Look at the following method header:
void displayPoint(Point<? extends Number> myPoint)
Which of the following objects would we be allowed to pass as an argument to the displayPoint method? (Select all that apply.)
a. Point<Number> p;
b. Point<Integer> p;
c. Point <Double> p;
d. Point <String> p;

- 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…arrow_forwardC++ programmingarrow_forward#pyhton programing topic: Introduction to Method and Designing class Method overloading & Constructor overloading ------------------ please find the attached imagearrow_forward

PerimeterTriangle - compute the perimeter of a trianglearrow_forwardIn C#, How would you compile the necessary code to define a class that will store a point in space. It will need the following data members: xcoord, ycoord. Include the following methods:- a default constructor that will set the coordinates to 0,0- a constructor that takes two values corresponding to the xcoord and ycoord values and sets them accordingly- accessor methods to get and set the values of the coordinates (you can use properties if you wish)- a display constructor that returns a string in the format of (xcoord, ycoord) Usage of the class: //create an instance of 2 points Point myPoint = new Point; //assign values using properties |If you do not declare properties for the data items, you might do the following myPoint.Xcoord = 42; |myPoint.SetX(42); myPoint.Ycoord = 19.63; |myPoint.SetY(19.63) // use the Display() method WriteLine(“The point is “+myPoint.Display()); //output The point…arrow_forward
