Chapter 4: Making Decis ions I. Mass and VWeight (Nr 2, Page 282) Scientists measure an object's mass in kilograms and its weight in Newton. If you know the amount of mass of an object, you can calculate its weight, in Newtons, with the following formula: Weight = Mass x 9.8 Create an application that lets the user enter an object's mass and then calculates its weight. If the object weighs more than 1000 Newtons, display a message in a Label control indicating that it is too heavy and change the background colour of the label to red. If the object weighs less than 10 Newtons, display a message in a Label control indicating that it is too light and change the background colour of the label to blue. Otherwise display the weight, and change the background colour of the label to green. See example of graphical user interface and output: Newton converter Newton converter Enter the mass (kg) : Enter the mass kg): 1 Convert to mass (Newton) Convert to mass (Newton) It is too light.

Carpet Calculator The Westfield Carpet Company has asked you to write an application that calculates the price of carpeting for rectangular rooms. To calculate the price, you multiply the area of the floor (width times length) by the price per square foot of carpet. For example, the area of floor that is 12 feet long and 10 feet wide is 120 square feet. To cover that floor with carpet that costs $8 per square foot would cost $960. First, you should create a class named RoomDimension that has two fields: one for the length of the room and one for the width. The RoomDimension class should have a method that returns the area of the room. (The area of the room is the room’s length multiplied by the room’s width.) Next you should create a RoomCarpet class that has a RoomDimension object as a field. It should also have a field for the cost of the carpet per square foot. The RoomCarpet class should have a method that returns the total cost of the carpet. Figure 8-20 is a UML…

Fat Percentage Calculator One gram of fat has 9 calories. If you know the number of fat grams in a particular food, you can use the following formula to calculate the number of calories that come from fat in that food: Calories from fat = Fat grams × 9 If you know the food’s total calories, you can use the following formula to calculate the percentage of calories from fat: Percentage of calories from fat = Calories from fat ÷ Total calories Create an application that allows the user to enter: • The total number of calories for a food item • The number of fat grams in that food item The application should calculate and display: • The number of calories from fat • The percentage of calories that come from fat Also, the application’s form should have a CheckBox that the user can check if he or she wants to know whether the food is considered low fat. (If the calories from fat are less than 30% of the total calories of the food, the food is considered low fat.) Use the following test data…
99 question Reza Enterprises sells tickets for buses, tours, and other travel services. Because Reza frequently mistypes long ticket numbers, Reza Enterprises has asked his students to write an application that shows if a ticket is invalid. Your application/program tells the ticket agent to enter a six-digit ticket number. Ticket numbers are designed so that if you lose the last digit of the number, then divide by 7, the remainder of the division is exactly the same to the last dropped digit. This process is shown below: Step 1: Enter the ticket number; for example 123454 Step 2: Remove the last digit, leaving 12345 Step 3: Determine the remainder when the ticket number from step 2 is divided by 7. In this case, 12345 divided by 7 leaves a remainder of 4. Step 4: Display a message to the ticket agent indicating whether the ticket number is valid or not. If the ticket number is valid, save the number to a .txt file called “tickets.txt” and.
Driver’s License Exam The local driver’s license office has asked you to create an application that grades the written portion of the driver’s license exam. The exam has 20 multiple-choice questions. Here are the correct answers: 1. B 2. D 3. A 4. A 5. C 6. A 7. B 8. A 9. C 10. D 11. B 12. C 13. D 14. A 15. D 16. C 17. C 18. B 19. D 20. A Your program should store these correct answers in an array. The program should read the student’s answers for each of the 20 questions from a text file and store the answers in another array. (Create your own text file to test the application.) After the student’s answers have been read from the file, the program should display a message indicating whether the student passed or failed the exam. (A student must correctly answer 15 of the 20 questions to pass the exam.) It should then display the total number of correctly answered questions, the total number of incorrectly answered questions, and a list showing the question numbers of the incorrectly…
Magic Dates The date June 10, 1960, is special because when it is written in the following format, the month times the day equals the year: 6/10/60 Create an application that lets the user enter a month (in numeric form), a day, and a two-digit year. The program should then determine whether the month times the day equals the year. If so, it should display a message saying the date is magic. Otherwise, it should display a message saying the date is not magic.
Kinetic Energy In physics, an object that is in motion is said to have kinetic energy. The following formula can be used to determine a moving object’s kinetic energy: KE =1/2mv2 In the formula KE is the kinetic energy, m is the object’s mass in kilograms, and v is the object’s velocity in meters per second. Create an application that allows the user to enter an object’s mass and velocity and then displays the object’s kinetic energy. The application should have a method named KineticEnergy that accepts an object’s mass (in kilograms) and velocity (in meters per second) as arguments. The method should return the amount of kinetic energy that the object has.

Salesperson's Commission Calculator (Nr 1, Page 408) Create an application that lets the user enter a salesperson's revenue sale and the rate of commission paid by the company, and display the commission earned. For example: • If a salesperson sells $100,000 in revenue while working with a company that pays 5 percent of the revenue, his/her commission check will be $5,000. • if a salesperson sells $100,000 in revenue while working with a company that pays 8 percent of the revenuo, his/her commission check will be $8,000. The program should have a method named CalculateDisplayCommission that receives the revenue sale by a salesperson and the commission percentage as arguments, and calculates and displays the commission earned by the salesman. See examples below: Salesperson's Commis. |Salesperson's Commis. 100000 Revenue Sale: 100000 Revenue Sale: Commission Percentage: Commission…
TOPICS: Data and Expressions MUST BE IN JAVA. PLEASE USE COMMENTS AND WRITE THE CODE IN SIMPLEST FORM. Write an application that reads a value representing a number of seconds, then displays the equivalent amount of time as a combination of hours, minutes, and seconds. For example, 9999 seconds is equivalent to 2 hours, 46 minutes, and 39 seconds. Hint: This requires using the % modulus operator. The trick with multiple units of measure like this is to start with the largest unit (hours) and work down. Testing: Submit testing exhibits using the following inputs: 0, 1, 60, 3600, 3661, and 9999
Using C# in Microsoft Visual Studio create an application that lets the user play the game of Rock, Paper, Scissors against the computer. The program should work as follows:1. When the program begins, a random number in the range of 1 through 3 is generated. If the number is 1, then the computer has chosen rock. If the number is2, then the computer has chosen paper. If the number is 3, then the computer has chosen scissors. (Do not display the computer’s choice yet.)2. The user selects his or her choice of rock, paper, or scissors. To get this input you can use Button controls, or clickable PictureBox controls displaying some of the artwork that you will find in the student sample files.3. The computer’s choice is displayed.4. A winner is selected according to the following rules:• If one player chooses rock and the other player chooses scissors, then rock wins. (Rock smashes scissors.)• If one player chooses scissors and the other player chooses paper, then scissors wins. (Scissors…
