- T/F 2. Formal parameters are those that appear in the method call and actual parameters are those that appear in the method header.Exercises: PolymorphismProblem 1. VehiclesWrite a program that models 2 vehicles (Car and Truck) and will be able to simulate driving and refueling them inthe summer. Car and truck both have fuel quantity, fuel consumption in liters per km and can be driven givendistance and refueled with given liters. But in the summer both vehicles use air conditioner and their fuelconsumption per km is increased by 0.9 liters for the car and with 1.6 liters for the truck. Also the truck has a tinyhole in his tank and when it gets refueled it gets only 95% of given fuel. The car has no problems when refueling andadds all given fuel to its tank. If vehicle cannot travel given distance its fuel does not change.Input On the first line - information about the car in format {Car {fuel quantity} {liters per km}} On the second line – info about the truck in format {Truck {fuel quantity} {liters per km}} On third line - number of commands N that will be given on the next N lines On the next N lines –…True or False The versions of an overloaded method are distinguished by the number, type, and order of their parameters.
- a) Implement a class Point with three attributes, x, y, and z.b) Implement an init method with an optional parameter type: 1) Set the default value of x, y, and z to 0.c) Implement a display method to print the values of x, y, and z as the example output below.d) Instantiate two objects of type Point, one with arguments,1, 2, and 3, and the other one without any arguments.e) Call display() to print x, y, and z. Example Output(x, y, z): (1, 2, 3)(x, y, z) : (0, 0, 0)Code in C# (OOP Concept) Do a program that does the following: Ask for a number from the user in the main method o Pass thenumber to a method call it "Multiplication”. In the Method Multiplication, multiply the number by a number enteredby the user (mention that the number should be positive). Send the result back to the main and print it from the mainModify the previous program if the user enters a negative second number in the method Multiplication, do not acceptthe number and ask the user to reenter it again. . Add another method call it also Multiplication Ask for a float numberfrom the main and send it to the new Multiplication. This method should also ask for another positive number fromthe user and multiply it by the float number. Design and implement a function called "multiply" in C++ that accepttwo numbers and returns either the arithmetic multiplication or repetition of a given string a specific number of timesdepending on the data types of the argument values. The…Program62.javaWrite a program that prompts for a full name (first and last) and assigns it to one string. The program then passes the full name to a void method as its sole parameter. The void method should print the first name, on one line, as many times as indicated by the length of the last name. Sample Output (image below) Program64.javaWrite a program that demonstrates method overloading by defining and calling methods that return the area of a triangle, a rectangle, or a square.
- a. Plan the logic for an insurance company program to determine policy premiums. The program continuously prompts the user for an insurance policy number. When the user enters an appropriate sentinel value, end the program. Call a method that prompts each user for the type of policy needed—health or auto. While the user’s response does not indicate health or auto, continue to prompt the user. When the value is valid, return it from the method. Pass the user’s response to a new method where the premium is set and returned—$550 for a health policy or $225 for an auto policy. Display the results for each policy. b.Modify Exercise 9a so that the premium-setting method calls one of two additional methods—one that determines the health premium or one that determines the auto premium. The health insurance method asks users whether they smoke; the premium is $550 for smokers and $345 for nonsmokers. The auto insurance method asks users to enter the number of traffic tickets they have received…Methods are functions that belong to a class. Explain the concept of function definitions outside a class using the following scenario:A University needs to calculate the fees of students. Explain the required class and function definition outside the class clearly writing a program.use only C# programming Write a method call CubeIt(int x, ref int cube) that takes two arguments and does not return a value. The method will cube the first argument and assign it to the second argument.In your main, call this method twice and print the value of the parameters after each method call. Write a method with the following header: static void CalculateTuitionFee(int numberOfCourses, double costPerCourse, ref double fees). This method will calculate and assign the required fees amount to the third argument. [Fees = number of courses * cost per course + 15.25].From your program Main() method, call the CalculateTuitionFee () method four times supplying different arguments each time and display the value of the third argument after each method call. Write a method that takes four parameter of type int. The method will assign the sum of the first two arguments to the third and the difference of the first two to the fourth. This method should be coded so that the calling…
- a) Write a boolean method called sumDivisibleByFive that returns true if the sum of the digits of its integer parameter is divisible by 5 and false otherwise. For example, if the parameter passed to the method is 73 then the sum of its digits is 10 (7+3) The method should return true since 10 is divisible by 5. b) Write a main method that calls the method sumDivisibleByFive for the values between 10 and 100 inclusive 10 per line. This should output the following numbers: 14 19 23 28 32 3741 46 50 55 64 69 73 78 82 87 91 96T/F 2. The formal parameters occur in the procedure call, while the real parameters appear in the method header.All needed parameters must be passed in during method call.
