Chapter 10, Problem 2E
Open the Palace Solution.sln file contained in the VB2017\Chap10\Palace Solution folder.
- a. Use Windows to copy the Rectangle.vb file from the VB2017\Chap10 folder to the Palace Project folder. Then, use the Add Existing Item option on the Project menu to add the file to the project.
- b. Modify the Rectangle class to use Double variables rather than Integer variables.
- c. Change the name of the GetArea method to GetAreaSqFt.
- d. Add another method to the class. Use Get AreaSqYds as the method’s name. The method should calculate and return the area of a rectangle in square yards.
- e. The application’s Calculate button should calculate and display the number of square yards of carpeting needed to carpet a rectangular floor. Code the btnCalc_Click procedure. Display the number of yards with one decimal place. Save the solution and then start and test the application.

Then create a new Java application called "Rooter" (without the quotation marks) to get a positive integer (i.e. any number greater than 0) called "start" from the user at the command line and then find the square root of every number from "start" down through 0. Use a while loop to count down. As an example, if the user entered 8, you would find the square root of 8, then the square root of 7, and so on. Print each square root on a separate line. Include data validation to ensure the user provides a positive integer. If the validation is not passed, provide the user with suitable feedback and stay in the program to let the user try again until valid input is received.

The concept of application is as follows: The program will read numbers from a file - data.txt - that you will create, where the weight is a double (greater than 0.0 and less than or equal to 1.0) and the other numbers are the number, n, of lowest values to drop and then the numbers to be averaged after dropping the lowest n values.

- You will be writing a scheduling application allowing a convention center to schedule events. This program will contain two different classes: Date and Event. Both classes should be defined on their own .py modules. You may use the Date class we designed in class in lecture 18 (which will also be posted on Canvas). The Event class should have the following attributes: event_date (which should be a Date object) event_name start_hour: Uses a 24-hour clock, so should be a value between 0 and 23 endHour: Uses a 24-hour clock, so should be a value between 0 and 23 The Event class should have the following methods: __str__. Return a string representation of all important info about this Event: The name of the event, the start and end times (you can simply print their value i.e. from 14 to 16) and the Date. Properties and setters for the attributes. A constructor which takes a name, start and end hours, and a Date object.

Create a folder named LastName_FirstName (ex. Reyes_Mark) in your local drive. 2. Create a new project named LabExer6A. Set the project location to your own folder. 3. Create a simple guessing game (similar to Hangman or Hangaroo). In this game, the user guesses a letter and then attempts to guess the word. 4. Create a Notepad file named words.txt which will store any number of words each written per line. 5. The Java program shall: • randomly select a word from the list saved in words.txt; • display a letter in which some of the letters are replaced by ?; for example, ED??A??ON (for EDUCATION); place the letter in the correct spot (or spots) in the word each time the user guesses a letter correctly; • inform the user if the guessed letter is not in the word; and display a congratulatory message when the entire correct word has been deduced.arrow_forward
