Question 1 (Employee): Base Class Information                                                          10 Points

1. Create a class called Employee that should include four pieces of information as instance variables—a firstName (type String), a lastName (type String), a mobileNumber (type String) and a salary (type int).
2. Your class (Employee) should have a full argument constructor that initializes the four instance variables.
3. Provide a set and a get method for each instance variable. The validation for each attribute should be like below:
   1. mobileNumber should be started from “05” and the length will be limited to 10 digits.
   2. salary should be greater than zero.
4. In addition, provide a method named getYearlySalary() that calculates the yearly salary (i.e., multiplies the salary by 12), then returns the amount as a double value.
5. The toString() print the following information

Employee Name: FirstName LastName

Mobile No. 0512345678

Employee Salary: 2000

convert -44 to 8-bit sign-magnitude, 1's complement, 2's complement and excess-127.

Please be careful and explain all the steps and details.

Python Code

Assignment

1. Place the two provided plaintext files (file_1.txt, file_2.txt) on your desktop.

2. Write a Python program named fun_with_files.py. Save this file to your desktop as well.

3. Have your program write the Current Working Directory to the screen.

4. Have your program open file_1.txt and file_2.txt, read their contents and write their contents into a third file that you will name final.txt .

Note: Ponder the open‐read/write‐close file operation sequence carefully.

5. Ensure your final.txt contains the complete text of file_1.txt followed by the complete text of   file_2.txt.  

Write a program named "cleanDocument.pl" that will do the following:

• Reads two parameters from the command line (@ARGV)
  • The first parameter is the name of a file and the second parameter is a word
  • If no command line parameters are present, it asks the user to input the values
• Opens the text file that is passed as the first command line argument
• Loops through the lines of the text file and replaces all occurrence of the word (the second command line parameter) with an equal number of dashes (that is the same amount of dashes as the word length)
• It then overwrites the file with the new replaced data

Below is an example of how the program works:

Calling the Perl file on the command line like so:

$ cleanDocument.pl document.txt bobsled

or

$ cleanDocument.pl
$ What file do you want to open? document.txt
$ What word do you want to replace? bobsled

If the file looks like below:

$ cat document.txt

I like to use my bobsled during the winter. Whenever I bobsled I have a lot of fun.

Then it will be become:

$ cat document.txt

I like to use my ------- during the winter. Whenever I ------- I have a lot of fun.

You prepare a schedule of your physical exercises for the next fortnight (14 days). You don’t do physical exercise more than once a day. If you have 10 PE sessions planned, explain using the counting principles covered in class how this means you will do PE on consecutive days at least once in the next fortnight.

how do you create a list in python to calculate BMI, if you were to want variables like height, weight, BMI, and classification in the list

Write a VB program to provide a health analysis. The higher the point total, the less healthy you are. Input will consist of the user's name, age group, smoker status, weight, sex, blood pressure, and cholesterol readings.

Risk Points are assigned as follows:

Age Group

18 or below0 points

19 - 301 point

31 - 602 points

over 604 points

Smoker?

Yes 5 points

No 0 points

Systolic Blood Pressure?

60 - 139 (Normal) 0 points

140 - 159 (Borderline) 2 points

over 159 (High) 4 points

Diastolic Blood Pressure?

40 - 89 (Normal) 0 points

90 - 94 (Borderline) 2 points

over 94 (High) 4 points

LDL (Bad) Cholesterol

< 110 0 points

110 and up 2 points

HDL (Good) Cholesterol

> 1/5 of Total Cholesterol 0 points

≤ 1/5 of Total Cholesterol 2 points

Weight

Female, over 200 lbs 3 points

Female, 150 - 200 lbs 2 points

Female, < 150 lbs 0 points

Male, over 260 lbs 3 points

Male, 200 - 260 lbs 2 points

Male, < 200 lbs 0 points

A sample user-interface design is attached for your use. Note that the user's name, and cholesterol readings are to be entered into textboxes. The sex and smoking status are entered via radio buttons. The weight and blood pressure (systolic and diastolic) are entered via Numeric UpDown controls. The age group is chosen from a combo box control.

The primary button on your form (Analyze Data) will contain all the code to solve this problem in its Click event procedure. You should also make this event procedure executable by simply pressing the ENTER key when the program runs.

Two other buttons...Quit (to pop up a "Farewell Greeting" message box to the user and stop program execution), and a Clear button (to reset all controls back to original values, and move the cursor back to the "Name" textbox), should also have their click event procedures coded.

Finally, a listbox should be included on your form to output the user's results as follows.

Note:

Total Cholesterol is LDL Cholesterol plus HDL Cholesterol.

Health Status is determined as follows:

Total Points Status

0 - 9Good

10 - 18Average

19 - 24Poor

Programming Notes

1. All code to solve this problem will be written in the "Analyze Data" Click event procedure. Therefore, all variables (meaningful, and properly data-typed) will be declared locally to this event procedure. No global (form-level) variables should be used.

2. The following variables and corresponding data types are suggested (You can add prefixes as needed).

Variable Data Type

namestring

weightinteger

HDLinteger

LDLinteger

TotalCholesterolinteger

SystolicBPinteger

DiastolicBPinteger

SmokePointsinteger

WtPointsinteger

AgePointsinteger

LDL Pointsinteger

HDL Pointsinteger

SystolicPointsinteger

DiastolicPointsinteger

TotalPointsinteger

HealthStatusstring

3. Code OPTION STRICT ON at class level to ensure all variables are properly declared in your program.

4. Use IF statements (single, dual, or multiple alternative, as needed) to determine points from Smoking, Systolic blood pressure, Diastolic blood pressure, HDL Cholesterol, LDL Cholesterol, and weight.

