Create a class definition based on the specifications provided below. Make sureyou use the proper C++ syntax in defining your class.Specifications:1. Class name is Area;2. It has 2 fields namely n1 and n2, declared as integer.3. The 2 fields must only be accessible within the class.4. There is a constructor that is capable of accepting values for 1field called x.5. There is another constructor that is capable of accepting valuesfor 2 fileds called x and y;6. Create the code inside the constructors. The codes will simplyassign value of x and y to n1 and n2, respectively.7. Specify the appropriate access modifier for the constructors.

1. Write a class named Coin. The Coin class should have the following field: • A String named sideUp. The sideUp field will hold either "heads" or "tails" indicating the side of the coin that is facing up. The Coin class should have the following methods: • A no-arg constructor that randomly determines the side of the coin that is facing up ("heads" or "tails") and initializes the sideUp field accordingly. • A void method named toss that simulates the tossing of the coin. When the toss method is called, it randomly determines the side of the coin that is facing up ("heads" or "tails") and sets the sideUp field accordingly. • A method named getSide Up that returns the value of the side Up field. Write a program that demonstrates the Coin class. The program should create an instance of the class and display the side that is initially facing up. Then, use a loop to toss the coin 20 times. Each time the coin is tossed, display the side that is facing up. The program should keep count of…
1. Create a class as described below: Class Name: Room Fields: standard room fee amenities total cost Constructors:A default constructor to initialize the fields. The standard room fee field should be set to $200 and the amenities field to zero. Another constructor with one argument. It should assign this value to the standard room fee and the amenities field to the default value of $75. Methods: getStandardFee() - This methods returns the standard room fee field value. getAmenities() - This method returns the amenities field value. getTotalCost() - This method returns the total cost field value. calcTotalCost() - This method calculated the total cost for an instance of the class setStandard Fee() - This method has one argument representing the standard room fee. setAmenities() - This method has one argument representing the amenities for the room.
You need a way to prevent class fields from being corrupted by mistake.
in C#, Visual Basic Create a Car class that has at least the following properties:• Year• Make• Price• Passengers-holds the number of seat belts available in the car (presumably how many passengers the car can hold). This field must be private since users presumably can’t change this value. Have two constructors: one that initializes everything to some default value for the base price of a car and one that also accepts values for luxury upgrades of: heated seats, sun-roof, and satellite radio. The class has two methods: 1) Get Paint Color() which accepts a standard base color option but allows the user to purchase a pricier customized color 2) Upgrade Costs() which computes the cost of user-selected luxury items and adds it to the price. Create three car objects: Ford (make Explorer), Lexus (make ES) and a Clown Car which overrides the passenger value to allow 20 clowns in the car. The Get Paint Color() and Upgrade Costs() functions needs to be called for each object and data for all…
Design a Ship class that has the following members:• A field for the name of the ship (a string).• A field for the year that the ship was built (a string).• A constructor and appropriate accessors and mutators.• A toString method that displays the ship's name and the year it was built.Disign a CruiseShip class that extends the Ship class. The CruiseShip class should have thefollowing members:• A field for the maximum number of passengers (an int).• A constructor and appropriate accessors and mutators.• A toString method that overrides the toString method in the base class. The CruiseShipclass's toString method should display only the ship's name and the maximum number ofpassengers.Design a CargoShip class that extends the Ship class. The CargoShip class should have thefollowing members:• A field for the cargo capacity in tonnage (an int).• A constructor and appropriate accessors and mutators.• A toString method that overrides the toString method in the base class. The CargoShipclass's…
Create a class of Dog, some of the differences you might have listed out maybe breed, age, size, color, etc.  Then create characteristics (breed, age, size, color) can form a data member for your object. Then list out the common behaviors of these dogs like sleep, sit, eat, etc. Design the class dogs with objects and methods.
Design a class named octopus that holds attributes for an octopus named weight and color. Include methods to set and get each of these attributes. Create the class diagram and write the class pseudocode that defines the class. Create a small program that declares two octopus objects and set the octopus's name weight and color attributes the program must also output each octopus's name weight and color after they are set. Please write out the pseudocode. I have a hard time with this.
