- Finish the TestPlane class that contains a main method that instantiates at least two Planes. Add instructions to instantiate your favorite plane and invoke each of the methods with a variety of parameter values to test each option within each method. To be able to test the functionality of each phase, you will add instructions to the main method in each phase.A class can have how many constructor methods? Only one constructor without parameters. Only one constructor with int parameter. Many constructors with same signatures. Many constructors with different signatures. Which answer pleasein this example we have two constructors with the same arguments which is going to confuse the compiler which constructor to call when we call it in main code by an object what is the solution for this problem without changing the number of the arguments in the constructors
- There should only be one constructor for every class. True FalseCan 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…The class "Car" has the following attributes: plate (String), mark (String), model (String), year (int), km (int).Write a constructor method for the "Car" class that takes values as parameters for all these attributes.
- Coupling is the amount two methods or classes know about one another. The more they know about one another, the more tightly coupled the design. True/FalseI have multiple constructors defined in a class. Is it possible to call a constructor from another constructor’s body?Modify the Car class example and add the following: A default constructor that initializes strings to “N/A” and numbers to zero. An overloaded constructor that takes in initial values to set your fields (6 parameters). accel() method: a void method that takes a double variable as a parameter and increases the speed of the car by that amount. brake() method: a void method that sets the speed to zero. To test your class, you will need to instantiate at least two different Car objects in the main method in the CarDemo class. Each of your objects should use a different constructor. For the object that uses the default constructor, you will need to invoke the mutator methods to assign values to your fields. Invoke the displayFeatures() method for both objects and display the variables. Demonstrate the use of the accessor method getColor() by accessing the color of each car and printing it to the console. Use the method accel to increase the speed of the first car by 65 mph. Use…
- Which two characteristics of the constructor set it out visually from the other methods of the class, and what are those characteristics?Must be written in Python. Please include docstring and show how output should look like. Remember that all data members should be private. An object can access it's own private data members directly. It can also access the private data members of other objects of the same class directly. But when accessing a private data member of an object of another class, it needs to call the appropriate get method. If that sounds complicated, just remember this: if a method is in the same class as a private data member, then it can access that data member directly, otherwise, it needs to use a get method. Write a class named Point that has two data members, x_coord and y_coord, representing the two coordinates of the point. It should have: an init method that takes two arguments, an x-coordinate and y-coordinate (in that order), and uses them to initialize the two data members. get methods for the two data members: get_x_coord and get_y_coord. a method named distance_to that takes a Point object…Design a LandTract class that has two fields (i.e. instance variables): one for the tract’s length(a double), and one for the width (a double). The class should have: a constructor that accepts arguments for the two fields a method that returns the tract’s area(i.e. length * width) an equals method that accepts a LandTract object as an argument. If the argument object holds the same data (i.e. length and width) as the calling object, this method should return true. Otherwise, it should return false. a toString method (that returns a String representation of the tract’s length, width, and area). Demonstrate the class in a program by creating an array of three LandTract objects initialized with user input. Then, print the info of the LandTract objects stored in the array by invoking the toString method (implicitly or explicity). Also, use the equals method to compare at least two LandTract objects and print wether they are of equal size or not. Sample Output:…