For example, suppose you want to assign points for user's smoking status. You would code the following:

Dim SmokePoints As Integer

If radSmokeYes.Checked = True Then

SmokePoints = 5

Else

SmokePoints = 0

End If

5. Use a Select/Case statement to determine points from the age group of the user.

6. Although you set the min/max for 40/300 for Systolic nud (in the Initial Properties Window), use data validation to ensure that user enters an integer between 60 and 200 inclusive into the Systolic Blood Pressure numeric updown control. If not, display an appropriate error message (via titled, descriptive message box), set insertion point back to Systolic Blood Pressure numeric updown control to allow the user to try again and Exit Sub to prevent further execution without having all the "input data.".

7. Do the same as in Step 6 above but set the min/max for 20/200 for Diastolic nud, for the Diastolic Blood Pressure reading, ensuring the user enters an integer between 40 and 120 inclusive.

I just need help with the coding of the project. Any help would be appreciated :)

Create an executable bash script named sync. You may find file name pattern matching and the basename command useful. In fact, the sync-skeleton file contains part of the solution to this problem. You may choose to use it anyway you wish. You'll have to create your own test directories (using the mkdir command) and files (using the touch command) to test this script.

You should research the options to the cp command in its main page.

1. The script takes TWO ARGUMENTS. Let's call them dir1 and dir2. If two arguments are not given display an error message to that effect and exit.

2. Verify that both given arguments are paths to directories. If one or neither argument is a path to a directory, display an error message to that effect and exit.

3. If a file exists in dir1 but not in dir2, copy the file from dir1 to dir2 preserving its timestamp. Display a message saying what's being done.

4. If a file exists in dir2 but not in dir1, copy the file from dir2 to dir1 preserving its timestamp. Display a message saying what's being done.

5. If a file is in both directories but is newer in dir1 than the file in dir2, copy the file from dir1 to dir2 preserving its timestamp. Display a message saying what's being done.

6. If a file is in both directories but is newer in dir2 than the file in dir1, copy the file from dir2 to dir1 preserving its timestamp. Display a message saying what's being done.

PYTHON PROBLEM:

Goal: Design and implement a Python program to solve the following problem.

Scientists measure an object’s mass in kilograms and weight in newtons. If you know the amount of mass of an object in kilograms, you can calculate its weight in newtons with the following

formula:

[Note: Use or test any random numbers to check whether the weight is heavy, can be lifted or light]

????h? = ???? × 9.8

Write a program that asks the user to enter an object’s mass in kilograms, then calculates its weight in newtons. If the object weighs more than 980 newtons, the program should display the following message

The object is too heavy to be lifted

obviously indicating that it is too heavy to be lifted; otherwise, it should display the message

The object can be lifted

with the obvious meaning. If the object weighs less than 98 newtons, the program must display the following additional message

The object is quite light

1. Write the pseudocode for solving the problem.

2. Write the Python program.

Suppose there is only one customer service available in SAMBA Bank in Thursday morning, in every 4 minutes a new customer arrives at the end of waiting line, each customer will need 7 minutes for the service

Write a program to print out the information after the first 60 minutes

• The time of arriving for each customer
• The time of leaving for each customer
• How many customers are in the line?
• Who is the current serving customer?

(((( data structure course

Programming Language: java
Hint: use the queue concept )))

This is to be done using MIPS assembly language.

Display the following menus, ask user to select one item. If 1-3 is selected, display message “item x is selected”, (x is the number of a menu item), display menus again; if 0 is selected, quit from the program.

1. Menu item 1

2. Menu item 2

3. Menu item 3

0. Quit Please select from above menu (1-3) to execute one function. Select 0 to quit

create a java class with name ModernArt:

For the first part of the assignment, you will be extending the JApplet class and creating a work of modern using the Graphics class to draw various shapes to the applet window. As part of your masterpiece, you should incorporate the following elements:

• At least 1 non-solid rectangle
• At least 1 non-solid oval
• At least 1 solid oval
• At least 1 non-solid Polygon
• At least 1 solid Polygon
• At least 3 lines
• At least 3 different colors
• A caption (a text String) displayed somewhere on your work of art

You may use more elements than the minimal requirements above, but you must use at least that many. There are unit tests for this question that will determine if you have correctly included the required shapes and colors, but there are no tests to judge your work itself as it is not possible to write unit tests which measure the sheer lack of sophistication typically embodied by so much of modern art.

a. Person is an abstract class.

b. All class variables of the Person class must be private.

c.is a class with a single constructor, Person(String lName, String fName, int birthYear, int birthMonth, int birthDay). All arguments of the constructor should be stored as class variables. There should only be getter methods for first and last name variables. There should be no getters or setters forbirthYear, birthMonth, birthDay.

4. The method computeAge() takes no arguments and returns the person’s computed age (as of today's date) as a string of the form "X years, Y months and Z days". Hint: Use the LocalDate and Period classes.

   i. e.g. "21 years, 2 months and 3 days". ii. e.g. "21 years and 3 days".

   iii. e.g. "21 years and 2 months". iv. e.g. "21 years".

   v. e.g. "2 months and 3 days".
