Build a class called Calculator that emulates basic functions of a calculator: add, subtract, multiply, divide, and clear. The class has one private member field, double value, for the calculator's current value. Implement the following Constructor and instance methods as listed below: public Calculator() - Constructor method to set the member field to 0.0 • public void add(double val) - add the parameter to the member field • public void subtract(double val) - subtract the parameter from the member field • public void multiply(double val) - multiply the member field by the parameter • public void divide(double val) - divide the member field by the parameter • public void clear() - set the member field to 0.0 • public double getValue() - return the member field Given two double input values num1 and num2, the program outputs the following values: 1. The initial value of the instance field, value 2. The value after adding num1 3. The value after multiplying by 3 4. The value after subtracting num2 5. The value after dividing by 2 6. The value after calling the clear() method Ex: If the input is: 10.0 5.0 the output is: 0.0 10.0 30.0 25.0 12.5 0.0

tri1 and tri2 are instances of the Triangle class. Attributes height and base of both tri1 and tri2 are read from input. In the Triangle class, define instance method print_info() with self as the parameter to output the following in one line: 'Height: ' The value of attribute height ', base: ' The value of attribute base
In this challenge, we'll implement an Account class along with two derived classes, Savings and Current. Problem Statement# Write a code that has: ● A parent class named Account. ○ Inside it define: ■ a protected double member balance ■ public void Withdraw(double amount) ■ public void Deposit(double amount) ■ public void printBalance() ● Then, there are two derived classes ○ Savings class ■ has a private member interestRate set to 0.8 ■ Withdraw(double amount) deducts amount from balance with interestRate ■ Deposit(double amount) adds amount in balance with interestRate ■ printBalance() displays the balance in the account ○ Current class ■ Withdraw(double amount) deducts amount from balance ■ Deposit(double amount) adds amount in balance ■ printBalance() displays the balance in the account Input# ● In the Savings class, balance is set to 50000 in the parametrized constructor ● In the Current class, balance is set to 50000 in the parametrized constructor Output# Balance before…
Write a class that tests and demonstrates that your Candidate and Electionclasses implement the specification given above. Note that this does not need to be a Junit test class.Your test class must illustrate all of the features that you have implemented. This will best be done by having at least one separate test method for each feature. For instance:• A method that creates a Candidate object and prints out the result of calling each of its accessor (get) methods; • A method that adds a vote to an existing Candidate object.• A method that creates an Election object, creates a few Candidateobjects and adds them to it, and then calls the printAll method;• A method that finds a matching Candidate;• A method that does not find a matching Candidate;• etc.Note that the list above is not a complete list of the test class’s methods and you will need to define more than those for this part. It will be worth writing this test class alongside writing the other classes. For instance, develop the…

Can you help me with this please: Write the definition of a class swimmingPool, to implement the properties of a swimming pool. Your class should have the instance variables to store the length (in feet), width (in feet), depth (in feet), the rate (in gallons per minute) at which the water is filling the pool, and the rate (in gallons per minute) at which the water is draining from the pool. Add appropriate constructors to initialize the instance variables. Also, add member functions to do the following: determine the amount of water needed to fill an empty or partially filled pool, determine the time needed to completely or partially fill or empty the pool, and add or drain water for a specific amount of time, if the water in the pool exceeds the total capacity of the pool, output "Pool overflow" to indicate that the water has breached capacity. The header file for the swimmingPool class has been provided for reference. Write a program to test your swimmingPool class. An example of…

The derived class Cat extends the Pet class and includes a private field for catBreed. Complete main() to: create a generic pet and print information using printInfo(). create a Cat pet, use printInfo() to print information, and add a statement to print the cat's breed using the getBreed() method.
Implement the Seller class as a derived class of Person class. Create the seller.h and seller.cppfiles for this class. The Seller class contains additional data members that hold a seller’s:o average star rating received from the buyers, ando total number of items sold.These data should be accessible by its derived classes. (should these data be private, public, orprotected?) The following methods are included in the seller class:• A default constructor and a copy constructor• A constructor that receives all of the data for a seller.(for the constructors, make sure to call the base class constructor as appropriate)• Appropriate get and set functions for the new data in this class• print() – overrides the base class print() to print the base class data and print all additionalseller data with appropriate messages. Make sure to call the base class print to print thebase class data.• read() – overrides the base class read() to read the base class data and reads all additionalseller data…
