Write a class definition called RectangularSolid which takes three numeric parameters in its constructor, in this order: length, width, height. Provide a get_volume method that returns the volume of the rectangular solid. This method takes no parameters. Provide a get_surface_area method that returns the surface area of the rectangular solid. This method takes no parameters.

The class Shapes includes two void methods: calcTriangleArea( ) and calcTrianglePerimeter( ). The calcTriangleArea ( ) method takes two int parameters (base and height), calculates the area of a triangle, and assigns the value to a private instance variable (area). The calcTrianglePerimeter( ) method takes three int parameters (lengthSide1, lengthSide2, and lengthSide3), calculates the perimeter of a triangle, and assigns the value to a private instance variable (perimeter). The Shapes class also includes two getter methods, which return the calculated values. The Shapes class implements the Calculatable interface.Write the Shapes class and the Calculatable interface.
Write the definition of a class Player that has the following methods: • An __init__ method that initializes the following attribute variables: o An attribute variable named name , initialized to the empty string. o An attribute variable named score , initialized to the value 0. • A method named set_name that accepts one argument that is assigned to the attribute variable name . • A method named set_score that accepts one argument that is assigned to the attribute variable score . • A method named get_name that accepts no arguments, and returns the value of the attribute variable name . • A method named get_score that accepts no arguments, and returns the value of the attribute variable score .
Write a class 'Cylinder' that has two fields: height and radius. The class should have only one parameterized constructor function to initialize these fields. The class should also have a method 'getVolume()' to calculate the volume of this cylinder. Now, create any 2 objects of this class with arbitrary values and show their volumes.
This is for pygame Text Class The Text class inherits from Drawable and it will be used to display the player’s score. You must implement at the very least the required methods of the base class (draw and get_rect), as well as a constructor. You may need to implement other methods as part of the public interface. This is the Drawable Class
Please write the Java code for a Phone class that represents a mobile phone, as detailed below: It should have instance variables (attributes) for make, model, color (all stored as Strings) and capacity (stored as int: the storage capacity in GB) Please define one constructor with parameters for all those attributes. The Phone class will be immutable, except its storage capacity can be changed. So please write only one mutator method, called .setCapacity. Please write accessor methods for each instance variable. Please write a .toString() method to display all the Phone's information. Please write a .equals method to compare two Phone objects, returning true if all their attributes are the same. Finish the Jave program to show the outputs bellow: Code: class Main { public static void main(String[] args) { Phone craigPhone, bettoPhone, tobyPhone; craigPhone = new Phone("Samsung", "Galaxy S21 5G", "Phantom Violet", 256); bettoPhone = new Phone("Apple", "iPhone 13 Pro",…
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.
Create a class Course, which has one field: String courseName Create the constructor, accessor, and mutator for the class. Then, in the main method of this class, create an instance of the class with the name "CST1201". Write an equivalent while statement to replace the following for statement for (int i=2; i<100; i=i+2) { System.out.println(i); }
How many parameters does the following constructor have, and what are their types? public Book(String title, double price)
(The Rectangle class) Following the example of the Circle class in Section 8.2,design a class named Rectangle to represent a rectangle. The class contains:■ Two double data fields named width and height that specify the width andheight of the rectangle. The default values are 1 for both width and height.■ A no-arg constructor that creates a default rectangle.■ A constructor that creates a rectangle with the specified width and height.■ A method named getArea() that returns the area of this rectangle.■ A method named getPerimeter() that returns the perimeter.Draw the UML diagram for the class and then implement the class. Write a testprogram that creates two Rectangle objects—one with width 4 and height 40and the other with width 3.5 and height 35.9. Display the width, height, area,and perimeter of each rectangle in this order.
I need help in improving my Elevator class and it's subclasses code. I already provided my code at the bottom. This is an elevator simulator that uses polymorphism and object-oriented programming to simulate the movement of elevators in a building with multiple types of passengers and elevators. There are 4 types of elevators in the system:StandardElevator: This is the most common type of elevator and has a request percentage of 70%. Standard elevators have a maximum capacity of 10 passengers.ExpressElevator: This type of elevator has a request percentage of 20%. Express elevators have a maximum capacity of 8 passengers and are faster than standard elevators.FreightElevator: This type of elevator has a request percentage of 5%. Freight elevators have a maximum capacity of 5 passengers and are designed to transport heavy items.GlassElevator: This type of elevator has a request percentage of 5%. Glass elevators have a maximum capacity of 6 passengers and are designed to transport fragile…
You are required to build a class to represent the a cup of coffee. Call your class CoffeeCup. A coffee cup will have following characteristics 1. type (sting) // can be mocha, cupaccino, etc 2. temperature (float): represents the measure of temperature in degrees 3. volume (float):// the volume of coffee in the cup in ml liters 4. sugar (int):// no of teaspoons of sugar added to the coffee Provide these methods 1. parameterized constructor CoffeeCup(string t, float temp float vol, int sug) 2. Provide setters for temperature, and sugar and volume. 3. Provide getters of temperature, sugar, volume and type. 4. void heatUp(): //this method represents the process of heating the coffee, the current temperature of coffee goes up by one degree if it is below 100 and stays the same otherwise 5. void cooldown(): the process of cooling down. The temperature goes down by one degree but will not go below 0 6. bool isSweet():// returns true if this coffee has any amount of sugar in it and 0 if not…
Write a convertToMetric class that has the following field: standard - holds a double, standard length value in feet. The class should have the following methods: Constructor - that accepts a length in feet (as a double) and stores it in the standard field. setStandard - accepts a standard length in feet and stores it in standard. getStandard - returns the value of the standard field, as a length in feet, no conversion required. getMeters - returns the value of the standard field converted to meters. getCentimeters - returns the value of the standard field converted to centimeters A second class will be created and used to test the new object class. This, executable class, is to instantiate an object of 'convertToMetric' type. Then it will allow the user to use keyboard input to input a value for standard. That value will then be converted to meters and centimeters, and displayed. Make sure that your output (or display) is user-friendly or easy to read and understand. You should…
