Using JAVA!!!!Define the MyRectangle2D class that contains: Two double data fiel

Question

Using JAVA!!!!Define the MyRectangle2D class that contains:

Two double data fields named x and y that specify the center of the rectangle with get and set methods. (Assume that the rectangle sides are parallel to x or y axes.)

The data fields width and height with get and set 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 .

A method contains(MyRectangle2D r) that returns true if the specified rectangle is inside this rectangle.

A method contains(MyRectangle2D r) that returns true if the specified rectangle overlaps with this rectangle.

    MyRectangle2D r1 = new MyRectangle2D(2, 2, 5.5, 4.9);
    System.out.println("Area is " + r1.getArea());

    System.out.println(r1.contains(3, 3));
