- Assume that you have created a class named MyClass. The header of the MyClass constructor can be ____________. public MyClass() public MyClass (double d) Either of these can be the constructor header. Neither of these can be the constructor header.java Assignment Description: Write a class named Car that has the following fields: The yearModel field is an int that holds the car’s year model. The make field references a String object that holds the make of the car. The speed field is an int that holds the car’s current speed. In addition, the class should have the following constructor and other methods. The constructor should accept the car’s year and make as arguments. These values should be assigned to the object’s yearModel and make fields. The constructor should also assign 0 to the speed field. Constructor: The constructor should accept no arguments. Constructor: The constructor should accept the car’s year as argument.Assign the value to the object’s yearModel. No need to assign anything to the make and assign 0 to speed. Appropriate mutator methods should set the values in an object’s yearModel, make, and speed fields. Appropriate accessor methods should get the values stored in an object’s yearModel, make, and…This has to be done in visual studio, c# windows form application (.net fromework). Question: The application should be able to do the following :• Create a class called Person which contains 4 private fields : Name(string), Surname (string),Course(string), CRNumber(int).• The class must contain 4 public properties which will be used to get and set the values of the private fields.• The class must contain a default constructer. The class must also contain an overloaded constructer which should be able to set the values of each of the private fields.• The class must contain a static ViewInfo method which will be used to display information of a queue of person objects back to the user neatly grouped underneath each other as displayed above.• Once a user clicks on the “Add Person” button then the information in the respective textboxes should be used to create a Person object (using the properties or the overloaded constructor) and add it to a queue which is of type Person. The…
- Create a constructor for the Student class you created. The constructor should initialize each Student’s ID number to 9999, his or her points earned to 12, and credit hours to 3 (resulting in a grade point average of 4.0). Write a program that demonstrates that the constructor works by instantiating an object and displaying the initial values. Save the application as ShowStudent2.java.There must be classes and objects.Attributes are of type publicUse one or two constructors.Write a program in Object Oriented Java language that adds and subtracts two polynomials of the form ax2 +bx+cObject initializers let you assign values to any accessible properties of an object at creation time without having to invoke a constructor Question 19 options: a) True b) False
- (Date Class) Create a class called Date that includes three pieces of information as auto-implemented properties—a month (type int), a day (type int) and a year (type int). Your class should have a constructor that initializes the three automatic properties and assumes that the values provided are correct. Provide a method DisplayDate that displays the month, day and year separated by forward slashes (/). Write a test app named DateTest that demonstrates class Date’s capabilities.If a class has this method, it is called automatically just before an instance of the class is destroyed by the Java Virtual Machine.a. finalizeb. destroyc. removed. housekeeperWhen you redefine the __str__ method in a class, the keyword print has different meanings based on what objects are passed through it.

- Car ClassWrite a class named Car that has the following fields:• yearModel. The yearModel field is an int that holds the car’s year model.• make. The make field references a String object that holds the make of the car.• speed. The speed field is an int that holds the car’s current speed. In addition, the class should have the following constructor and other methods.• Constructor. The constructor should accept the car’s year model and make as arguments. These values should be assigned to the object’s yearModel and make fields. The constructor should also assign 0 to the speed field.• Accessors. Appropriate accessor methods should get the values stored in an object’s yearModel, make, and speed fields.• accelerate. The accelerate method should add 5 to the speed field each time it is called.• brake. The brake method should subtract 5 from the speed field each time it is called.Demonstrate the class in a program that creates a Car object, and then calls the accelerate method five…In Java programming (Lesson: Objects, Classes, and Constructors) Every class has a constructor and if we do not explicitly write a constructor for a class, the java compiler builds a default constructor for that class. False or True Please provide an explanation for the answer. Thank you!C# Which statement about default constructors is correct? Question 9 options: It is a parameterless constructor. It does not accept argument(s). It initializes the object's fields with the value 0 or null. All of the above.
