Background: introduction to "Wrapper" classes, this is a tool or concept provided in the Java Programming Language that gives us a way to utilize native datatypes as Objects with attributes and methods. A Wrapper class in Java is the type of class which contains or the primitive data types. When a wrapper class is created a new field is created and in that field, we store the primitive data types. It also provides the mechanism to covert primitive into object and object into primitive.Working with collections, we use generally generic ArrayList<Integer> instead of this ArrayList<int>. An integer is wrapper class of int primitive type. We use a Java wrapper class because for generics we need objects, not the primitives."

Problem: Create a Word Counter application, submit WordCounter.java.

Word Counter takes input of a text file name (have a sample file in the same directory as your Word Counter application to we don't have to fully path the file). The output of our Word Counter application is to echo the file name and the number of words contained within the file.

Sample File: Hello.txt:

hello

hello

hello

hello

hello

hello

hello

hello

hello

hello

Using this code snippet: Answer the following questions

<div id=”mainContent”>

     <p>I’m a cool paragraph

<span>

    that has some

                  <span class=”coolClass”>yellow</span>

                  text

            </span>

     </p>

     <p class=”blue”>

            I’m just some blue text

      </p>

      <p class=”coolClass”> I should be un-touched text </p>

</div>

<div id=”footer”>

     <p class=”tagLine”>Copyright &copy; 2014</p>

</div>

1. Write the CSS rule (selector/declaration) to change all elements with a class of ‘blue’ to have blue foreground text. Hint: color

2. Write the CSS rule to change just the span with a class of “coolClass” to have a text color of yellow.

3. Write the CSS rule to change the element with and id of ‘footer’ to have a font size of 12px. Hint: font-size

4. Write the CSS needed to make all paragraphs in the document have a font weight of bold. Hint: font-weight

Below are the parallel arrays that track a different attribute of the apples (note that the above chart (Sweet-Tart Chart) doesn't align with the data from the previous lesson):

names = ["McIntosh", "Red Delicious", "Fuji", "Gala", "Ambrosia", "Honeycrisp", "Granny Smith"]

sweetness = [3, 5, 8, 6, 7, 7.5, 1]

tartness = [7, 1, 3, 1, 1, 8, 10]

Step 1: Data Model (parallel arrays to dictionary)

Build a dictionary named apples. The apple dictionary keys will be the names of the apples. The values will be another dictionary. This value dictionary will have two keys: "sweetness" and "tartness". The values for those keys will be the respective values from the sweetness and tartness lists given above. You will build this by defining a variable named apples (see the complex_map example).

This is why dicitionarries are also calleed associative arrays. The arrays need to be kept in order so they can associate the same index with the same corrresoponding value that make holding this kind of data easier.

Step 2: Apple Aid

Now that we have our model, create a function named by_sweetness whose parameter will be a tuple (from apples.items()) The function by_sweetness will return the sweetness value of the incoming tuple. This helper function cannot reference the global variable apples (from step 1).

Create another function by_tartness that is essentially the same as by_sweetness but returns the tartness value of the incoming tuple.

Step 3: Apple Sorting

Write a function called apple_sorting that has two parameters: data (the data model dictionary) and sort_helper (the function used to sort the model). The apple_sorting should use the sorted function to sort the data (e.g. data.items()) with sort_helper. The function returns a list of tuples in order of their sweetness (sweetest apples listed first).

Once done, this should work:

print(apple_sorting(apples, by_sweetness))

Provide brief definitions and an example for each of the following.

a. acute care

b. ALOS

c. Chronic disease

d. Data Mart

e. BI

Regarding clinician use of the EMR/EHR, when is the best time to access and document into the EMR/EHR? Explain.

There are three steps (open, action, close) required for handling files. You need to write a Python program what executes each of these three steps. Your program must include:
 Extensive comments to ensure explanation of your code (1).
 Open a file (file name must include your student number, thus filexxxxxxxx.txt). (1).
 Write the details of the five students (from Question 1 above) to a file (3).
 Close the file. (1)
 Then open the file again (1).
 Write the contents of the file to display on the screen (3).

Taking as a reference a sensor that delivers a reading through a parallel bus at a rate of 12 bits/ms, carry out a program within MARIE's environment that stores the first 50 measurements in memory.

UseMath

Write a program called UseMath. It should contain a class called UseMath that contains the method main.

The five key activities in an object-oriented design process are:

a. Define the context and modes of use of the system;
b. Design the system architecture;
c. Identify the principal system objects;
d. Develop design models;
e. Specify object interfaces.

Please give me an explanation and example in detail for the five activities.

Below are a list of sequences of numbers. Your job is to program each sequence with any loop of your preference (while, for, do/while). I want the code to output the sequence provided and the next number in the sequence (you can output more but there is 1 sequence that may only have 1 number after).. Please order and notate each sequence in your output –. The output should also be horizontal like that shown below (if you output it vertically it will be -10pts). Each sequence should be programed with only 1 loop and optionally 1 selection statement. Hint: a selection statement may be used for the last 3 problems.

Problem 1
        The United States Federal Income tax for taxes due July 15, 2020
    is available at this link: https://www.bankrate.com/finance/taxes/tax-brackets.aspx
        The four tax filing categories are: 0 - single filer, 2 - head of household, 
        3 - married filing jointly or qualifying widow, and 4 - married filing
        seperately. 
        
        Write a Java program that prompts the user to enter the name, filing status, and
        annual income. The program returns the federal income tax due. (10 Points)
        
        A sample run should look like:
        Enter your name: Jane Doe
        Enter your 2019 federal income: 48,000
        Enter your filing status: single
        
        Jane Doe, the federal income tax for an annual salary of
        48,000 for a single filer is $4,800.
        
        
        Draw a UML diagram for the class. You may use Astah tool. (5 points).

This is a beginner C++ class

Your program will be creating 10 library books. Each library book will have a title, author and publishing year. Each library book will be stored as a structure and your program will have an array of library books (an array of structures).

After creating the struct, the next task is to create a new separate array for book genres.

You will create this corresponding array of book genres: Mystery, Romance, Fantasy, Technology, Children, etc. If the first element of the structure is storing information about a book titled : "More about Paddington", then the corresponding first element of array book genre would indicate 'Children'.

You should only use structure and array. You are not allowed to use vectors.

The user of your program should be able to select what they want to do from a menu of the following things and your program needs to do what the menu selection indicates:

* Print the entire list of library books (including the title, author, publishing year and book genre)

* Display a count of how many books exist per genre

* Find and display all books where the publishing year is greater than the year user put in

* Print the titles of the books where the Genre may be indicated by a 'C' for Children, & 'M' for Mystery
