- Temp Class - Create Temp class whos job is to hold a temp in degrees F and gives methods to get the temp in F, Celsius, and Kelvin. The class should follow the instance variable (field): ftemp (double type that holds F temp)Follow these methods with the class.. Constructor --Will accept Fahrenheit temperature as a double to store it in the ftemp field. setFahrenheit - The setFahrenheit method accepts a Ftemperature as a doubleto stores it in the ftemp field. getFahrenheit - Returns the value of the ftemp field, as a Fahrenheit temperature (no conversion required). getCelsius - Returns the value of the ftemp field converted to Celsius. [C e l s i u s = ( 5.0 / 9.0 ) × ( F a h r e n h e i t − 32 )] getKelvin - Returns the value of the ftemp field converted to Kelvin. [K e l v i n = ( ( 5.0 / 9.0 ) × ( F a h r e n h e i t − 32 ) ) + 273] Exemplify the temp class by writing a (test) program that is separate and promotes users for an F Fahrenheit temp. The program must create an…Assignment:The BankAccount class models an account of a customer. A BankAccount has the followinginstance variables: A unique account id sequentially assigned when the Bank Account is created. A balance which represents the amount of money in the account A date created which is the date on which the account is created.The following methods are defined in the BankAccount class: Withdraw – subtract money from the balance Deposit – add money to the balance Inquiry on:o Balanceo Account ido Date createdCreate an Employee class. Attributes(must be private): Employee has a name and basic_salary Methods:Employee(string, float); //ConstructorAllowances are computed as: float getHouseRent(); //House rent is 45% of the basic pay. float getMedicalAllowance(); //Medical Allowance is 5% of the basic pay. float getConveyanceAllowance(); //Conveyance allowance is 10% of the basic payfloat getGrossPay(); //Salary including rent and allowances{You can implement additional function/s if needed} Then Create an Organization class. Organization has 10 Employees (Hint: You will need an array of pointers to Employee class) Organization can calculate the total amount to be paid to all employees Organization can print the details(name & salary) of all employees Note: Use main,header and functions.cpp to write code.
- Modified Circle class and test file: Add a new attribute for color (or any other new attribute) Add get/set methods for this new instance variable, including data validation in set method (assuming background is black, i.e. circle color can't be black, reset to any non-black color if black is entered ). Add a new constructor to pass the color attribute as an argument. Add an instance method to display all properties of a Circle object. Create 2 objects using different constructors in test file, with invalid data. Use this test java file test java file: class CircleTest{ public static void main(String[] args){ int num = 10; Circle c1 = new Circle(0.001); Circle c2 = new Circle("black", -9); c1.display(); c2.display(); c1.setRadius( -1); c1.setColor("black"); c1.display(); }}Rectangle Object Monitoring Create a Rectangle class that can compute the total area of all the created rectangle objects using static fields (variables). Remember that a Rectangle has two attributes: Length and Width. Implement the class by creating a computer program that will ask the user about three rectangle dimensions. The program should be able to display the total area of the three rectangle objects. For this exercise, you are required to apply all OOP concepts that you learned in class. Sample output: Enter Length R1: 1 Enter Width R1: 1 Enter Length R2: 2 Enter Width R2: 2 Enter Length R3: 3 Enter Width R3: 3 The total area of the rectangles is 14.00 Note: All characters in boldface are user inputs.Overview: A new bank wants to make a simple application to keep track of all accounts and transactions. it is required to help the bank manager implement the required application. Requirements: After a quick meeting with the bank manager, you got the following information: • tis required to store all bank accounts in one collection and all the transactions happened in another collection. Each account has a unique account number, a holder and balance. There is a specific prefix (common for all accounts) that should be added to the holder's civil id to create the unique account number. In addition, it is not allowed for a holder to have more than one account. Furthermore, only three transactions are allowed on any account: deposit, withdrawal and transfer money to another account. • Each holder has a unique civil ID (national id), a name and other attributes (add at least 2 attributes from your choice). • For each transaction, it is required to store the account(s) affected, amount of…
- C# languageCreate a class for “Plane” having functionalities (methods) startengine(), fly() and land(). When ever engine starts it should reset the attribute TTK (Total travel kilometer) to zero and attribute Fuel to 100. On fly() it should add 10 kilometers if the Fuel attribute is greater than zero and decrement Fuel by 20.On land() it should print total distance covered. Write the code providing all necessary details. And then show working object of Plane in main().Parent Class: Food Write a parent class called Food. A food is described by a name, the number of grams of sugar (as a whole number), and the number of grams of sodium (as a whole number). Core Class Components For the Food class, write: the complete class header the instance data variables a constructor that sets the instance data variables based on parameters getters and setters; use validity checking on the parameters where appropriate a toString method that returns a text representation of a Food object that includes all three characteristics of the food Class-Specific Method Write a method that calculates what percent of the daily recommended amount of sugar is contained in a food. The daily recommended amount might change, so the method takes in the daily allowance and then calculates the percentage. For example, let's say a food had 6 grams of sugar. If the daily allowance was 24 grams, the percent would be 0.25. For that same food, if the daily allowance was 36 grams, the…Code the StudentAccount class according to the class diagramMethods explanation:pay(double): doubleThis method is called when a student pays an amount towards outstanding fees. The balance isreduced by the amount received. The updated balance is returned by the method.addFees(double): doubleThis method is called to increase the balance by the amount received as a parameter. The updatedbalance is returned by the method.refund(): voidThis method is called when any monies owned to the student is paid out. This method can onlyrefund a student if the balance is negative. It displays the amount to be refunded and set thebalance to zero. (Use Math.abs(double) in your output message). If there is no refund, display anappropriate message.Test your StudentAccount class by creating objects and calling the methods addFees(), pay() andrefund(). Use toString() to display the object’s data after each method called
- Hints: • For each class, it is required to implement constructors, setters, getters, toString() method, and any other necessary method • If the user tries to do an operation that could violate the state of objects, the operation should be ignored and the application should display an error message (e.g. adding a passenger to the same trip twice, etc.) Checking equality of any 2 objects should be done via the equals() method • • Testing: After implementing the required classes, design and implement a testing class to test them as follows: There is a class that will do the main job of as follows: o It has one collection to store the whole data (all trips) o It has static methods, one for each operation happens frequently o For each adding or removing operation, a message should be displayed to the user to explain the status of the operation (i.e. if it was successful or not) • Create at least 7 trips in at least 3 different dates and add them to the collection that stores the whole data…15. The Date class as three private integer attributes (day, month, year) A user requests a new Date object method public String dayOfWeek() that returns a String with the day of the week for the Date instance the method is called on ("Mon", "Tues", "Wed") |A fellow programmer wants to add a private String attribute dayOfWeek to support this request, but I say we don't need the attribute since we can calculate the day of the week from the month, day, year http://en wikipedia org/wiki/Determination_of_the_day of the_week Why is my approach better?Library Information System Design and Testing Library Item Class Design and TestingDesign a class that holds the Library Item Information, with item name, author, publisher.
