Hi can you assist me on the problem below for a class and a test class that conforms to the following specifications: 1. The name of the class is RightTriangle 2. The class has member variables base and height 3. The class has a constructor that initializes base and height 4. The class has accessors and mutators for base and height 5. The class has a toString method that produces String representation of a RightTriangle like the following example for a triangle with base 12 and height 10. Base : 12 Height 10 6. The class has a method called findArea to compute the area of the right triangle. Here is a suggested implementation. public double findArea() { return 0.5* this.base*this.height; } 7. The class using proper naming conventions Write a test class called RightTriangleTest that conforms to the following: 1. Create an object with base = 10 and height = 20, for example myTriangle. 2. To print the toString for myTriangle. 3. To print the area of myTriangle. System.out.println(“The…
Complete the FoodItem class by adding a constructor to initialize a food item. The constructor should initialize the name (a string) to "None" and all other instance attributes to 0.0 by default. If the constructor is called with a food name, grams of fat, grams of carbohydrates, and grams of protein, the constructor should assign each instance attribute with the appropriate parameter value. The given program accepts as input a food item name, fat, carbs, and protein and the number of servings. The program creates a food item using the constructor parameters' default values and a food item using the input values. The program outputs the nutritional information and calories per serving for both food items. Ex: If the input is: M&M's 10.0 34.0 2.0 1.0 where M&M's is the food name, 10.0 is the grams of fat, 34.0 is the grams of carbohydrates, 2.0 is the grams of protein, and 1.0 is the number of servings, the output is: Nutritional information per serving of None: Fat: 0.00 g…
In this exercise, you are going to be working with 4 classes, a Book superclass with TextBook and Novel subclasses, and a BookTester class to run your program. For the Book, TextBook, and Novel class, you will create a constructor and all getters and setters. Be sure to follow standard naming conventions for your getters and setters! Additional information for each class is below. Book Class The Book class will have a title and author as instance variables and the constructor should follow this format: public Book(String title, String author) TextBook Class The TextBook class will have a subject and edition as instance variables and the constructor should follow this format: public TextBook(String title, String author, String subject, String edition) Novel Class The Novel class will have a genre and pages as instance variables and the constructor should follow this format: public Novel(String title, String author, String genre, int pages) BookTester In the tester class, you should…
a.) Write the definition of the default constructor of YClass so that the instance variables of YClasa are initialized to 0. b.) Write the definition of the default constructor of XClass so that the instance variable of XClass are initialized to 0. c.) Write the definition of the method two of YClass so that rhe instance variable a is initialized to the value of the first parameter of two, and the instance variable b is initialized to the value of the second parameter of two.
Help 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. exisiting code in different file: const double GALLONS_IN_A_CUBIC_FEET = 7.48; class swimmingPool { public: void set(double l = 0, double w = 0, double…

In Kotlin, Write a Circle data class, with a radius as a parameter to the constructor, a custom-coded property for the area, and a sizeRatio() function that takes a reference to another Circle and returns the ratio of the radius of the instance circle (the one you call the function on) to the other circle . Use math.pow and math.PI. Write a main() that creates a circle, prints it (which will print it's automatically generated toString()), prints its radius, creates another circle, and shows the size ratio of the two.
Can you call a constructor from another constructor? A solution is placed in the "solution" section to help you, but we would suggest you try to solve it on your own first. Problem Statement# A class can have multiple parameterized constructors which can call each other. You are given a partially completed code of a Car class in the editor. Modify the parametrized constructor which assigns parameters to the required fields. Input# carName, carModel, carCapacity Output# carName, carModel, carCapacity Sample Input# "Ferrari", "F8", "100" Sample Output# "Ferrari", "F8", "100" Part of solution // Car class class Car { // Private Fields private String carName; private String carModel; private String carCapacity; // Default Constructor public Car() { this.carName = ""; this.carModel = ""; this.carCapacity = ""; } // Parameterized Constructor 1 public Car(String name, String model) { this.carName = name; this.carModel = model; } // Parameterized Constructor 2 public…

Given the following class, I need help writing a constructor that initializes all instance variables using appropriate parameters. I need to make sure it enforces the preconditions public class BrowserTab {private String title;private int id;/*** Creates a BrowserTab* @precondition title != null && id >= 0*/}
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 program that has the following classes: Point - Just like in the lecture, with attributes x and y set to 0 by default. Circle - Contains two attributes, center and radius. center is of type Point defined above (initialize a Point instance for this), while radius is set to 0 by default. The program must have the function point_in_circle(c, p) where c is a Circle and p is a Point. The function returns True if the point is within the circle, and False otherwise. You may use the math module (and nothing else) if necessary. You may also create other functions that can help you code the main function much easier. Example usage # Initialize a circle with center at (0, 0) and radius 1 (unit circle). c = Circle() c.center.x, c.center.y, c.radius = 0, 0, 1 # Initialize a point located at (1, 1) p = Point() p.x, p.y = 1, 1 # This returns False since (1, 1) is outside the circle point_in_circle(c, p)
