Create a class named Checkup with fields that hold a patient number, two blood pressure figures (systolic and diastolic), and two cholesterol figures (LDL and HDL). Include methods to get and set each of the fields. Include a method named computeRatio() that divides LDL cholesterol by HDL cholesterol and displays the result. Include an additional method named explainRatio() that explains that HDL is known as “good cholesterol” and that a ratio of 3.5 or lower is considered optimum. Save the class as CheckupType.cpp. Create a tester program named TestCheckup whose main() method declares four Checkup objects. Call a getData() method four times. Within the method, prompt a user for values for each field for a Checkup, and return a Checkup object to the main() method where it is assigned to one of main()’s Checkup objects. Then, in main(), pass each Checkup object in turn to a showValues()method that displays the data. Blood pressure values are usually displayed with a slash between the…
You are given a Conversion class and need to complete it by adding two static methods. The first method should be called gallonsToPints and take a double gallons and return the number of pints as a double (1 gallon = 8 pints). The second method should be called feetToInches, also taking a double number of feet and returning the number of inches as a double (1 foot = 12 inches). Test your program in the ConversionTester class by printing out two conversions. In java
Write a class called Investment with fields called principal and interest. The constructor should set the values of those fields. There should be a method called value_after that returns the value of the investment after n years. The formula for this is p(1+i)ⁿ, where p is the principal, and i is the interest rate.
I need to write a jave program to keep track of a team sport. Write a class, Team.java, that has the following: * two private instance variables: a String named color and an int named score. * a default constructor with no parameters that initializes color to "Red" and score to zero. * a constructor that takes two parameters (one for each instance variable) and sets the values of the instance variables. * a public getter and setter method for each instance variable. * a toString method that returns the color and score in the following format: "Red Team with 0 points."
For this lab task, you will work with classes and objects. Create a class named text that works similar to the built-in string class. You will need to define a constructor that can be used to initialize objects of this new class with some literal text. Next, define three methods: to_upper() that will convert all characters to uppercase, reverse() that will reverse the text and length() that will return the length of the text. After you have completed this part, copy the following mainfunction to your code and check if the implementation is correct. int main() { text sample = "This is a sample text"; cout << sample.to_upper(); // This should display "THIS IS A SAMPLE TEXT" cout << endl;cout << sample.reverse(); // This should display "txet elpmas a si sihT"cout << endl; cout << sample.length(); // This should display 21 }
a. Carly's Catering provides meals for parties and special events. In Chapters 3 and 4, you created an Event class for the company. Now, make the following changes to the class: Currently, the class contains a field that holds the price for an Event. Now add another field that holds the price per guest, and add a public method to return its value. Currently, the class contains a constant for the price per guest. Replace that field with two fields—a lower price per guest that is $32, and a higher price per guest that is $35. Add a new method named isLargeEvent() that returns true if the number of guests is 50 or greater and otherwise returns false. Modify the method that sets the number of guests so that a large Event (more than 50 guests) uses the lower price per guest to set the new pricePerGuest field and calculate the total Event price. A small Event uses the higher price. Save the file as Event.java. b. In Chapter 4, you modified the EventDemo class to demonstrate two Event…
Please use Java to help me with the assignment below. The assignment: A microwave control panel has four buttons: one for increasing the time by 30 seconds, one for switching between power levels 1 and 2, a reset button, and a start button. Implement a class that simulates the microwave, with a method for each button. The method for the start button should print a message “Cooking for ... seconds at level ...”.
Create a class named Lease with fields that hold an apartment tenant’s name, apartmentnumber, monthly rent amount, and term of the lease in months. Include a constructor thatinitializes the name to “XXX”, the apartment number to 0, the rent to 1000, and the term to12. Also include methods to get and set each of the fields. Include a nonstatic methodnamed addPetFee() that adds $10 to the monthly rent value and calls a static methodnamed explainPetPolicy() that explains the pet fee. Save the class asLeaseYourlastname.java. Replace ‘Yourlastname’ with your real last name.b) Create a class named TestLease whose main() method declares four Lease objects. Call agetData() method three times. Within the method, prompt a user for values for each fieldfor a Lease, and return a Lease object to the main() method where it is assigned to one ofmain()’s Lease objects. Do not prompt the user for values for the fourth Lease object, but letit continue to hold the default values. Then, in main(), pass…
Following the example of the Rectangle class of Chapter 9 Exercise 1, design a class named Cuboid to represent a cuboid. The class contains: Three data fields named length, width, and height. A constructor that creates a cuboid with the specified length, width, and height. A method named getVolume() that returns the volume of this cuboid. Then, please create an object mycuboid = Cuboid (2, 3, 4), and invoke getVolume to print the volume of mycuboid.
Create a class named Billing that includes three overloaded computeBill()methods for a photo book store.•• When computeBill() receives a single parameter, it represents the price ofone photo book ordered. Add 8% tax, and return the total due.•• When computeBill() receives two parameters, they represent the price ofa photo book and the quantity ordered. Multiply the two values, add 8% tax,and return the total due.•• When computeBill() receives three parameters, they represent the price of aphoto book, the quantity ordered, and a coupon value. Multiply the quantityand price, reduce the result by the coupon value, and then add 8% tax andreturn the total due.Write a main() method that tests all three overloaded methods. Save theapplication as Billing.java.
I would like you to create a program that keeps track of the inventory (by make - e.g., Toyota) of cars on a used car lot. you will have to create two classes. The first is a simple Car class that consists of an inventory, make, and model. The second class you need to create for this challenge is the Lot. A Lot can contain many cars. Part 1 Write the Car constructor, get methods, and toString method. Part 2 Write the Car's increase and decrease inventory methods. Part 3 Edit the Car so it implements Comparable and compares Car instances based on their inventory in descending order. Part 4 Write the getCars and getCarsSorted methods of the Lot class. Part 5 Write the getInventory method of the Lot class. Part 6 Use a try/catch block in the Car's constructor so that it sets the inventory to 0 if the inventory passed to the constructor is not a valid integer. this is the output that should be produced by main: Make: [Toyota Camry (10), Toyota Prius (4), Toyota Rav4 (16)] [Hyundai…
