Question

(Geometry: MyRectangle2D class) Define the MyRectangle2D class that contains: Two double data fields named x and y that specify the center of the rectangle with getter and setter methods. (Assume the rectangle sides are parallel to the x- or y-axis.) The data fields width and height with getter and setter methods. A no-arg constructor that creates a default rectangle with (0, 0) for (x, y) and 1 for both width and height. A Constructor that creates a rectangle with the specified x, y, width, and height. A method getArea() that returns the area of the rectangle. A method getPerimeter() that returns the perimeter of the rectangle. A method contains(double x, double y) that returns true if the specified point (x, y) is inside this rectangle (see Figure 10.24a ). A method contains(MyRectangle2D r) that returns true if the specified rectangle is inside this rectangle (see Figure 10.24b ). A method overlaps(MyRectangle2D r) that returns true if the specified rectangle overlaps with this…

(Java) Question 5 Explain the answer step-by-step and include verbal explanation. Thank you! Write an interface as follows: The interface is named ServiceReminder It has one method named timeForService that has no parameters and returns a boolean variable. Now, update the below class so that is inherits from ServiceReminder Note that the next service date should be 90 days from the last service public abstract class Car { private double gasGauge; private double currMileage; private String color; private String make; private String model; private int daysLastService; public Car(String color, String make, String model, int daysLastService) { this.color = color; this.make = make; this.model = model; gasGauge = 0.0; currMileage = 0.0; this.daysLastService = daysLastService; } @Override public String toString() { return "Make: " + make + "\nModel: " + model + "\nColor: " + color…

(Enhancing Class Rectangle) Create a more sophisticated Rectangle class than the one youcreated in Exercise 17.11. This class stores only the Cartesian coordinates of the four corners of therectangle. The constructor calls a set function that accepts four sets of coordinates and verifies thateach of these is in the first quadrant with no single x- or y-coordinate larger than 20.0. The set function also verifies that the supplied coordinates do, in fact, specify a rectangle. Provide member functions that calculate the length, width, perimeter and area. The length is the larger of the twodimensions. Include a predicate function square that determines whether the rectangle is a square
