Coding in Java Assignment

1. Write the following static methods. Assume they are all in the same class. Assume the reference variable input for the Scanner class and any class-level variables mentioned are already declared. All other variables will have to be declared as local unless they are parameter variables. Use printf.

1. A method that prompts for the customer’s name and returns it from the keyboard.

2. A method called shippingInvoice() that prompts for an invoice number and stores it in a class variable (field) called invoiceNo. Assume the invoice number is a combination of numbers and text.

3. Overload the method coded in 1b above so that it accepts a customer’s name through its parameter list, concatenates the name and invoice number in a header and returns the header. This method will not prompt for the name or invoice number. The content of the header will look like this where the Xs represent the actual customer name and invoice number:

Customer Name: Xxxxxxxxxxxx

Invoice No: XXXXXXXX

4. A method that prompts for the subtotal and returns it from the keyboar

5. A method that prompts for the number of items purchased and returns it from the keyboard.

6. A method that accepts the noItemsPurchased and the subtotal through its parameter list and returns an average dollar amount of the items purchased. No prompts are needed.

7. A method that accepts what is returned by the methods coded in 1c and 1f to print the following:

Customer Name: Xxxxxxxxxxxx

Invoice No: XXXXXXXX

Average of Items Purchased: $ZZZ,ZZ9.99

2. Write statements that will call each of the methods you coded above. Be conscious of the value-returning methods. Assume the method calls are done in the main() and the main() is in the same class.

1. Return the full names (first and last) of actors with “SON” in their last name, ordered by their first name.
2. Find all the addresses where the second address (i.e. address2) is not empty (i.e., contains some text), and return these second addresses sorted.
3. Your Professor wants you to find all the information from rental table associated with those staff (or staff ID) whose address ID is 4 (in staff table). Professor wants you to use Sub-query function.
4. Your Professor wants you to find out the first name and district of all the customers whose district ends on “ia” – such as California.
5. Your Professor wants you to find all the payment-related information of customers other than the customer whose ID is 1.
6. Your Professor wants you to find out the full name (i.e. combine the first and last name) and the district of all the customers that live in a district called California.
7. Your Professor wants you to find the title, film id and category name (such as action) of those movies that are of the action genre (i.e. category name is Action).
8. Return the first and last names of actors who played in a film involving a “Crocodile” and a “Shark”, along with the release year of the movie, sorted by the actors’ last names.
9. Find all the film categories in which there are between 55 and 65 films. Return the names of these categories and the number of films per category, sorted by the number of films.
10. In how many film categories is the average difference between the film replacement cost and the rental rate larger than 17?

Lesson is on Inheritance and overriding the ToString ( ) method in Java:

The program should consist of 3 classes and will calculate an hourly paycheck.

   - The superclass will contain fields for common user data for an employee (first name and last name) and a toString method that returns the formatted output of the names to the calling method.

   - The subclass will calculate a paycheck for an hourly employee and will inherit from the superclass.

   - The testclass will interface with the user.

   - The superclass will be used to set the first and last name of the employee.

   - The subclass should have additional instance variables for the hours worked, the hourly rate of pay and the weekly pay that they calculate.

   - The subclass should have a toString method that prints the calculated weekly paycheck from the class plus calls the toString method of the superclass to obtain the formatted first and last name.

   - Create a basic driver class to supply input from the user into the program and print the results. (The results must be correct.)

Here is the grading rubric:

Create a superclass that sets the first name and last name as private instance variables and has a toString method that returns a formatted string of the employee’s first and last name

Create a subclass that inherits the superclass, calculates a weekly paycheck for an hourly employee and contains a toString method that calls the superclass toString method plus adds the weekly paycheck amount to the formatted output supplied by the superclass

The subclass contains a constructor that calls the super class constructor

The subclass overrides the toString method in the superclass and adds the weekly paycheck amount to the string it returns

The test class code should create object, call methods to calculate the weekly paycheck and print the results

Python - Rewriting a Program

Rewrite Program 1 using functions. The required functions are in the table below.

Create a Python program that will calculate the user’s net pay based on the tax bracket he/she is in. Your program will prompt the user for their first name, last name, their monthly gross pay, and the number of dependents.

The number of dependents will determine which tax bracket the user ends up in. The tax bracket is as follows:

• 0 – 1    Dependents:    Tax = 20%
• 2 – 3    Dependents:    Tax = 15%
• 4+        Dependents:    Tax = 10%

After calculating the net pay, print the name of the user, the monthly gross pay, the number of dependents, the gross pay, the tax rate, and the net pay.

The formula to compute the net pay is: monthly gross pay – (monthly pay * tax rate)

Sample run:

Enter your name: Ron Swanson
Enter your gross pay: $3500
Enter number of dependents: 0

Name:      Ron Swanson
Gross pay: $3500.00
Dependents: 0
Tax rate: 20%
Net Pay: $2800.00

(c++)You will be given a data file containing data for 10 students. The format is as follows - grades are double precision numbers:

Line 1: Header Information

Line 2: Student Full name

Line 3: Student ID

Line 4: testgrade_1 testgrade_2 testgrade_3 testgrade_4 testgrade_5

Line 5: Student Full name

Line 6: Student ID

Line 7: testgrade_1 testgrade_2 testgrade_3 testgrade_4 testgrade_5

Line 8: Student Full name

Line 9: Student ID

Line 10: testgrade_1 testgrade_2 testgrade_3 testgrade_4 testgrade_5

Etc.

1. Read the data into appropriate arrays. You do not need to create a dynamic array.

2. Determine the average of all the grades for each test, and print the test number then the name, student id, and grade for all students who fall below that average.

3. Determine the average of all the grades for each student.

4. Determine which student has the highest average grades - print their name and their average

5. Determine which student has the lowest average grades - print their name and their average

Problem 11-10

Martinez Corporation, a manufacturer of steel products, began operations on October 1, 2016. The accounting department of Martinez has started the fixed-asset and depreciation schedule presented below. You have been asked to assist in completing this schedule. In addition to ascertaining that the data already on the schedule are correct, you have obtained the following information from the company’s records and personnel.

Complete the schedule below. (Round answers to 0 decimal places, e.g. 45,892.)

1. Assume that the company was operating at full capacity in 2016 with regard to all items except fixed assets; fixed assets in 2016 were being utilized to only 64% of capacity. By what percentage could 2017 sales increase over 2016 sales without the need for an increase in fixed assets? Round your answer to two decimal places.
   %
2. 
   
3. Now suppose 2017 sales increase by 25% over 2016 sales. Assume that Krogh cannot sell any fixed assets. All assets other than fixed assets will grow at the same rate as sales; however, after reviewing industry averages, the firm would like to reduce its operating costs/sales ratio to 80% and increase its total liabilities-to-assets ratio to 42%. The firm will maintain its 60% dividend payout ratio, and it currently has 1 million shares outstanding. The firm plans to raise 35% of its 2017 forecasted interest-bearing debt as notes payable, and it will issue bonds for the remainder. The firm forecasts that its before-tax cost of debt (which includes both short- and long-term debt) is 10.5%. Any stock issuances or repurchases will be made at the firm's current stock price of $40. Develop Krogh's projected financial statements. What are the balances of notes payable, bonds, common stock, and retained earnings? Round your answers to the nearest hundredth of thousand of dollars.
