to submit.

• ContactNode.h - Class declaration

How do you write this code?

code in C

Step 1

• Write a program that will read in a list of addresses (100 maximum) from a file.
• The program should read records from a file until an EOF is found.
• The program must read one character at a time from the file using fgetc.

For example: chrLetter = fgetc( pfilInput );

• No partial addresses/records will be given.
• The format of the addresses is: RecordID, Full Name, Street, City, State, ZipCode

Step 2

• Store the addresses in an array of structures.
• Use the typedef below
• You will have to parse the input lines to separate the fields.
• You will have to separate full name into first, middle and last name.
• Trim all leading and trailing whitespace for EACH field.

typedef struct

{

      long lngRecordID;

      char strFirstName[ 50 ];

      char strMiddleName[ 50 ];

      char strLastName[ 50 ];

      char strStreet[ 100 ];

      char strCity[ 50 ];

      char strState[ 50 ];

      char strZipCode[ 50 ];

} udtAddressType;

Step 3

• Call a subroutine from main and pass the array of structures as a parameter. In the subroutine, load all the addresses from the file into the array of structures.

Step 4

• Call a subroutine from main and pass the array of structures as a parameter. In the subroutine, print out all the addresses. Make it look pretty. Don’t print out blank records. For example:

------------------------------------------------------------

Customer #1

            First Name:          Luke

            Middle Name:      

            Last Name:          Skywalker

            Address:              123 Elm Street

            City:                    Corusant

            State:                  Ohio

            Zip Code:             45202

------------------------------------------------------------

Customer #2

…

Extra Credit

• After you read in the addresses call a subroutine to sort the addresses alphabetically by last name, first name. Try the quick sort in the STL (standard template library).

Extra Extra Credit

• Eliminate any duplicates addresses (just check street and zip code).

To meet rising demands for health care, a new form of clinics has begun to emerge: clinics run by nurse practitioners says the New York Times.

• About 250 health clinics across America are now completely run by nurse practitioners.
• These nurses require a master's degree that includes two or three years of advanced training in treating and diagnosing diseases.
• A new proposal endorsed by the American Association of Colleges of Nursing for 2015 would require nurse practitioners to have a doctorate of nursing practice.

Many of these nurse practitioners are limited in what they can and can't do based on state law. In some states, nurse practitioners are completely free to treat patients and give prescriptions. However, some states won't allow these clinics without at least one trained physician.

These clinics staffed with nurse practitioners offer an avenue for alleviating some of the strain being put on primary care physicians. Indeed, the Affordable Care Act will bring 32 million uninsured people into the health system and there aren't enough primary care physicians to cover them. Furthermore, physicians are poorly distributed, many of them opting to work in urban areas rather than rural towns.

Some critics of having nurse practitioners run clinics argue that the quality of care is compromised for patients.

• However, data has shown nurse practitioners provide good quality care.
• One-hundred and eighteen published studies over 18 years found that nurse practitioner-led clinics were at the least equivalent, if not better, when compared to doctor-led clinics.

Moreover, nurse-led clinics are cheaper than traditional doctor-led practices. Furthermore, these clinics are small and don't need a variety of practitioners to keep the clinic at full capacity. Finally, nurse practitioner-led clinics provide patients with an alternative to the emergency room, which results in large savings.

a. The government of Ghana has gradually outlined measures to ease an opening of the economy. The government is eager to see the economy bounce back. Suppose the government approaches you as a consultant and indicates that they will like to have a very low unemployment, zero inflation and very high GDP growth. How would you advice the government? Be concise in your advice. [10 Marks]

b. Business cycles are pervasive in all macroeconomic variables. Does the relative durations of expansions and recessions help explain the fact that long-term economic growth has been positive?
